    Help, what is the problem for my client,  JNDI or deployment

    Kun Men Newbie

      Would anybody please help me on my issue? thanks your advice in advance!
      Followed the 'duke bank' example in Startguide, I write a simple example. which only has one EJB and a client. By 'ant -f jboss-build.xml deploy', I have deployed it to the Jboss 4.0.2 (default server), and it is said it has been success deployed and started. However, when I run the client by 'ant -f jboss-build.xml run-client', I got such errors:

      I don't know what is wrong with it, actually I have deployed it by 'sun deploytool' to the sun j2ee sdk 1.4 default server, and everything work perfect. So I guess the problem is caused by the JNDI or the deployment descriptor of my client. Here I give all the info:
