Hi,
I've been trying to create a very simple example of a stateless session bean in EJB3.
I get the following error:
exception

JDK version is 1.6, working with JBoss 4.0.5, JBoss EJB3 RC9, and the JBoss Eclipse IDE.
I've deployed the ear and war files. When that didn't work, I also deployed the
jar file. I have MathEJB.jar containing the bean, MathWeb.war containing the web files
(index.jsp), and Math.ear containing MathEJB.jar, MathWeb.war, and application.xml.
I've been somewhat following
http://docs.jboss.org/ejb3/app-server/tutorial/stateless/stateless.html.
I should also note that JBoss Eclipse IDE won't automatically deploy the files; I have
to manually copy them. When I try to "run" them, it says those type of modules
can't run.
Apparently I can't attach files, so I'll copy the code.

Thanks for any help.
