Hello,

Java version is 1.5.0_09. I am trying to connect from a Windows
machine to another Windows machine using sockets . Getting a socket
error for the following line. and throws EOFException

Socket s = null;
ObjectInputStream sin = null;
ObjectOutputStream sout = null;

s = new Socket( host, port );
sout = new ObjectOutputStream( s.getOutputStream() );

//write data to socket
sout.writeObject( req );
sout.flush();

InputStream is = s.getInputStream() );
sin = new ObjectInputStream( is ); // This line gives error

If I step into ObjectInputStream, I see:

public ObjectInputStream(InputStream in) throws IOException {
    verifySubclass();
    bin = new BlockDataInputStream(in);
    handles = new HandleTable(10);
    vlist = new ValidationList();
    enableOverride = false;
    readStreamHeader(); // This line gives error
    bin.setBlockDataMode(true);
}

However, the same code works when I try to connect from Linux(Red Hat
Enterprise Linux WS release 4 (Nahant Update 5)) to Windows. Turned
off Windows firewall but no luck.

On the Windows Server I am trying to connect to a server agent waiting
on port 2002 that helps me connect to Citrix running on that machine.
The agent runs as a Windows service.

What could be wrong here?
