I made a GUI with SWT/JFACE in eclipse. Unfortunately I am not able to create a working .exe file from this project. I created a .jar file which contains all the neccessary libraries etc. I can doubleclick on the .jar and the program opens and works fine. but when I start the conversion with JET 3.70 I get this screen: I think this might happen because I use dynamic paths to the library? Then I followed the instruction on this page: http://www.excelsior-usa.com/kb/000010.html unfortunately the newly created eclipse program keeps crashing. so I am not able to work with this version. well I am pretty much at the end of ideas how to fix these problems. I am trying to make this work for several days now with no luck. Does anybody have some useful tips? thanks in advance.
