Thanks Emmanuel,I appreciate your quick response. I have one quick question
as you said "*finish_handshake method will prob-pagate the Session_secured
event to the IoHandler"* how to incorporate this code in my state machine
code ?
Currently we are on mina 2.2.1 code. Also i am sharing some sudo code too.
public class G10MinaClient {
private final G10CaptureProcessor captureProcessor;
public G10MinaClient(final G10CaptureProcessor captureProcessor) {
this.captureProcessor = captureProcessor;
}
/**
* This method is called when a new session is created.
*
* @param context Context for this state machine session.
* @param session The current IO session.
*/
@IoHandlerTransition(on = SESSION_CREATED, in = CONNECTED)
public void create(final G10StateContext context, final IoSession
session) {
captureProcessor.sessionCreated(context, session);
}
@IoHandlerTransition(on = SESSION_CLOSED, in = OPENED)
public void sessionClose(final G10StateContext context, final IoSession
session) {
captureProcessor.sessionClosed(context, session, false);
}
@IoHandlerTransition(on = SESSION_OPENED, in = CONNECTED)
public void connect(final G10StateContext context, final IoSession
session) {
//This will write data on to SSL socket
captureProcessor.verifyAndSendStartMsgs(context, session);
}
}
