When you generate a client and a J2SE Bean together, a .war file is generated and placed into the my-project\repos\my-service.deploymy-project/repos/my-service.deploy directory. The simultaneous generation of both a client and J2SE Bean is supported for Tomcat only.
You can undeploy an application .war file from a Web browser providing a URL constructed as follows:
