For those interested: I tried it and it works perfectly in the described way on the same host. Next step was to try it from a remote computer, as an application client usually is not installed on the server. So I copied all jars and replaced the jndi IP, but I got: | 2009-02-12 10:51:35,821 WARN [main][org.jboss.client.AppClientMain] - <Failed to | launch using: org.jboss.ejb3.client.ClientLauncher> | java.lang.IllegalStateException: Incompletely deployed: | | *** DEPLOYMENTS MISSING DEPENDENCIES: Name -> Dependency{Required State:Actual S | tate} | ClientContainer -> null{Installed:** UNRESOLVED JndiDepends: 'ConverterClient/me | taData' **} | | at org.jboss.kernel.plugins.deployment.AbstractKernelDeployer.internalVa | lidate(AbstractKernelDeployer.java:290) | at org.jboss.kernel.plugins.deployment.AbstractKernelDeployer.validate(A | bstractKernelDeployer.java:174) | at org.jboss.ejb3.client.ClientLauncher.validate(ClientLauncher.java:471 | ) | at org.jboss.ejb3.client.ClientLauncher.launch(ClientLauncher.java:269) | at org.jboss.ejb3.client.ClientLauncher.launch(ClientLauncher.java:174) | at org.jboss.ejb3.client.ClientLauncher.launch(ClientLauncher.java:138) | at org.jboss.client.AppClientMain.main(AppClientMain.java:134) | Using jBoss 5.0.0 GA. One thing I noticed was that the class path does not contain the client classes or the client.jar. That means all classes are fetched from the server?? When I included the client class and its dependencies in the class path of the launcher script, it worked also on a remote machine.
