This is code extract from MINA example. Please get the code from there. You get the Session reference once your connection is complete

ops, I had losting a slf4j-api library.

The Server is starting correctly but the client is a Nightmare…
Just a few question:
The code in the top is for Client or for the ClientHandler? Where is the main function for client?
And where I can define the Object session?

thanks

Please set classpath as per this page http://mina.apache.org/mina-v20-quick-start-guide.html
Its not a problem. You can find the code with MINA distribution

hi… at the start, sorry for my terrible english…

I must implement a chat with apache mina for a university project but I don’t understand nothing about Mina. I’m using Eclipse and it produces always the exception

“Exception in thread “main” java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

Please, could you send some complete sample TCP source code using apache MINA? because with the published code I can do anything…

thank you

Shiva, the code is complete, you just to glue this function together in main. I have removed unnecessary code, to keep posts simple. So, in main you call connect() and the call send data. Prepare the data u need to send.

Its that simple
