高分求java的C/S模式中怎么来传递一个对象？

Question

c/s模式下传递还是通过URL来传递吧.

Answer 1

你是怎么实现writeObject和readObject接口的？代码不贴出来，没人知道问题在哪里。

Answer 2

CS的传送对象的方法和BS是一样的啊，都需要先序列化，然后通过协议传送到远端，同过什么协议要看你的程序环境了WebApp和WebServise是不同的。

Answer 4

你的代码写得真是...
你把Exception都catch干吗，抛出去
还有，PersonInfo不能是两个...
while(s.name.equals("Bye")!=true)这里可能会死循环
ClientSocket=new Socket("10.10.147.246",8000);这个ip对么？
你先别急着搞这个程序，慢慢来先练好基本功再说

Answer 5

不批了，该批的楼上已经批了。指出问题，把这句的注释去掉！
 //   ObjectOutputStream  out1=new ObjectOutputStream(ConnectedClient.getOutputStream());

Answer 6

或者把这句注释掉
is=new ObjectInputStream(ClientSocket.getInputStream());C/S端要对应。
