Node locking and concurrency is important to retain data integrity. Do you
have a high percentage of writes? If so, then a caching library is NOT what
you need. (think about it! :)
If you want to use JBoss Cache as a distributed in-memory database, then I'd
recommend using pessimistic locki
Thank you! :-)

I tried to change this.
I now have major problem with node locking errors.
It seems it cannot cope with highfrequency updates?
I have an Ojbect (ImportTracker) that holds multiple objects (BatchTracker).
The ImportTracker holds all the BatchTrackers, the BatchTracker holds data
about the imp
Here's your problem:
CacheHelper.getImportCache().get(nodename).put("importTracker", tracker);
Use:
CacheHelper.getImportCache().put(nodename, "importTracker", tracker);
Do the same anywhere else you have the same kind of thing going on.
The 1.x "public Node get(Fqn)" method was a bad idea and
I used fisheeye recommended-config.xml and modified it for my purposes.
I have checked out alternative configurations with evictionrules etc, but they
still does not trigger the store interceptor, thus leaving the persistant state
and the in-memory state inconsistent with eachother.
I am stil
I didn't really dig into your specific issue, but I do have some general advice.
Regarding persistence, there are some bundled configurations that use cache
loaders. You can try to use these as a "sanity check". These configurations are
unit tested and should work. Check out the unit tests for
Hmm.. no replies :-)
I suppose that this could be a bug in jboss as aop implementation that does not
trigger interceptor as it should.
It could also be that treecache bug where the pointcut definition is not
correct.
Then of course it could be me that has used treecache in the wrong way... (O
My current workaround:

| {
| logDebug("storeTracker() - start");

| try
| {
| if (useTreeCache)
| {
| logDebug("ImportTracker - PUT");
| boolean transactionActive = false
