[JBoss-user] [Messaging, JMS JBossMQ] - UIL2: How to tune it to stop client disconnected errors?
We constantly get client disconnected exceptions when using messaging. We use the UIL2 connection layer on JBoss 3.2.1. When we run JBoss and the messaging client on the same machine we never get the error but when they run on different machines, after about an hour or two the clients get disconnected. The networks we run are terribly unresponsive and I believe that it is this that is causing the messaging to fail regularly. UIL2 has two settings PingPeriod and ReadTimeout which are set to 6 and 7 respectively. If I change PingPeriod to 6 then I can recreate the client disconnected error when running the client and JBoss locally. What is the best way to tune the two settings to stop the client disconnected errors? Can they both be set to 0 such that no disconnection checks are performed at all? Should I increase the ReadTimeout value to a huge number whilst leaving PingPeriod on 6? Help would be appreciated.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: UIL2: How to tune it to stop client disconnected errors?
An additional question: does the message listener thread, the one that invokes onMessage() also respond to server keep alive ping requests? The reason I ask is that I have a sneaking suspicion that if the thread that invokes onMessage() is tied up with processing lots of business logic then it is not in a position to respond to ping messages thereby making JBoss think that the client is not responding and then closing the connection.

[JBoss-user] [Messaging, JMS JBossMQ] - Binding topic connection to JNDI
We are facing an awkward scenario when sending JMS messages from within an EJB. We want to be able to cache a topic connection and reuse it rather than create a new one each time an EJB publishes a message. The connection factory seems to create a new physical connection each time rather than reusing them which eats up loads of resources - thats why we want to cache the connection. Obviously caching a connection in a static variable (the singleton pattern) is an obvious choice, but then this is subject to the vagaries of classloading by JBoss as to how many instances actually get created. Therefore, I wonder whether it is feasible to create a topic connection and bind in to JNDI? Are there any other options?

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Binding topic connection to JNDI
Thanks, sounds just the ticket. The FAQ entry is about accessing a remote connection pool, is there any differences in configuration if the EJBs that are accessing it local to the pool? Can one of those configuration changes be ditched?

[JBoss-user] [Security JAAS/JBoss] - JAAS trust implementation
Hi, Is anyone aware of an implementation of JAAS that provides a trust relationship between two applications? The purpose of this being that once a user is authenticated in one application they will by default be authenticated on any other trusted application. I would much rather opt for a proven solution were one available than develop one from the ground up; the danger of opening up a major security flaw by a developing a naive JAAS implementaton troubles me. Should there not be an implementation of JAAS with trust available, are you aware of an appropriate trust protocol that would map well to JAAS and J2EE to give me a head start?

[JBoss-user] [Security JAAS/JBoss] - Security context propagation between servers?
This is more in the realm of J2EE security than JBoss, but I would appreciate any guidance on it. How can a security context be propagated between two JBoss servers, or for that matter, any J2EE application server? I presume the answer lies in JAAS and custom login modules. Are there any off the shelf solutions? Does JBoss support it directly? I want to set up a trust relationship between two servers such that a succesful login in one server is trusted in the other by defualt. Note that these servers are not part of a cluster or share the same JVM. They are entirely indepenent. Please help!
