Hi,

I wrote a simple Client and Server using Socket and ServerSocket.

Running both Client and Server on the same machine everything works
fine. Running on different machines accept() returns a new Socket
Object.
from my Client request. But reading and writing on the Socket blocks.

Have I made something wrong? Ist the any mechanism from the host
administrator,
which accepts an connect but no read and write?

Thanks, by

This is the program from java in a nutshell examples:


public class HttpMirror
{
  public static void main( String args[] )
  {
    try
    {
      int iPort = Integer.parseInt( args[0] );
      ServerSocket ss = new ServerSocket( iPort );
      System.out.println( "New Server on Port: " + iPort );
      while( true )
      {
        Socket client = ss.accept();
        System.out.println( "Acceptet" );
        BufferedReader in =  new BufferedReader(
                  new InputStreamReader( client.getInputStream() ));
        PrintWriter out = new PrintWriter(
                  new OutputStreamWriter(  client.getOutputStream() ));
        out.println( "HTTP/1.0 200" );
        out.println( "Content-Type: text/plain" );
        out.println();
        out.flush();

        String sLine;
        while(( sLine = in.readLine()) != null )
        {
          if( sLine.length() == 0 )
            break;
          out.println( sLine );
        }
        out.close();
        in.close();
        client.close();
      }
    }
    catch( Exception e)
    {
      System.err.println( e );
      System.err.println( e.getMessage() );
    }
  }
}
