I don't often get on my soapbox, but I feel it's time for this. Stop whining! This refers specifically to application development, but I guess it can be applied to most everything. The point I am talking about is application frameworks.
I am using JavaFX, which is relatively new. The problem it is trying to solve is to remove the cruft from desktop application development (Swing), add 2d animations, and be able to run on a variety of devices and platforms. For me the holy grail of Java development would be to create an application that runs on mobile, desktop, and browser, all using the same code! JavaFX does this nicely. Some application development people won't even look at it because features like menus are not there yet. Are there some things missing? Yes, but there is a difference between “where's function X?” and “Epic fail! I can't do anything because function X is missing!”.
All languages, especially new ones have holes in them. You must learn to work around things, that's why I call myself a hacker. Would I want to have something work out of the box? Of course I would, but I also understand that knowledge comes with getting your hands dirty. Just because I can't drag and drop a control doesn't mean it doesn't work. I think the rule of thumb for me is, if the work takes more code than the application I am working on, then's it's broken. I think the whining is more apparent in the younger guys, because of the great things we can do in our IDEs. Not to sound like a greybeard (but I will anyway) is that I started coding Java in NOTEPAD! The same is true with HTML and XML. I love that code completion and other useful features have become standard now, but I bring this point up for a reason. I know how to fix it when breaks, because I know how it's put together.
Sure code is tough, but if you think writing an application is tough, you should see what it takes to write an API. The application development “magic” doesn't write itself. If something doesn't work right, investigate it, instead of complaining. You may have the key fix to make it great. I know you will learn something during your research. You can't drag that control, so you will wait until it's so easy, even a caveman can do it. If you do, you may be replaced by a cheaper caveman.

Yes, this is another of my continuing series of JavaFX posts. I hope you are enjoying the posts, and hopefully you will take a look at JavaFX, because it's really going to be a great platform. One of the key complaints from some application development folks is “yea it does cool animations, but where's the non-trivial uses?”. True there has been a lot of “toy” applications, some touted as “Enterprise”, but I want to give you a key usage for your business application development.
First off a brief primer on JPA, or Java Persistent API. The technology grew out of the complexity and (loathing) of the EJB 2.0 spec. Hibernate came up with way to use POJOs to persist data. The brains behind JPA were the driving force behind JPA. Now is the time to learn JPA, because it's a big part of the EE 6 spec.
Some notices here first; I am using NetBeans as my IDE. You should be able to use the general theme with Eclipse though. JavaFX can use Java classes in the script. The key part for me was how to integrate them. The easiest thing to is create a new Desktop application project (New Project → Java → Desktop Application). Pick the database application, so the JPA wizard displays. Select your table, and the wizard creates the JPA controller, and all of the Entity classes for you. Run the Build project, and now you have a JAR file. If you don't have NetBeans, or want to do this by hand, create the Controller and Entity classes and put them in a JAR file. Add the JAR file to your JavaFX project path, and your ready to go! The following Code can be put in your script to access:

To display all of the values, you can run a for loop like this:

The code above iterates through the List object created by findYourTableEntites, and puts it in a Vertical Box (Vbox). Each item in the Box is a Text object whose display value is one of your fields from your table.

You can now dynamically populate your fields from a database, but more importantly, you are using JPA to handle all of the heavy lifting. Notice I didn't mention anything JDBC. I let JPA do all of the communicating with the database. This is a layer abstraction that let's be an application development guy, not a DBA or Network Admin (not that there's anything wrong with that). If you are using an application server that handles JPA like Glassfish, then you can make your JavaFX application available on the browser and desktop. Now you can have that awesome looking application that actually does something. You are happy to start doing something cool, and your boss is happy because it does something he wants.

