EXE won't run

I created a small project to view Jasper Reports.

When I run it from the Jabaco IDE, everything works fine.

When I run it as a generated exe, I see the following debug info in the console :

How can I resolve this ?



Thanks ! Frank (Belgium)

The Exe is just a self-extracting Jar archive which unpacks itself in %TEMP% and then executes "java -jar xyz.jar".
To pin down the problem you could compile your project into a Jar file rather than in an exe file.
Select filetype "Jar File" in the "File/Make Project" dialog.
If the resulting Jar file is runnable, the problem is due to the unpacking step.

You could rename the Jar into xyz.zip and unpack the contents to look at the Manifest file.

Have you changes something in your Module1? Your "main()" method might have a problem.

Success!
