I am trying the Sun tutorial Convertee EE sample. It works on local host but does not deploy on a remote AWS host. I've compiled, built and deployed it on a Local Glassfish 3.1.2 Application Server. It works as intended. But when I try to deploy on a remote (on an AWS EC2 instance) Glassfish 3 Server it deploys but does not work. JEE is well-known for ease of changing such server deployments. Normally, there should be no difference. The error message is Could not find file ${wa.copy.client.jar.from} blah blah I am clueless regarding the reason. Why does the App Client that works locally, fails to work in the remote instance. Both are glassfish 3.1.2. I am using Netbeans 7.2.1