First, sorry for the tardiness of my posts. Between the holidays, coming back from the holidays, a cold, and a secret project (for now), I haven't had time to blog.. until now. My current focus has been a Facebook game application. Well it's still in the alpha phase, but I wanted to get the architecture up and running. There's nothing worse for an application development person than to finish your application, then find out you need to rewrite it (or worse) because of the architecture doesn't support it. Even without Zembly, setting up a Facebook application is pretty easy. Since I had most of the defaults already in, the only thing I need to do is to tell Facebook where my application resides. Since I don't have Zembly anymore, I have to put on my application development and network administrator hats on set up an application server.
My first test was to deploy the application into my local Tomcat. NetBeans does a great job of having the files available to you, but the thing you learn quickly is that there isn't a simple deployment piece. Tomcat needs a WAR file, so I tried to use the JAR command to WAR up the files in the dist folder. No dice. The war file needs a proper web.xml file to work properly. Rather than use workarounds on workarounds, I created a web application project in NetBeans, linked the jar file from my JavaFX project, and copied the JNLP and HTML files to my new project. I now have a WAR to deploy. Tomcat loves this file. I run and... “FILE NOT FOUND?” was heard all throughout Cincinnati. Your JNLP file that was created points to a servlet called internally by NetBeans. Make sure change the following lines:

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://your server.com/app path/" href="SBWarsTest_browser.jnlp">
<information>
<title>SBWarsTest</title>
<vendor>STAR BASE </vendor>
<homepage href="http://your server.com/app path/"/>

Once I made the change to localhost, everything was fine. Now I wanted a real application server, so I downloaded and installed Glassfish V.2.1 on one of our servers, changed the JNLP file and we are in business. I tried to hit it from my machine, and no dice. After some extensive research, I found out the the Java 7 EA JRE does not play well with JavaFX. I uninstalled it (which reverted to JRE 1.6.18), and it works. In Facebook, you need to set the canvas callback URL to your host application path. The result is the pretty picture you see at the top of my post.

Happy New Year!!!  Welcome to a new year, new decade and a new beginning. 

As the recession recedes and recovery takes hold, IT executives are looking at their project lists and trying to decide what their priorities are.  Should we do application development in house or bring in an IT consulting company?  Should we consider an open source application?   What is the ROI?  What’s a company to do?   It doesn’t matter if your company is in Cincinnati, Dayton or Katmandu, the questions are the same.

Last month we did a pulse survey to see how IT leaders are managing ROI measurement.  The results were surprising and sparked a lot of conversation here at STAR BASE, Inc.  The thing that surprised us the most was the number of companies that did NOT look at ROI before doing a project.   Most of our respondents (58%) do not.

Some of conversations we have had revolved around the idea of doing a project or installing an application just to stay in the game.   Could you imagine a company of any size today functioning without email?  I could argue that there is negative ROI with amount of time managing my email in box takes! 

For those that measure ROI, only about half see the actual ROI align with the projected ROI most of the time.  The other half report that they see the actual ROI align with the projected ROI less than half the time and most said seldom or never.  I have often said that if management knew how much it was really going to cost to install that new ERP system before they started, they probably wouldn’t.

Since most of our respondents don’t look at ROI and of those that did, half said the ROI did not align, my question is this:  How do you decide what projects to do?  Are most companies spending money on IT because they need to “keep up with the Jones’ “?  Is it because installing that new ERP will look good on everyone’s resume?

According to ComputerWorld, web application development remains top dog by far in the top IT skills to have in 2010.  Specifically, companies will look for developers with knowledge of .Net, Java, Web development, open source and portal technologies.  The article goes on to suggest that combining web application development skills with business analysis or project management skills is a big plus.  ComputerWorld lists the remaining skills to have for 2010 in its top six as:  Help Desk/Technical Support, Networking, Project Management, Security and Business Intelligence.

I feel ComputerWorld did not put enough emphasis on Security; this without doubt will be the biggest challenge for IT executives in the coming years.  Open-source software may be an innovative money saver, but IT professionals still have concerns that networks could be vulnerable to viruses, cyberattacks and other intrusions.

According to InfoWorld, a new survey from Forrester Research found that 58 percent of large companies have security concerns about open source. In addition, 57 percent of small and mid-sized businesses expressed concern that open-source software would be "complex and hard to adopt".

With the advent and increasing usage of open-source in the business world, expect to see demand for IT security related skills to grow.  According to the FLOSS 2020 roadmap presented at the Open World Forum in Paris, 40 percent of jobs will be related in some way to open source by 2020.  You can expect application development and security to comprise a great majority of these jobs.
 

