As you can see from your code Netbeans can't find it from that path. Perhaps you need to refresh your project after the jar there.
So why are you trying to run the jar file from your code any way? Why can't people just double click that jar file if they want to run it?

sory for taking so Long..

i'm using eclipse IDE,,

As you can see,, those jar (jrdesktop-0.3b.jar) was intended to be run inside my java app..

in future development i want handle an event click to run those jar from my app..

id don not want user to run those jar without my application.
(i assume in billing application,, only my application permitted to be run)

any suggestion for me ?

thx..

Instead of running the jar file, why not just do what it's main class' main method does on the event handler?

[point_Base]

i'm sory, but i dont know what you meant..

sorry..

would you explain to me..

[r035198x]

The jar file is runnable so it has a main class specified in it's manifest. The main method of that main class is going to be run when that jar file is clicked. So in your handler you can just do

MainClass.main(null);
