[Clustering] - Re: Non clustered Queue
by bstansberry＠jboss.com
That should be doable. What I described before was focused on the JMS server. And with it you have a server running on every node. The queue is independent; it can be deployed via deploy-hasingleton and that will work as long as there is a JMS server running on its node. Which there will be.
Hmm, big problem. The problem is to connect to that singleton queue, a remote client running would need to figure out which AS instance has the queue, and lookup the connection factory and queue from that AS. When you use the regular singleton JMS server approach, you just look things up using HA-JNDI and HA-JNDI finds the one node that has the connection factory and queue deployed. That won't work if you have a connection factory deployed everywhere. To get this to work you'd need to come up with some fancy integration of your own.

Hi,
I have a MDB with a very bad performance: the actual throughput is only 10 messages per second.
I need to improve it to 100 messages per second. How can I configure JBoss/MDB to archive this goal?
I've tried to tune the 'maxSession' property, without success.
My actual MDB configuration is:
@MessageDriven(activationConfig = {

[EJB 3.0 Users] - "Application Scope" in EJB project?
by mwx.dennis
In my project, Application clients access a JBoss AS via RMI.
Each client is assigned to a specific category, but only one client per category is allowed at the same time (so there may be mutliple clients connected to the AS simultaneously, but only one of each category).
How do I implement this? In a non-EJB environment I'd use synchronized login/logout methods which manage a flag for each category. But both synchronization and an application-like scope are unavailable in EJBs, right?
The obvious solution would be to have a database remember the login state and handle the concurrency issue. However, this seems a bit of an overkill and so far I do not need a database and I'd love to keep it like that.
Any input would be greatly appreciated!

[JBoss Cache Users] - Jboss AS 4.2 to 5.1.0 Caching problem O_o
by vergereau
Hello,
I'm a bit confuse with JBoss AS 5.1.0 concerning Caching.
I switch my application from JBoss AS 4.2 to 5.1.0 and I'm little surprise to see that doesn't work.
So I look the documentation on the http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/... but change nothing. I have a not classFound org.hibernate.cache.jbc2.JndiMultiplexedJBossCacheRegionFactory etc etc
Conf on Jboss 4.2.3
| <persistence-unit name="OracleTest">
|
| <jta-data-source>java:/oracleDSTest</jta-data-source>

| <property name="hibernate.cache.region_prefix" value="OracleTest"/>
| <property name="hibernate.show_sql" value="true" />
| </properties>
| </persistence-unit>
|
Anyone can help me to know how to set up caching on JBOSS 5.1.0 ?
Regards, Jérôme

[Security] - Re: Caller unauthorized on using a ejb3 statetlesssessionbea
by praenti
Using the Webauthentication does only have to be used from the interceptor instead of my own LoginFacade as I have seen. First of all is this correct?
So I hope I've moved to WebAuthetication in the correct way. I have seen a example how to implement a struts 1 filter. I have used the code to implement my struts 2 interceptor.
And this is the current error:
| 15:05:30,318 DEBUG [RealmBase] Username extern.michael.obster does NOT have role AdminUser
|
The login principal in the LoginModule gives me a mapping "extern.michael.obster" to "AdminUser", so this is in some way a discrepance, which I suppose that s.th. of the security context is lost (therefor I wanted to have "deeper" debugging, but I don't see a way how to do it because I cannot get a better acces into the JBossWebRealm.java).
This is my new JaasLoginInterceptor:
