I am new to JBoss, and evaluating whether the next project is possible to use it as production or not. But I face some problem on it. The first is, how to use JDBC datasource from JBOSS. The second is, how to communicate between two EJB (both is in different package). I follow the instruction from the documentation, but seem that it doesn't work(throwing classnotfound exception, looks like it can't found the home class that i looking for) Hope can get some help, if possible pls give me some examples.
