hi I know weblogic supports JMS API from version6.1 onward. Actually I do not have idea whether weblogic server can do all the thing that a messaging server like IBM Websphere MQ( formerly MQ Series) can do. I mean if one is creating a messaging application for that weblogic will act that as application server and messaging server or we need a separate messaging server for it. Thanx
Starting with J2EE 1.3, all full-fledged J2EE Application Server were required to have built-in JMS Providers. WebLogic actually has a very good JMS Provider (with clustering and failover support) so you can definitely write a JMS Application to run on WLS.
