Stream closed error!

[rishath]

I have designed a Tunneling Proxy server in java. I have opened an InputStream and OutputStream for a socket. After writing to the socket using the OutputStream, i'm closing only the output stream.

//ProxyConnection class
try {
   toServer = new Socket(host,port);
   Proxy.display("open connection to:"+toServer+"(timeout="+timeout+" ms)");
   
   
    clientIn = fromClient.getInputStream();
   clientOut = new BufferedOutputStream(fromClient.getOutputStream());
   serverIn = toServer.getInputStream();
   serverOut = new BufferedOutputStream(toServer.getOutputStream());
   
   
  URL u=new URL("anyurl");
    BufferedReader in=new BufferedReader(new InputStreamReader(u.openStream()));
    String str;
    
    while((str=in.readLine())!=null)
    {
        clientOut.write(str.getBytes());
        Proxy.println(str);
               
        
    }
  
    clientOut.close();

while(r0!=0 || r1!=0 || (time1-time0)<=timeout) 
      {
        Proxy.println("r0= "+r0+"r1= "+r1);
        while((r0=clientIn.available())>0) //This is where I get the error 
        { 
                    -------
        }

I get the following error, when I try to use the InputStream for the same socket.

java.io.IOException: Stream closed.

	at java.net.PlainSocketImpl.available(Unknown Source)
	at java.net.SocketInputStream.available(Unknown Source)
	at ProxyConnection.run(Proxy.java:131)
	at Proxy.run(Proxy.java:249)
	at Proxy.main(Proxy.java:284)

Is there anyway I can use the InputStream of that socket?
