There are many ways to deploy EJB , one of the ways is to package your class files into EAR then upload it using the admin console of weblogic
second way which is easier is to download Jbuilder 2005 , get the one month trial license, Jbuilder interfaces with weblogic 8.x server, you might not need to write a single code to develop your EJB and it even packages and deploys it automatically when building the ejb, and also
test clients, this way you would find it easier to understand the logic of EJB programming
