Java Server Client C problem

[Jelle87]

I'm having a problem with my server and client, as a result he seems to bind evything and so... But I can't send from my client or receive... Don't seem to find the wrong thing myself...
Can anyone please help

This is the Java

public class startServer {
public static void main(String[] args) {
String clientSentence;
String capitalizedSentence;
ServerSocket welcomeSocket = null;
try {
welcomeSocket = new ServerSocket(6789);
System.out.println("Server running.");

while(true) {
Socket connectionSocket = null;
connectionSocket = welcomeSocket.accept();
BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream( )));
DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream( ));

System.out.println("receive...");
outToClient.writeBytes("test");
clientSentence = inFromClient.readLine();

if(clientSentence.startsWith("TOTAAL_BEDRAG:")) { // eerste deel = 14, tweede 8
capitalizedSentence = clientSentence.substring(14).toUpperCase() + "\n";
System.out.println("VALID MESSAGE: \"" + clientSentence + "\"");
outToClient.writeBytes(capitalizedSentence);
} else {
System.out.println("INVALID MESSAGE: \"" + clientSentence + "\"");
outToClient.writeBytes("\n");
}
}
} catch (IOException e) {
System.out.println("Error: Java");
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
//System.out.println("Received: " + clientSentence);

//outToClient.writeBytes(capitalizedSentence);
}
}

This is the Client

If I run the server, and then the client, I get WSA error 10057.. But don't find relevant information about this.
