"Identifying session status before performing actions on it" To view the discussion, visit: http://community.jboss.org/message/557733#557733 -------------------------------------------------------------- Hello, I'm trying to see if I can implement a solution to a problem that I have, but if you think I'm looking in the wrong direction - please let me know. this is a description of my system: on the server side I have : 1. JBOSS 4.2.3.GA for java 6 2. with JBOSS Messaging 1.4.5.GA 3. and remoting 2.2.3.sp1 i have multiple clients that run as follows: 1. a process run using Java Service Wrapper by Tanuki 2. java code that connect to the server using JNDI lookup 3. CPP code activated through JNI. the clients receive message from the server and process them in the cpp code and we tracked a bug that we have to the fact that multiple clients are handling the same message. after some digging up it looks like the connection to client A is lost after it receives the message and starts handling it and so the JMS redelivers the message to client B. when client A tries to commit is response to the session we get an exception, but it's too late since the cpp part already committed it's work. *so what I wanted to know is if there is a way to query a session and see that it's still valid, or if you have an explanation as to why the connection is lost and what I need to do to prevent this*. Here are some of the messages we get - Server side: > 2010-08-16 16:10:35,468 DEBUG [org.jboss.remoting.ConnectionNotifier] > mailto:org.jboss.remoting.connectionnotif...@d77a85 >
