Hi,
I've been trying the following project on Jboss ( initially from SUN J2EE tutorial ).
Depolyment of EJB to Jboss is ok, but when I try the ConverterClient, I got the following
error:
Caught an unexpected exception!
javax.naming.NameNotFoundException: comp not bound
at org.jnp.server.NamingServer.getBinding(NamingServer.java:529)
