socket连接得不到输入流，急救了！！！

[liushui05]

Socket s = new Socket("192.168.0.253", 8020);
ObjectOutputStream oos=new ObjectOutputStream(s.getOutputStream());
oos.flush();
msg+="\n";
oos.writeObject(byte2hex(msg.getBytes()));//转码处理
oos.flush();
ObjectInputStream ios = new ObjectInputStream(s.getInputStream());
//此处报错了，s.getInputStream()得到的好像是null

String inMsg=(String)ios.readObject();
System.out.println(new String(hex2byte(inMsg)));//解码处理
//jt.append(inMsg+"\n");
oos.close();

请高手看看这是什么问题
