I am wondering how to verify that Hibernate's L2 cache performs correctly. I have an application running on a cluster of JBoss 5 instances with JBoss Cache. Load testing would answer the question of performance.
But how to make sure that cluster related issues like the cache invalidation between nodes works like it should be?

Here is my configuration: Hibernate 3.3.1.GA, JBoss 5.1.0.GA, JBoss Cache 3.2.0.GA.
I'm doing Hibernate configuration as described here:

Hi all,
I have deployed the JBoss cahce service to my JBoss AS which is running remotely in a completely separate VM. I am now struggling to access the cache deployed to the AS. Does anybody have any suggestions?
Thanks In Advance

I'm trying to create a jboss-cache for data that is only relevant for a short period of time. After that time the data should be discarded and the respective memory freed.
The cache is organized like this:
/my_region
/session_1
/datanode_1
attribute1: value1
/datanode_2
attribute2: value2

I am evaluating various Java object distribution libraries (Terracotta, JCS, JBoss, Hazelcast ...) for an application server and I'm having trouble understanding their behavior on various axes.
My requirements for distributed objects are not many -- they boil down to one-to-one and one-to-many messaging. There's more, but for the rest w...
Is using JBoss Cache as distributed state repository a good idea?
Can JBoss Cache be applied in situation when you need the guarantee that each time you read something from repository you get the newest version of it? - and irrespective of which node in a cluster we consider?

We are using jboss cache as second level hibernate cache. It is configured to evict changed entities asyncronously. But this feature does not work for us. Some debugging revealed the root of the problem.
When treecache accessed, it adds itself as transaction listener. This is done by adding Synchronization to active transaction inside o...
I get the following exception:
org.jboss.cache.CacheException:

We use distributed JBoss cache for our web application (on Tomcat)
I have a strong feeling this is due to bad configuration, but not sure.
Edit (Correction):
We use version 3.0.0.GA of Jboss cache (core)

Hi, we have a horizontal cluster set up on JBoss 4.2. The session replication worked fine until we changed cache mode from REPL_ASYNC to REPL_SYNC to fix a issue. We started to see warning for some session failovers:

Our commercial application used to run on different application server and letely we started adjust it to run on JBoss server.
The problem is that that application runs JBoss cache and as part of the integration with this framework, the web-inf\lib contains the follwing jars:

Our application runs succesfully on Tomcat, Websphere and Weblogic and as part of it uses Jboss Cache version 3.1.0.G.
Now we would like adjust our app to run also in Jboss server environment.
Is there any Jboss server version that can co-exist working together with JBoss cache of this version (3.1)?

Hi all!
I'm using an extended persistence context (injected Entitymanager at SFSB) and have additionally set @TransactionManagement(value=TransactionManagementType.BEAN) for the SFSB to have full control over the UserTransaction.
The Transaction is controlled on client side where I start a lookup for the SFSBs containing a reference to...
I put a LinkedList into an aspectized Jboss Cache region.
I added 10K plain java object in that list but when I remove a object from the list, it spends too much time because of aopclassproxy methods.
Any idea on solve?
Note that only collection that implements List, Map and Set are aspectized by Jboss Cache API

Hi,
I'm using Jboss 4, hibenate, spring and treecache. As we have different environments, I would like to store the cluster information in a separated property file and reference to the content from the treecache xml file. I copied the treecache-optimistic.xml into
