[openjms-developer] JCA Support + Hierarchial Topics

Discussion:

Hello,
I would be interested in contributing to OpenJMS. :-) I been
looking at the Apache Geronimo project and i seems that if OpenJMS
had some JCA support it would both to play nicely :-). So I'm here
to give that a stab! Deadlines are a bit crazy at work ATM
(nothing new) so it will be a few weeks until i get to coding it.
I would like to take a good look around the OpenJMS code before i
get into coding anyway.

On another note, does OpenJMS support hierarchal topics for Pub/Sub i have
had a look around the site and there seems to be no word of it. Any plans
in the pipe for developing support for it ?
Regards,

Cool. There was another post on the geronimo list by
someone interested in integrating OpenJMS - I'll try and
find it and forward it on. (Faster if you collaborate rather
than duplicate effort :)

OpenJMS does support heirarchical topics, although as you've
found, its poorly documented. I'll accept patches :)

You can register hierarchical topics in openjms.xml as follows:

<AdministeredDestinations>
<AdministeredTopic name="parent.child.a"/>
<AdministeredTopic name="parent.child.b"/>
<AdministeredTopic name="parent.child.c"/>
</AdministeredDestinations>

And in your code, construct a wildcarded topic:
Topic topic = session.createTopic("parent.child.**");

A TopicSubscriber using the above will receive messages
published to any of parent.child.a, parent.child.b, or
parent.child.c.

Hi Brent,
As you have read i am planning to add some JCA support to OpenJMS,
while this is not the exact plan you had posted on geronimo-dev i
think it could a nice solution to the problem.

There seems to be a lot of support for adding JCA support to geronimo, so
i will concentrate my efforts on the OpenJMS side of the equation. Would
you be up for joining in on this side too?

Regards,
Ed
