[Security & JAAS/JBoss] - Re: JACC on the fly method permission changes not reflecting

by tpnaidu79

According to the JACC spec When I call commit() on a PolicyConfiguration object , the PolicyConfiguration for that contextId is set inService (i.e; made active). I am able to debug and inspect the object state before commit() is called and after it is called. The PolicyConfiguration is reflecting the changes made by me on the fly. However, the behaviour of the container is as per the previous rules given as system startup. I tried to go through the JBossAS source code to figure out what the container was doing on commit(). JBossAS has a class called JBossPolicyConfiguration which is the implementation of PolicyConfiguration interface as defined by the JACC spec. The commit() method in JBossPolicyConfiguration in turn calls the commit() method of a DelegatingPolicy object which in turn calls the commit() method of a ContextPolicy object. The commit() method of a contextPolicy object is an empty method, it has no refresh or anything... in this case how does the container become aware of on the fly ejb method permission changes? The code of what I was trying to explain above is as follows: JBossPolicyConfiguration code: public void commit() throws PolicyContextException { if( trace ) log.trace("commit"); validateState("commit"); policy.commit(contextID); // policy is a DelegatingPolicy object } DelegatingPolicy code: public void commit(String contextID) throws PolicyContextException { ContextPolicy policy = getContextPolicy(contextID); openPolicies.remove(contextID); activePolicies.put(contextID, policy); policy.commit(); } ContextPolicy code: void commit() throws PolicyContextException { } I guess I am missing something here can anyone please help me.

[EJB 3.0] - persistent object modification by different threads safe?

by ppphoenixxx

Hi, according to EJB3-Specs a single EntityManager object isn't thread-safe, so the same EntityManager shouldn't be used by different threads: but what about obtaining a set of persistent objects, applying some changes on them in a *different* thread, where no EntityManager methods are called or used? Well it works, right out of the box: no EntityManager.clear or merge calls needed in the "original" thread - but I have no idea if this is safe, supposed to work or should be avoided at all costs: I only know that I spare myself a little work by not going the usual way to get me another session bean and obtain an entity manager there. To give you some details about the application I am writing: Its a standard EJB3 one, with some persistent objects and a built in callback-server which listens in a different thread on a specific network port for connections and should do some persistent operations upon a callback-connection from a client. Thanks for any input!

[Clustering/JBoss] - Re: Session is getting replicated on JBoss-4.0.1 only one ti

by bstansberry＠jboss.com

Thanks, much clearer :) What you're doing sounds fine, and the behavior you report sounds like a bug. So I searched JIRA for 4.0.1 bugs and found http://jira.jboss.com/jira/browse/JBAS-60. That would cause the symptom you report -- once the session is active on cluster A the manager is unaware of replication traffic from the other node. It was fixed for 4.0.2.
