Thanks for your response, jaikiran,
I just wanted to make sure I wasn't going to run into trouble.
Actually, it looks to me like the Duke's Bank example does deploy successfully with relatively minor changes.
- change the classpath entries for the servlet, jsp, and web service jars in the jboss build files.
- update the schema definitions referenced in application.xml and application-client.xml
If it is true that there are no EJB2 tutorials for AS 5.x -- and I wasn't able to find any -- this one still seems to be a workable alternative.
