The .jar file has always been a great unit of modularity on the Java platform. Unfortunately, it also comes with the classpath baggage, and .jar files were never treated as first class components. OSGi is the next generation component platform that will bring greater modularity to the Java platform. In my previous blog, I showed the simplest OSGi components imaginable. Now I want to expand on that slightly by introducing a third component that exposes a key architectural and design benefit enabled by OSGi.

Lately, I’ve been experimenting more with OSGi, and I want to share some of the examples I’ve put together. The examples involve Felix, Spring Dynamic Modules, and Jetty, though could easily be used with Equinox. Once I’m finished with these exercises, I’m hoping to compare and contrast the different approaches I’ve taken, as well as comparing embedded Jetty with the Equinox Servlet Bridge. I’m a believer that OSGi is a disruptive technology that stands to transform Java development as we know it today.

Some of you may have seen this video explaining the placement of phony job ads that are subsequently used to prove to the Department of Labor that there is an IT labor shortage. Lou Dobbs also got in on the mix as shown in this YouTube video, or take a look at the transcript. This ammunition is used to secure green cards for H-1B Visa workers. It’s repulsive. Bottom line - there is no IT labor shortage.

Here are some more numbers from the Dobbs video. Universities are pumping out over 300,000 bachelors, masters, or PhD degrees annually in computer or information science, math, and engineering. The Department of Labor predicts the average yearly job creation in those fields to be 120,000 jobs.

I’m a believer in competition, but it must be fair. Data suggests that on average, H-1B Visa Holders are paid between $12,500 and $20,000 less than their American counterparts. I’m not anti-H-1B. I’ve worked with a large share of very good developers who were H-1B visa holders. Unfortunately, the H-1B visa program is being used to replace the jobs of U.S. IT professionals with cheaper labor.

A two pronged approach is required to fix the problem and requires a professional code of conduct between employees and employers. The result is a win-win-win situation for all involved. First, we need not eliminate or minimize the H-1B visa program, but instead must bring the salaries of visa holders up to levels equal to that of their American peers. Second, we must reform IT through incremental delivery of quality software. Until these happen, U.S. citizens will continue to suffer job loss due to anti-competitive and fraudulent practices.
