In 3.2.6, you can do this through JMX by invoking the flush() method on the
appropriate EJB cache manager.

To clarify a bit, that it is role-based is a non sequitur; one could easily
imagine (and not-quite-so-easily implement) role based access rules based on
entity values.
The point is that the out-of-the-box EJB security model offers only control at
the bean class level -- that is, users in role
I notice that there is a lot of overhead involved in creating a new session
bean rocal or remote interface, and that XDoclet-generated Delegate classes
allow for caching the remote interface rather than re-aqcuiring it on each
request. This improves performance markedly. But I also notice
Ah, now I see what you're saying. Thanks.
I suppose there'd be no good way to cluster the injected abort state without
doing an mbean lookup on every call rather than injecting to a static field in
the interceptor from the jmx manager, though. That's dealable with, however,

Our application involves long-running (sometimes 3+ hours) transactions in some
circumstances. Occasionally, one of these is started accidentally, but there
is no obvious way to stop such a task once it's being executed inside the EJB
container. We could use a polled flag to signal a desired
The problem is that you don't just poll the flag once; you have to do it over
and over. To make it work in a cluster, the flag has to be implemented as a
clustered singleton mbean, which means that every lookup has to go through
JNDI, which has relatively high overhead.
In our app, there are
If I manipulate the security authentication cache via the JaasSecurityManagerService
mbean, am I dealing with only the cache on the current node, or cluster-wide? In
other words, if I (for example) flush the authentication cache, will it be flushed on
all machines in the cluster, or just on
Rather than embedding a reference to the image data, you need to return a properly
formed response containing the correct http headers, then the image data. Here's an
excerpted example from one of my servlets that does this:

I have an mbean which is a child of mx4j.AbstractDynamicMBean which depends on a
session bean. The deployment descriptor fragment below should cause it to not deploy
until the EJB container deploys:

Yes, OCI = thick in what I said above. We've seen this with both OCI and thin drivers.
Any further help from anyone, please? We can't upgrade to Oracle 10g until this is
resolved, and all my research on the issue has led nowhere.

My project builds and deploys as an ear properly in 3.2.4, but fails with a

We are considering migrating our JBoss 3.2.4-hosted app to 4.0. The available doc

making it difficult to estimate how long a
There are two kinds of users in my system. All users have the role User; some also
