I just did a new install of idm 3 on a sles9 box

The install seemed to go fine
I used port 8081 for jboss because imanager is using 8080

installed the userapp and when I went to http://ip addy:8081/IDM

i get an error
java.lang.NoClassDefFoundError

I am new to Linux and new to IDM.
so im hoping its something easy that i have over looked

Thanks
Mike
