Re: Modify files in .jar libraries

The fact is that I'm not allowed to modify the file in .jar packet.
I want to change some code in libraries to allowing the double click
management with image widget...
So my problem is to add a handler to Image.java file in gwt-user.jar
packet.. But I can't!!
Maybe it's a permission matter?
