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 :
- JBOSS 4.2.3.GA for java 6
- with JBOSS Messaging 1.4.5.GA
- and remoting 2.2.3.sp1
i have multiple clients that run as follows:
- a process run using Java Service Wrapper by Tanuki
- java code that connect to the server using JNDI lookup
- 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 -
