When you access enterprise beans from a remote Java client application, it requires specific classes to use the client view of the enterprise beans. The Deploy service can pack the interfaces, stubs, and skeletons of the EJB application in a JAR file, which is created in the directory you specified.
You must select an application that contains enterprise beans. Otherwise, the Deploy service will not be able to create the client JAR.
You can use this client JAR to build your Java client application and access the enterprise bean. To be able to do this you have to set a classpath reference from the Java client application to this client JAR.
