You use reflection when you actually instantiate the objects or invoke the method.
In the EJB Scenario Beans invoke other Beans as clients. The client only looks up the objects (not instantiating) and the operations are invoked on the stubs only.
InitialContext ctx = new InitialContext();Object value = ctx.lookup(BEAN_JNDI_NAME);EJBHome ejbHome = (EJBHome) javax.rmi.PortableRemoteObject.narrow(value, EJBHome.class);EJBMetaData metaData = ejbHome.getEJBMetaData();Class homeClass = metaData.getHomeInterfaceClass();Class remoteClass = metaData.getRemoteInterfaceClass();// add this line, so you get an object of the home interface typeejbHome = (EJBHome) javax.rmi.PortableRemoteObject.narrow(ejbHome, homeClass);// create the remote objectMethod methodCreate = homeClass.getDeclaredMethod("create", null);//Call a method on the remote interfaceEJBObject remoteObj = (EJBObject)methodCreate.invoke(ejbHome, null);Method methodGet = remoteClass.getDeclaredMethod(METHOD_NAME, params);