When I went to JavaOne this year, I had some friends who went to the Google I/O conference a few days before. Besides getting a new G2 phone (lucky), they were raving about Google Wave. Google recently released Wave into beta, and I have had a chance to play with it.
For those who do not know, Google Wave is a new type of communication software that allows real time collaboration. I know, it sounds all buzzwordy, but it is real cool. Think of Wave as email, SMS, and a working SharePoint all in one. To start a Wave you select new and a text area displays. Select from your contacts to add people, write some text and press send. Sounds like email right? Well, what if after some correspondence, you need to bring other people into the loop? And those late comers are now asking new questions? I don't know about you, but I get confused trying to read emails with lot's of history, and getting new emails based off of some of that history. Google Wave fixes this because everyone is updating a single thread in real time. If you are added late, there is a play button to show the order of the messages. Since it is in real time, all response are shown when entered. You could follow a meeting while listening to a conference call, and ask questions during the meeting, instead of having a second meeting to discuss the first meeting.
Collaboration is the key aspect of Wave. I am using Wave to let some people in Brazil help me test my JavaFX application. As a Cincinnati based application development person, this already saves me time and money. I added a zip file, and instructions on how to use it. I can get their feedback, and update the zip file. I think all application development people can see how useful this is. I can update my code to my users, and have a history of feedback. This will work well for those “confused” management types who “forgot” their feedback.

Google Wave is also a development platform. You can create your own widgets to run on Google Wave. The widgets provided by Google are a poll widget, collaborative Sudoku, and emoticons. I have used the poll widget, and works nicely. If you have a yes/no/maybe question to ask, it really is useful. I have an idea of using TTS to create “talking” Waves.

The one thing I would like to point out is that you will be able to run the Google Wave engine on your boxes. That means you can have a “private” Wave and a “public” Wave. You can set access restrictions on Wave, so you can have control of who uses Wave. Now that it is in beta, look for an invite and get riding!

I have recently discussed my application development with JavaFX. After using it for a while, I am generally impressed. I come from a Swing background, so desktop application development is not difficult. The concepts that you will most use are sequences, binding, and triggers. Sequences are arrays of objects, but JavaFX makes it easier to use. You can use an index of course, but the insert and delete keywords give more control. You can simply add to the end of the sequence, or insert or delete before or after any item in the sequence. The hardest thing to deal with is that there are no multi-level arrays in JavaFX.

Bind and triggers are an interesting way to dynamically update values on the screen. They seemed awkward to me first, but once you get the hang of it, they work well. You can use the bind keyword assign a variable or attribute a dynamic value. There are times though that the runtime won't update. Instead of Listeners, JavaFX uses the on replace keyword to change the value in runtime. Anything inside the brackets will fire when the value changes. Just update the bound variable in the on replace, and the runtime will update. It seems like you are creating the same value twice, but it is a better way to control runtime events, without a bunch of unused Listeners taking up space.

For most application development people, it is the ability to customize and extend controls that makes a language useful. One thing that I have been doing is creating custom groups. Each control, (Text, buttons, progress Bar, etc) are actually a node on a scene. You can use the Group container to combine the controls into a single class. The Group control is more than a container because application development people can add special attributes that affect the group. I have created a group of polygons that act as buttons. I can't use the ButtonGroup control, so I change the selected button and hover color inside the class by using attributes. The cool thing though, is that I don't create the mouse events in the class, but when I create the group. The mouse events interact with variable on my main class, so there isn't any coupling of my custom class to my main class. That means I can use my polygon buttons in any project I wish.

The are many different effects that you can apply to the controls, too many in fact. As most application development folk don't have a solid background in graphics, a solid guide on gradients, reflection, glowing and other effects, and animation would be great. I just don't know how to control some effects, and I am still learning how to blend effects to make things look cool. That tutorial or book would be my new best friend.

