Hi folks,

I've been reading the forum and appreciate all of the useful information here, which has helped me tremendously. I'm running WebLogic 7.0 sp2 and have gotten Hibernate 3 to run successfully there. I went through the antlr issue described here on the forum, and was able to put Hibernate's antlr version in the weblogic classpath. However, there seems to be problem parsing queries named in the mapping files.

The error I'm getting is java.lang.NoSuchFieldError: tokenTypeToASTClassMap. I've searched extensively and can't find anything on this related to Hibernate. Also the source code for the offending class (org.hibernate.hql.antlr.HqlBaseParser) doesn't seem to be available in the Hibernate distribution or the online CVS browser.

The only thing I can figure is it has something to do with the version of antlr, but since I have antlr-2.7.5H3.jar in the weblogic classpath ahead of weblogic.jar, I'm at a loss to understand why. Any help would be appreciated!

Hibernate version: Hibernate 3.0.3

Name and version of the database you are using: Oracle8i Enterprise Edition Release 8.1.7.4.0

I'm new with hibernate but I saw the same problem that you did today and just wanted to pipe up in case I can help.

I was getting a similar exception and tries googling for some help. I learned about the need for the proper version of antlr in the classpath and in my case that solved the problem. I moved the antlr version provided w/hibernate (3.0.5 in my case) to the top of my classpath (as opposed to the bottom) and all was well after that.

I realize you've tried this solution.

Do you possibly have a "bad" version of antlr in your classpath, for example in your jre's lib/ext dir?

Perhaps you can figure out where the JVM is locating the antlr classes?

Perhaps you could try hibernate 3.0.5?

Good luck!

John,

thanks alot for your reply. From what you've said and what I've seen on Google, it does sound like an antlr version problem. Frustrating, because I can't seem to track it down. I won't be able to change Hibernate versions because another end of the application is using Hibernate (but not Weblogic) and so we need to be consistent in our versions. In fact it is that team's mapping files which I am reusing and having the problems with. Anyway, your suggestions are definitely helpful!

read the migration guide - has a special section for weblogic

Yes ... I had already read that as well as other resources and discussions, and understand the issues described there. The migration guide does not address the particular problem I'm seeing.

did you try and do what is told about weblogic ?

(adding antlr in weblogics lib path ?)
