Then we will have to pack the three files into a JAR file. We look up the bean through a JNDI reference defined via a ejb-ref element. You may also run the example via the Ant build file:. MDB as a listener. The deployment descriptors for this bean are typical, except that you will have to add entries for the resource-ref element.

Listener pattern worker bean, from HelloWorkerBean.

This might be handy, but it is also dangerous since misspelled destinations may get you way wrong; and you will also have to tie the clients to a destination that is only temporarily available, as the destination will be destroyed if the MDB bean javax.ejb.messagedivencontext undeployed or redeployed.

Deploy the bean, for example, by packing it in a JAR file and copying it into javax.ejb.messagedrivencoontext JBoss deploy directory.

There are several other examples available with alternative configurations. It is then referenced from within the bean in the same manner you would reference a JDBC resource. What does work is the pluggability of server session pool factories. A bean with bean-managed transactions may have javax.ej.messagedrivencontext acknowledgement type of either Auto-acknowledge or Dups-ok-acknowledge.

Here it is one the for the queue bean: Typical conditions for doing javax.ejn.messagedrivencontext are:. Running the HelloListener example ant jms-hello-listener. This might be done in ejbCreate:. Let's write a working, but simplified, version of this pattern. You will have to add several JAR files to javxx.ejb.messagedrivencontext classpath to succeed at this. If one needs to write a provider-specific pool or do some customization of the existing one, it is possible to load it for a particular bean.

Message Driven Bean part in ejb-jar. The full-blown version of this is quite big, as it allows to configure the MDB container quite a bit.

The rest of the MDB container parts are basically agnostic regarding what kind of message system the container invoker uses. Doing this is really an advanced subject and it should probably be handled through contacts on the jboss-dev mailing list.

We also need to mar a jboss.

Developing the Message Driven Bean

javax.ejb.messagedrivencontedt Setting up the ServerSessionPool factory in jboss. The most important part of the descriptor is the specification of the destination. The deployment descriptors are in files HelloListener-ejb-jar. It is possible to avoid doing this, in which case the destination will then be automatically created and named after the bean; this may lead to quite surprising results, so it's not anything I recommend.

For the Message Driven Bean we have to decide whether it is a topic or not and what kind of transaction mode it should use. You would look it up this way:.

Invoke worker bean from the javax.ejb.messagfdrivencontext method. Lets look at it in smaller pieces. We choose the testTopic because it is always available in JBoss. Listener bean, from HelloListener.
