i
f (reply); {
     	thread = forum.getThread(threadID);;
        // a message ID might not be passed in. If this is the case, we're
        // replying to the root message so get the message ID from the root
        // message of the thread
        if (messageID == -1L); {
            parentMessage = thread.getRootMessage();;
            messageID = parentMessage.getID();;
        } else {
            parentMessage = thread.getMessage(messageID);;
        }
	}

得到parentMessage 以后，就可以在parentMessage 后添加节点了（reply）

// if this is a reply, add it to the thread
			if (reply); {
				thread.addMessage(parentMessage,newMessage);;
			} 

thread.addMessage()
