Hello Jon; Thanks for the email. Sorry; it is a bit much for me to jot-out in an email and I use my own (very similar) change notification infrastructure rather than the system in PW. You need to include the following JAR files in the WOA for use with ActiveMQ; activemq-core-5.

I would avoid using the JMS change sync stuff and move to the project wonder jgroups version. We just migrated away from the JMS stuff - it caused us a lot of hanging issues under load. OpenJMS is a dead project. Use ActiveMQ Dov Rosenberg On 1/6/09 2:18 PM, "Andrew Lindesay" wrote: > Hello

We have been using a modified version of the ERChangeNotificationJMS framework for a couple of years with pretty good success. We have recently started running into problems as we have been scaling our app to larger sets of data. We are using OpenJMS and have experienced some unstable behaviors - u

OpenJMS is pretty flaky. I'd recommend one of the other Synchronizers (ERXSimpleMutliCast or ERJGroups) Cheers, Anjo Am 23.10.2007 um 17:20 schrieb Gino Pacitti: Hi All Can I use the ERChangeNotificationJMS to synchronize instances from 2 apps? They both share the same database and I ne
