Hi all,
I'm trying to deploy to a server running Java 1.5 and I am getting the error A fatal exception occurred: Bad version number in .class file when I start up the app.
So on my development box:
I deleted all my frameworks.
I installed the binaries of Wonder Integration from Jenkins.
I have the compiler settings set to 1.5 in Eclipse, I deleted my frameworks' bin folders, then built inside Eclipse using Ant install....
Does anyone know how I could still be getting 1.6 byte code?
Thanks,
David
