accept()接到请求后为什么不执行下面的

[cqupt_feng]

//服务器部分
class Watch extends Thread
{
Index index;
Frame1 f;
Client c;
Watch(Frame1 f,Index index)
{
this.index=index;
this.f=f;
}

public void run()
{
try
{
index.socket=index.ss.accept();//程序好象只运行到这里
}
catch(IOException e)
{
f.l1.add(String.valueOf(e.getMessage()));
}
f.l1.add("有新客户连接");//为什么老是不执行这行,与客户连接成功就应该执行啊...
Client c=new Client(index.socket, this.f);
c.start();
while(true)
{

while(index.socket!=null);
try
{
Thread.sleep(400);
}
catch(Exception e)
{}
}
}
}

//客户端部分

try
{
socket=new Socket("172.18.100.76",4567);

if(socket!=null)
{
f.l.add("connect success");
ps=new PrintStream(socket.getOutputStream());
StringBuffer info=new StringBuffer("fffffffff");
ps.print(info);
ps.flush();
Thread c=new Client(socket,f);
c.start();


}
}

乱七八遭
好好google一下socket编程的src看看

[cqupt_feng]

谢谢前辈门提的意见啊,这是我在CSDN的第一贴..谢谢你们.

[wssssw]

还真是需要好好看看书啊
要把服务器代码和客户端代码放在不同的进程，至少是不同的线程

[xiaosun2]

index.socket=index.ss.accept();发生阻塞了， 因为你的程序是window程序吧，比如你在服务器端想点击一个按钮来启动socket监听，这个时候就会发生阻塞，解决该种类型的阻塞的方法就是，在你点击一个按钮的时候开辟一个新的线程来进入run()方法以启动socket监听。你不妨试一下。

.........还是不行啊...麻烦哪个前辈帮我看看啊。..

chatprogram文件内是服务端、
主函数在Index.java里
Frame.java 的对象是框架
Watch .java里循环等待客户发来的请求
client.java是 收发数据的

chatprogram_client是客户端
和chatprogram 一样
