I am a beginner in EJB 2.0. I have started with EJB 2.0 and following Head First EJB. I am using J2EE RI as the EJB server as has been suggested in the book. The first example in the book uses a standalone java client which simply prints a message on the console. The deployment works perfectly but when I try to run the client java class I get a binding exception which states that the JNDI context is an unknown source.
