Hi, I am doing a udp chat with Java in Eclipse.
I have two classes Chat Client and Chat Server, the first of this one,contains the JFrame of what comes to be the chat screen, the main and a controller that manages connections to the server. The Chat Server has a Message and User.
The problem is that in the ChatClientController I have problems when implementing the functions: connecting ... disconnecting ...
I use a socket to send datagrams (messages)
If you can help me, I would be very grateful.
I can send you the code of the classes, if necessary.

Hola, estoy realizando un chat udp, cuento con dos clases Chat Client y Chat Server, el primero de ellos tengo el JFrame de lo que viene a ser la pantalla del chat, el main y un controller que gestiona las conexiones con el servidor. El Chat Server tiene un Message y User.
El problema es que en el ChatClientController tengo problemas a la hora de implementar las funciones de conectar...desconectar...utilizo un socket para mandar los datagramas(mensajes)
Si me podeis ayudar, estaría muy agradecido.
Puedo enviaros las clases por si es necesario.
