Transactions in an MBean service using TreeCacheAop

[andyd]

Guys,
What is the correct way to get a transaction set up for use against a TreeCacheAop instance when in an MBean?

I have tried

1 mgr = DummyTransactionManager.getInstance();
2 ObjectName cacheService = new ObjectName("btgs.bgan:service=TreeCacheAop");
3 server = MBeanServerLocator.locate();
4 tree = (TreeCacheAopIfc)MBeanServerInvocationHandler.newProxyInstance(server, cacheService,TreeCacheAopIfc.class,false);


this throws a NameAlreadyBoundException at 4 and the rollback doesn't seem to work when I try and roll back after a field change of a serialised object stored in the cache.

Do you still have to aspectize pojos if they are Serializable? Could this be my problem?

I have seen the exampe BSHs, but I'm not sure that that is the answer.



Thanks,
Andy.

Just found this

Looks promising...

I can relate to the late night posting comment :-(

Ok, so know I'm using the right interface, but no joy on rolling back changes to the field in the pojo I'm caching. Does this need to be aspectised to work in a transaction?

Thanks.

Yes, the pojo must be aspectized. If it isn't the cache can't intercept changes to its internal fields.

Ok, thanks Brian.
I'll work on that one.
