大牛们，卡在这个地方好几天了，每次使用它都给我一个Null Pointer Exception，
领导下命令，2天做好，求大牛门指点下。connectionFactory 这一行就出错。哎。公
司会解雇我嘛？
谢谢。
public void publishMessage(HashMap notifyMessage)
{
try
{
TopicConnection connection = connectionFactory.
createTopicConnection(JMSCredentials.getUserId(),JMSCredentials.getPassword(
));
connection.start();
TopicSession topicSession = connection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
TopicPublisher publisher = topicSession.createPublisher(topic);
ObjectMessage msg = topicSession.createObjectMessage();
msg.setObject(notifyMessage);
publisher.publish(msg);
publisher.close();
topicSession.close();
connection.close();
}
catch (JMSException e) {
log.debug(e);
throw new RuntimeException(e);
}
}
