running enterprise application client from netbeans 5.5

When I created an enterprise application (an ejb module and java enterprise application client ejb3) in NetBeans 5.5 and deployed and ran it in sun appserver 9 it worked fine and the client displayed the required result. However if I removed the app client and added a different client, when I run the entrrprise application again it deploys but the new app client doesn't run. If I replaced the app client with the orginal app client again it deploys but doesn't run. How do I get the deployed enterprise application client to run from netbeans? I'm sure the answer is very simple. I would appreciate any help

Thanks.
