Re: JMS Clustering in Geronimo v1
I see one short criticalcommingon Geronimo at the moment is we haven't defined what can and what we have todo in terms of clustering. I am glad you started the thread on JMS clustering, so some of the questions will be addressed There is no documentation out there what has been done or needs to be done. Insteadof complainingI am planning to fill the gap with the help ofHernan, but would need help and input. We did disscuss some issues with HA-JNDI, there is lot of disscussions on Web clustering, but other than that there is no direction or disscussion. This will confuse a lot of the end-users. Clustering is pretty darn important in any production-level deployment and if we don't give a clear idea to the community about where we stand or atleast the fact that we have recognized where we need to work or some sort of RoadMap the endusers will be very confused about the whole issue.

Re: JMS Clustering in Geronimo v1
My understanding is that ActiveMQ has full-featured clustering functionality. I am sure that James will elaborate.

Today the simplest option is just to run the ActiveMQ broker outside of Geronimo and just use the JMS client / JMS Resource Adapter / RAR inside Geronimo. However as we integrate the latest 4.x of ActiveMQ into Geronimo we hope to address this to make things fully configurable from inside Geronimo James --- http://radio.weblogs.com/0112098/ ___ To help you stay safe and secure online, we've developed the all new Yahoo!
