我想发送JMS中的对象消息,但出现了运行时异常。
请为我提供可能的解决方案。
JMS 代码:
创建了新的MessageData类以代替创建子类MessageData之后,当我运行代码时,出现以下异常:
JMS 代码:
ObjectMessage objMessage = session.createObjectMessage();
MessageData data = new MessageData();
objMessage.setObject(data);
sender.send(objMessage);
在控制台上发现异常:
log4j:WARN No appenders could be found for logger org.jboss.remoting.transport.socket.MicroSocketClientInvoker).
log4j:WARN Please initialize the log4j system properly.

我正在尝试向ESB服务器代码发送一个对象消息。 针对上述情况,您有什么控制台窗口建议吗?
