Hi - we are about to upgrade our production cluster from JBOSS AS 4.0.5 (config='default') to JBOSS AS 5.1(config=all). In the app we use code that uses the JGroups API to share data between cluster nodes. (Initially we wont be using any of the session replication or other shared cache featuires of the all configuration.)
Question: Will the JGroups version bundled with JBOSS 4.0.5 work with the JGroups version bundled with JBOSS AS 5.1? i.e. will our specific calls to JGroups API do the right thing and propagate the inter node messages correctly?
Yes, it will. But why don't you use the JGroups version shipped with 5.1 ? The API is the same, but we've fixed many gugs since 2.4.x (which is the version of JGroups shipped with AS 4.0.5) and increased perf a lot.
