Hi,
I know of two alternatives. The first is the "wrapper" and the second is
the "compiler". The wrapper works like a executable launch script that will
launch your main() with the local VM. On the other hand, the compiler will
compile your jar, with the VM, into a binary executable.

One of my favorite wrappers, the one I use, is exe4j
(http://www.ej-technologies.com/products/exe4j/overview.html). To compile
my jars into an executable, I used Excelsior JET (expensive
do)(http://www.excelsior-usa.com/jet.html). Here's other choices :

http://launch4j.sourceforge.net/

Hope this helps

You got to include "manefest" file containing the class name
of the "main()" method as;

Main-class: your.package.Class_NAME

make it as follows;

"jar cmf manest your.jar includefiles ..."

For details, read the Java Tutorial, JAR section.

Cheers.
