you gotta be kidding that this guy wrote EJB code that only works on JBoss-3.0.0beta2, how did he do that ?
Just get the latest release JBoss-3.0.1RC1 and run the examples on that one.
If you run into a problem, post the stackTrace and the source to the appriopriate forum and we'll let you know what is wrong ;-)
if you read my message correctly you will notice me saying : "post the stacktrace to the appropriate forum" and this does not mean : "send me a 1.2 MB private mail with the sources"
Will you please post the stack trace you are getting to the EJB forum ?
