In MINA 1.1.0 source code there are too much commets exist such as; public Set<IoSession> getManagedSessions( SocketAddress serviceAddress )
Eclipse gives error for <IoSession> tooken. Would you pls. advice me to have a clean source code? Thanks. ---------- Murat OZDEMiR -----Original Message----- From: Murat OZDEMiR [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 05, 2007 11:31 AM To: '[email protected]' Subject: RE: Help!

Thank you for posting your source code. I couldn't find a particular problem there. Due to the characteristic of the problem, I'd like to suggest you to try the following things: 1) Provide us the full thread dump when the server is having a problem. 2) Modify DatagramAcceptorDelegate (in org.apache.mina.transport.socket.nio.support). 2a) Change selector.select() to selector.select(1000); (this will check if the selector is waken up correctly) 2b) Print out some debug messages in DatagramAcceptorDelegate.flush(DatagramSessionImpl) and around selector.select(). 3) Provide us minimal client/server implementation that reproduces the problem.
