Hi there,
I m new to ejb and webloic. I have weblogic 5.1 and sp 9 and working on linux
7.0.
I tried to deploy the Emp ejb in the weblogic, which is in the Example/intro dir.

So i compile the java file and make the jar file and also chaged all those stuff
what needs to be changed.
But when I run the startWeblogic.sh. It gave me following error.
