Re: socket communication: socket doesn't connect

I am trying to establish socket communication between my C++ and Java
program.

I bring up the Java program from the C++ program with ShellExecEx.

Then I start in the Java program with:
int port = 3000;
int rev = 1;
InetAddress address = InetAddress.getLocalHost();
Client client = new Client(port, address, rev);
int[] ints = new int[1];
ints[0] = 1;
client.send_ints(ints, 1);
client.closesocket();
using my Java Client class.

Then I continue in my C++ program with:
int port = 3000;
Server* server = new Server(port);
server->connectServer();
using my C++ Server class.

It looks like the server gets constructed properly and the connectServer
method calls the connect method from WinSock.h, which I have included
(and
its library WSock32.Lib is at Additional Dependences in the Input of the
Linker).

Why does this connect method from WinSock.h return - 1?

Just in case, here is the constructor of my Java Client class:
public Client(int p, InetAddress address, int rev) throws IOException,
IllegalArgumentException
{
   port = p;

   try
   {
      sock = new Socket(address, port);
      input = new BufferedInputStream(sock.getInputStream(), BUFFSIZE);
      output = new BufferedOutputStream(sock.getOutputStream(),
BUFFSIZE);
   }
   catch (IOException e)
   {
   }
   catch (IllegalArgumentException ie)
   {
   }

   buff = new byte[BUFFSIZE];
   data = new byte[BUFFSIZE];

   output.write(rev);
   output.flush();
}

and the constructor of my C++ Server class:
Server::Server(int p) throw (string)
{
   WSAData wsaData;
   if(WSAStartup(MAKEWORD(1,1),&wsaData) != 0)
   {
      throw string("help!");
   }

   port = p;

   if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1)
   {
      throw string("help!");
   }

   my_addr.sin_family = AF_INET;
   my_addr.sin_port = htons(port);
   my_addr.sin_addr.s_addr = INADDR_ANY;

   if (bind(sockfd, (struct sockaddr *)&my_addr, sizeof(struct sockaddr))
==
-1)
   {
      throw string("help!");
   }

   if (listen(sockfd, BACKLOG) == -1)
   {
      throw string("help!");
   }
}

Thanks for your time looking at this!
