Mark Done. There was a Weblogic page unused so added this and a link from Jboss Rules Tips and Tricks to this page.

I read from dev2dev and Weblogic bug tracker that Weblogic Jar has older version of antlr and only in 8.1.6 and 9.2 that they have fixed this problem. So the workaround is to put the jar in pre classpath before weblogic jar and it works. I am replying so that others can find it useful if they come across this. Change Request Number Description and Workaround or Solution Found In Fixed In CR236708 An Antlr conflict exists between Hibernate 3 or Jboss loading of antlr jar and WebLogic Server.

I remember with versions of hibernate, you had to put antlr at the front of the system classpath, or else use a locally scoped classloader. Probably teh same here (with the antlr 2.x file, not the 3.x one). On 12/15/06, Edson Tirelli <[EMAIL PROTECTED]> wrote: Uday, Some application servers also use antlr... I don't know about WebLogic. It may be worth to check if there is no jar conflict happening with another antlr/stringtemplate jar version that is eventually used by WebLogic. A simple way to test it would be to isolate the EAR classloader. In Jboss this is done in deployment descriptor, in WebSphere there is a configuration you set when deploying the EAR, but I don't know about WebLogic. Hope it helps.
