org.rhq.enterprise.communications.command.impl.generic.GenericCommandClient
Provides a client API for any generic, custom command. Somewhat different than the typical command client implementation, users of this class must utilize the {@link #setCommandType(CommandType)} to set the type of commandprior to invoking via the {@link #invoke(Map)} method. This class can be used to send any command via the{@link #invoke(Command)} method (without the need to call {@link #setCommandType(CommandType)}. @author John Mazzitelli

                ServerEndpoint serverEndpoint = AgentUtils.getServerEndpoint(agent.getConfiguration(), args[1]);


                // use the generic client utility to issue the command
                RemoteCommunicator rc = agent.createServerRemoteCommunicator(serverEndpoint.transport,
                    serverEndpoint.namePort.address, serverEndpoint.namePort.port, serverEndpoint.transportParams);
                GenericCommandClient client = new GenericCommandClient(rc);


                out.println(MSG.getMsg(AgentI18NResourceKeys.IDENTIFY_ASK_REMOTE_SERVER_FOR_ID, args[1]));
                sender.preprocessCommand(command);
                CommandResponse response = client.invoke(command);


                client.disconnectRemoteCommunicator();
