Creating an executable JAR file for SWT Plug-in - Runnable JAR

You would have developed a small utility application, and now you wanted to create an executable JAR for that application.

Basically, end user should be able to launch the application by just double clicking on that.

Eclipse provides an option called “Runnable JAR” in the export menu items to perform this.

This will generate Plugin_Refactor_x86_1.0.jar file, including with all the required swt jars. 

Since swt native jars will be platform specific, we need to generate 32 bit or 64 bit files separately.