Recently, I have been talking about the virtues of Zembly to allow application development people to deploy their Java, JavaFX, and PHP applications to social networking sites like Facebook. Well, the Zembly team has notified everyone that the service will be shut down at the end of the month. I am guessing that this is the first round of “baggage” to be cut from the Sun/Oracle merger. On the surface it makes sense, since it is not a widely known framework, and canning the people will save them money. As a Java developer, I find the situation to be very difficult. Facebook is primarily a PHP site, with lots of Flash added in, and any avenue to move other frameworks to fight Flash is a good one. Can I still perform Facebook application development? Yes, but it is poorly documented, and the documentation on Facebook is PHP biased. It was nice to use a framework to do the heavy lifting because I don't have to worry about the plumbing, just the creative aspects. This is not important when writing an accounting application, but is very important in game application development.

Goodbye Zembly, we hardly knew ye.

I was reading this article and as a Cincinnati based IT consulting firm owner, found it interesting.  Social networks are influencing our everyday lives more and more each day.  This research was conducted by Don Bulmer from SAP and Vanessa DiMauro  According to them, there were six key findings:

1. Professional decision-making is becoming more social - enter the era of Social Media Peer Groups (SMPG).
Professionals want to be collaborative in the decision-cycle but not be marketed or sold to online; however online marketing is a preferred activity by companies.
2. The big three have emerged as leading professional networks: LinkedIn, Facebook & Twitter.
The convergence of Internet, mobile, and social media has taken significant shape as professionals rely on anywhere access to information, relationships and networks.
3. Professional networks are emerging as decision-support tools.
Decision-makers are broadening reach to gather information especially among active users.
4. Professionals trust online information almost as much as information gotten from in-person.
Information obtained from offline networks still have highest levels of trust with slight advantage over online (offline: 92% - combined strongly/somewhat trust; online: 83% combined strongly/somewhat trust).
5. Reliance on web-based professional networks and online communities has increased significantly over the past 3 years.
Three quarters of respondents rely on professional networks to support business decisions
6. Social Media use patterns are not pre-determined by age or organizational affiliation.
Younger (20-35) and older professionals (55+) are more active users of social tools than middle aged professionals.
There are more people collaborating outside their company wall than within their organizational intranet.

After reading this, a Bad Company tune came to mind, “Run with the Pack”.  There is certainly safety in numbers.  My question is this:  If everyone is doing the same thing, are they giving up any competitive advantages?

 

“IT executives increasingly implement marketing initiatives to improve the communications with their business customers. But these efforts often focus solely on the brand aspects of the services under the IT’s control without understanding the business’ perception of IT. To maximize the success, IT must add business satisfaction assessments to its tool kit. Understanding business satisfaction requires qualitative and quantitative data that capture customer expectations and perceptions through different types of interactions such as interviews, panels, focus groups, complaint systems, and surveys. This report provides best-practice recommendations, survey templates, and questions to guide IT executives through the deployment of a business satisfaction assessment. It applies Forrester’s deep expertise in external customer satisfaction to the interface between business customers and their internal IT suppliers.” says a new Forrester report.

I have served on countless business application development teams within several organizations in the Southwest Ohio and Cincinnati Information Technology community, one thing I can say is that most IT organizations do not gauge business satisfaction with IT business solutions.  I have served in only a couple of organizations where the business serves on the IT governance committee.  An organization does not have to be “big” to have an IT governance committee.  No matter what the size of the organization decisions are made as to priorities in IT work.  IT governance does not have to be a long drawn out process or take great time commitment from the business or IT executives, but business involvement in IT governance goes a long way in gaining business buy-in as you roll out the IT business solutions to the business.

Involvement in IT governance is just one way that many organizations in the Greater Cincinnati area can improve the IT-business relationship.  The Forrester report goes into ways to solicit and gauge business satisfaction with IT business solutions.  Doing so should affect decisions concerning not only IT business solution delivery but also IT Infrastructure and IT outsourcing initiatives.

 

I am part of the LinkedIn community and a member of several groups in LinkedIn.  One of the groups I am a member of is the IBM i Professionals group.  I get a weekly summary of activity and sometimes there are comments on the posts that people have made.  Usually there are no more than 3-5 comments.  What caught my attention is a LinkedIn post that had 23 comments.   The original post referenced this blog post:  http://blog.angustheitchap.com/?p=159  In this post, the author talks about the iSeries application development community needing to pull together to DO something about the lack of support for the platform.  He asks the question: What have YOU done for the IBM i platform this week?

