I believe JOnAS is one of the few servers that still requires manual generation of stub and skeleton code. It’s unfortunate, since it makes it much harder to use. Additionally, there’s no help for doing that in MyEclipse, since it’s very server specific. You’ll likely have to use the tools provided with JOnAS, by pointing them at your project directory, and then import the generated code into your MyEclipse project. If you have some server flexibility, JBoss 4.0 works well and automatically generates the classes as needed when the application is deployed.
