public void run() {
		try {
			String mess;
			while (flag == true) {

						String sender = me[1];
						String context = me[2];

						Message newMess = new Message();
						newMess.setUserno(user.getPhone());
						newMess.setSender(sender);

					} else {
						System.out.println(Arrays.toString(me));

					e.printStackTrace();
				}

			e.printStackTrace();
		}catch(Exception e1){
			e1.printStackTrace();
		}

这段代码在debug as的时候没有问题，但是一run as 就会报下面的错误，

java.io.StreamCorruptedException: invalid type code: 0B
	at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1356)
	at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351)
	at com.mypack.thread.RecThread.run(RecThread.java:40)

	at com.mypack.thread.RecThread.run(RecThread.java:40)

其中第40行也就是

mess = user.getOis().readObject().toString();

而且，在上面的那个判断语句怎么都能执行，在下面的else出的就执行不了，下面是服务器的发送代码

public void sendMess(List<ServUser> list, String[] str) {
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
		// Date date=new Date();
		String date = sdf.format(new Date());
		for (ServUser serv : list) {
			if (serv.getPhoneno().equals(str[2])) {
				try {
					serv.getOos().writeObject("Mess+" + str[1] + "+" + str[3] + "+" + date);
					serv.getOos().flush();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}	
			}
		}
	}
	public void sendPhone(ServUser user, String mess){
		String str1="phone";
		try {
			user.getOos().writeObject("phone+"+str1);	
			user.getOos().flush();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

sendMess()对应接受的if判断的那个并且没有出错，sendPhone（）发送时出错了............
大神们看看这是怎么回事啊，跪求大神啦！！！java新手，代码乱了还请别见外！！！