As a former iSeries application developer, I thought it was a good question, perhaps about 10 years too late, but a good question none the less.  Let me state for the record that the iSeries is a great platform and it is without a doubt the best box for business that IBM has. 

The problem is that it is a victim of its own success.  There is no other platform where an application written in the 1980’s could still run un-touched even though the underlying hardware has changed numerous times.  To me the core issue is this: IBM is no longer in the hardware business; meaning they don’t derive that much revenue from hardware anymore.  The majority of IBM’s revenue comes from services.  The iSeries does not need or generate the services revenue that other platforms do.  So in my opinion, it’s an economic issue and no amount of doing or community is going to change that.

I recently read an article about the state of the IBM “i” and the amount of complaining by IBM application development and business partner folk. I know several RPG application development folk, and it sounds familiar. That made me think about my Java Application development and career. Are there things to complain about, and uncertainty about the future? Yes, but there are 2 reasons why the Java community is in a better place; the business model and the community. Before the IBMers call for a holy war, I said COMMUNITY! I am not talking about the strengths or weaknesses of the hardware or software. The business model for IBM is that they make the hardware and software, and partner for the sales and service. I think that is a viable model until IBM competes in the sales and services with their partners. If a lead is brought in by a small partner, they are awarded by giving the business to someone bigger. This sets up a confrontational relationship between IBM, the big partners, and the little partners. IBM can also decide whether or not you are worthy to be a partner. Why does this affect the software application development team? Because most consulting firm are selling SERVICES not HARDWARE. If they are not seeing business because of political fighting, they don't have to sell it. There are viable options on other platforms, where interference does not happen. IBM never fostered a community, they created a hierarchy with themselves as the head.

Certainly Sun has done some things that made myself and others unhappy. Besides, complaining, we actively pushed to remove barriers in our path. We do have an open source Java. Is there a IBM community that can work with RPG to make it work for them? I also think its about scale and timing. It's not like IBM software developers have their own AS/400 at their home. It's easy for me to create and use nearly any kind of application at my home in Cincinnati, and pretty cheaply. It makes it fun to tell non-technical people about my application development. Nobody but accountants want to hear about accounting programs. Java, and newer languages have grown up with the Internet. I have friends from all over the globe that have similar interests. If I have a problem, I can go online to a forum, friend, or web page to find what I need. I can read and write blogs to voice my opinion (like now). These things are not ingrained in the Legacy community, and in fact, have been actively campaigned against. It is my belief that any software, hardware, or service will die when there is no vocal community to support it.

As a consultant and application development person, I have to learn new things all the time. Take for example, my work with JavaFX. The language does have some familiar aspects, but there is a lot new there too. How do you go about learning something new? I have come up with some guidelines that I use in learning new things (in this case a language):

• Read as much about it as you can first. No one wants to wade through tomes of technical information, but that is where you learn. I try to get a feel for what problem the new thing is trying to solve first.
• Understand the core elements. Whether it's a programming language, a car, or a philosophical construct, knowing how it works is the first step. I know it's time to go to the next step when I have some ideas on how to use the item, and I start formulating a project.
• Examine and breakdown examples, if you can. You would be surprised at how many application development people think they're “smart enough” to figure out how things work just by following a few examples. I don't know about you, but I don't figure out a complex things just from a few simple “Hello World” examples. That being said, seeing how things works is the quickest to way get a basic understanding. Couple that with knowledge you acquired by reading the manual, and you get the “why” of how it's put together.
• Create your own knowledge base. I like to Google more than most people, but things do need to get done. I will create a separate folder to contain links to examples, other application development team members' blogs, white papers and other documentation. If you can, create a “how-to” WIKI. Having a centrally located repository makes it simple to answer questions.
• Create a test project. I do this especially for languages. I create a test project where I can test specific “how do I?” questions. It keeps you from removing code, adding unnecessary functions, and commenting and uncommenting code in your main project. Figure it out in its own project first, then transfer the code and knowledge to your main project. It is always good to revisit it after a period inactivity.
• Write or teach what you learned. As application development people, we tend to get blinders on when doing something. Having a different set eyes, or different questions being asked makes you examine what you actually know.

