Re: [Condor-users] problem executing jar file

Thanks Ben, 
I have now managed to solve the problem.  The reason it didn't work was because the main class inside the Jar file needs to be specified as the executable instead of the .jar file itself.

Can you explain what you mean by this?

> Initialdir = /home/users/a4131673

Have you tried running it without the Initialdir set? It may be 
that Condor cannot locate the jar file.
