This solution is written coz of the problem i have faced for almost a week and after a huge panic, i came to find an alternate solution to solve the problem.
The problem is Java Synthetica BlackEye Look and Feel with the desktop application. Well, if you try to place a tool bar over your desktop application, you will

Disclaimer: While optimizations can be fun and addictive, determine if your particular application needs any before attempting to optimize it.

I've always wondered if the Java compiler was capable of performing certain loop optimizations. So for fun, I picked a two of them (a simple permutation and loop unrolling) and tested them out.

We get many members here on the forums posting Java jobs or talking about Java careers.
Because of this we decided to branch out and create a dedicated Java careers site.

If you are looking for a career in Java or are looking to change from your current job, please visit Java Programming Careers - Java Developer Jobs, IT Jobs

If you need career advice, or would like to know more about being a full time Java developer, feel free to contact me or post in the forum ...

Normally for native access, I would use JNI to run native code, especially code I've written which interfaces with Java components. However, often you just want to call native functions (particularly system calls).

Rather than having to go through the whole JNI process (which is rather painstakingly slow), someone has created the JNA library which allows you to basically call native methods directly.