   

So there's my “Secret Sauce” for learning. You still have to come up with ideas on how to utilize you knowledge though.

In part one; I talked about some of the IT Strategies and business strategies that were discussed at the Techserve Alliance conference we recently attended.  I’ll admit I’m a sucker for quaint sayings and one of the speakers had a good one:  It’s time to take the Basset hound to the farm.  So what does that have to do with IT Strategy or business?

Plenty, takin’ the basset hound to the farm means it’s time to re-think what you are doing, why you are doing it, and who is doing it.  It’s time to eliminate products, services, processes or people that are not delivering value to the business.  This is not just an IT strategy, but an important business strategy as well.  It is critically important to make sure both business and IT are aligned. 

The trick is to figure out what your basset hound(s) are.  Every business that has been around for any length of time has one or more of these.  It may be a line of products that are kept in stock because it “rounds out the product line”, when the reality is the items are not that important.   It could be a service that our “customers really want”, but in reality  the service does not deliver value or it could be that “special process” that you do “because we have always done it that way”.  Then there is Bob.  Everybody likes Bob. Bob has been around forever and knows everything.  The problem is Bob doesn’t really do anything.

It’s always better to take the basset hound to the farm on your own terms rather than be forced into it by circumstances.  Take for example the company in New England that manufactured parts for submarines.  When the ship yard closed a few years ago, they were forced to change.  They redeployed their manufacturing expertise and now make parts for the medical industry.  What could they have accomplished if they had manufactured both parts for submarines and medical devices?  Could the business have been double the size?

That’s where an outside consultant can help.  They can be objective and bring an outside perspective to your current business and IT strategy.  STAR BASE is in a good position to teach old dogs new tricks”.  (Who let the dogs out? Who? Who?!)

People outside of Cincinnati may be shocked to know that I work with languages OUTSIDE of Java! I don't know any application development person, especially one who does web application development who doesn't use several languages. I have recently been working on Magento. What is that you say? Magento is an Open Source PHP ECommerce application based on the Zend Framework. You don't need to download Zend, just the Magento PHP files. We actually have Magento internally setup with a LAMP package, but I already have MySQL and Apache on my local machine, so I thought I'd tackle and individual install. The verdict? Well after a couple of small hiccups (don't use the Windows install for PHP, just unzip, and localhost needs to be a virtual host), setup was a breeze!  Fortunately, STAR BASE, Inc. has enough experience to over come these issues.  Magento is easy to customize products and catalogs, and would be a good choice for organizations to create their own ECommerce site. Magento is easy enough to implement without an IT Consultant, but an experienced consultant can save you time and frustration.

Seems like it has been a while since I have had a chance to do a post.  For the last 3 weeks things have been absolutely crazy in our IT consulting world, but in a good way.  We had a chance to go to the Techserve Alliance national conference in Las Vegas.  I have heard all the jokes, including the one about it staying in Vegas.   We did learn that just because you are pre-checked with the airline, does not mean that your bags are.   We got our bags checked with literally a minute to spare and fortunately all made it back to Cincinnati.

Upon return, we signed a support contract for a new customer.  They trust us enough to outsource their entire IT applications support to us.  We have a real life example of an IT Strategy that was discussed at the conference (See #3).  Not only was IT strategy discussed but business strategy as well.  Here are some highlights:

1. Market Differentiation - customers have lots of choices, how will you stand out?

2. Improve Systems and methodology for delivering service- excellence, efficiency, depth of service.

3. Outsource what you can-eliminate the busy work that does not add strategic value.

4. Deal with the economy being slow to recover till 2012, spend your money wisely, hire wisely, fire quickly, and refine what is working, stop what is not.           

5. Build Alliances with like minded providers in different industries and sell collaboratively to serve the customers' need.

My favorite of these five is number four.  Said another way, its takin’ the basset hound to the farm.  I’ll expand more on that in my next post.
