I have Hibernate3 app deployed Sun One App Server on 8.1EE. After a simple select query I am getting this error in the logs.



I am using antlr-2.7.2.jar file. I copied it to server_home/lib and also in server_home/lib/endorsed and also added the classpath-prefix in the domain.xml. After all this I still get a ClassNOtFoundException Can anyone please suggest a solution.

Thanks.

I am dealing with this same issue in Oracle 10g R3. In my case there is already an antlr.jar loaded elsewhere that ends up being found first on the classpath.

So what are the workarounds?

Well you can use the old query parser from Hibernate 2.1:



But I personally had trouble with this method... some of my queries weren't being produced correctly (as in the where clause would remain in hql for some reason). The other suggestion is to move hibernate and all dependant libraries to your servers boot classpath O.o I found all of this at http://www.hibernate.org/250.html in the BEA Weblogic section.

I'm still in the middle of solving this issue but just wanted to share what I found so far since I came across this post looking for answers myself.

The way I fixed it was to set the app server class-loader delegation to false.



You might try doing similar thing with Weblogic. Hope this will fix it.
