When I choose the "+ Fat Jar Exporter" and press the "next"-button following error appears:
The selected wizard could not be started.
Plug-in net.sf.fjep.fatjar was unable to load class net.sf.fjep.fatjar.wizard.FJExportWizard.
Bad version number in .class file
I've no idea how to solve that problem. Did I not properly installed the plug-in? It lies in the plug-in folder an I've started eclipse from the terminal with -clean
I'm using eclipse Version 3.4.1 and net.sf.fjep.fatjar_0.0.29.jar on OSX Leopard.
Would be nice if anybody could help me.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
how did you install Fat-Jar (Update-URL or Download ZIP-File)?
What JDK do you use?
I assume it is 1.4.x.
I rebuilt the Plug-In with jdk 1.4 to be compatible, perhaps I missed it in the Update-URL and it was built using JDK 1.5.
I will take a look at it.
Best regards,

To answer your questions:
- I dowloaded the ZIP-File (and put the jar into the plugin-directory)
- Hmm, I think I'm using JDK 1.5.0. My Projectfolder contains "JRE System Library [JVM 1.5.0 (MacOS X Default)]". Are there any Preferences where I can switch between the JDKs?
speaking of preferences I've just found the "Fat Jar Preferences". When I select it, another error message apears:
Unable to create the selected preference page.
java.lang.UnsupportedClassVersionError
Details:
Unable to create the selected preference page.
Bad version number in .class file.
Thank you for your support!

I can confirm that this same exact thing happens regardless of whether you deploy manually or use the Update Site. I get the exact same behavior as described above.

Hi,
I am using JBuilder 2008 turbo (eclipse based), and was having the same problem. I added
-vm "C:\Program Files\Java\jdk1.6.0_12\bin\javaw.exe"
to the JBuilder shortcut, and now fat jar is ok.
Maybe something similar will work for you,
Paulo

With release 0.0.31 this issue should finally be fixed!
Uffffff...
Installed Eclipse 3.1.2 to select Class-File Compatibility 1.1 and Source-Compatibility 1.3. Must also be possible with newer releases, but I was unable to figure it out.
Tested with jdk1.4.2 and Eclipse 3.5M5 (preferences appeared)

I can confirm that this same exact thing happens regardless of whether you deploy manually or use the Update Site. I get the exact same behavior as described above.
I am also seeing the same problem.
I am running Eclipse 3.4.2 on MacOSX Leopard 10.5.6
The JVM that eclipse is using is 1.5.0_16-133.
Same thing here. I tried manual as well as using the update site also, same result. MyEclipse 7.0 20081201, JVM 1.5.0_11-b03.

The problem should be fixed with the build 0.0.30 of Fat-Jar.
Sorry for the inconvenience.
Hello Fritz,
the problem should be fixed with the build 0.0.30 of Fat-Jar.
I tested the version with jdk1.4.2 on Eclipse 3.4.2 and 3.5M5.
Sorry for the inconvenience.

I don´t believe it!
Something odd happens with my laptop,
please still be patient.

You did it! Thanks Mr. Hechler!
I've tried it out (Eclipse: 3.4.1, JVM 1.5.0, OSX 10.5.2) and could export my first _fat.jar! Jeaaah!
(Well, the jar-launcher still can't find some libraries. But that's another story, probably my fault. Maybe I'll post a new Thread later)
Thanks again!
