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
//Here how to check hand shake is over or not ?
captureProcessor.verifyAndSendStartMsgs(context, session);
}
}
*State machine,IO handler and Filter Chain creation:*
StateMachine stateMachine =
StateMachineFactory.getInstance(IoHandlerTransition.class).create(
G10MinaClient.CONNECTED, new G10MinaClient(processor));
IoHandler ioHandler = new
StateMachineProxyBuilder().setStateContextLookup(
new IoSessionStateContextLookup(new StateContextFactory() {
@Override
public StateContext create() {
final G10StateContext stateContext = new
G10StateContext();
stateContext.setStartedTime(new Date());
LOG.info("G10StateContext initialized at:{}
",System.currentTimeMillis());
return stateContext;
}
})).create(IoHandler.class, stateMachine);
NioSocketConnector connector = new NioSocketConnector();
connector.getFilterChain().addLast("LoggingFilter",
G10CaptureService.loggingFilter);
connector.getFilterChain().addLast("codecFilter",
G10CaptureService.probeCodecFilter);
connector.getFilterChain().addLast("executorFilter",
G10CaptureService.executorFilter);
connector.getFilterChain().addLast("gpbMessageFilter",
G10CaptureService.gpbMessageFilter);
connector.getFilterChain().addLast("keepAliveFilter",
G10CaptureService.keepAliveFilter);
SslFilter sslFilter;
try {
SSLContext sslContext = TLSUtil.getSSLContext();
sslFilter = new CustomSslFilter(sslContext);
connector.getFilterChain().addFirst("sslFilter", sslFilter);
} catch (Exception e) {
e.printStackTrace();
LOG.error("Exception during creating SSL context..." +
XError.getStackTrace(e));
}
connector.setHandler(ioHandler);
