Hibernate version: 3.1.3

Full stack trace of any exception that occurs:

Name and version of the database you are using: Oracle 10gR2

Hello,

I get the following exception when trying to run a query on Oracle AS 10.1.3:

Code:

Everything seems to start up just fine, including session factory initialization, config init, etc..

Any ideas where to start? :)

This post http://forum.hibernate.org/viewtopic.php?t=961698&highlight=hqltoken gives the solution about replacing antlr.jar file

I replaced the .jar file (and even set in hibernate.properties to use the old query parser), rebooted, and am still getting the same stacktrace. Here's what I set in hibernate.properties:

Code:

hibernate.query.factory_class=org.hibernate.hql.ast.ASTQueryTranslatorFactory

What I found odd was that both antlr.jar's (one in the oc4j subdir, the other in toplink/jlib) had the exact same file size as the antlr.jar shipped with Hibernate 3.1.3. Any other ideas?

EDIT: I just realized that using "ASTQueryTranslator" is a little defeatist if my purpose was to use the old query parser :). Ahh well... will post another reply WHEN it works.

I still have no idea what's going on here. I've replaced all the antlr.jar's and am still getting this problem. I'm going to see if I can somehow force the application server to use the antlr.jar supplied in the .war. I did this with ejb-persistence.jar (The persistence jar shipped with the app server doesn't understand javax.persistence.Basic.optional()), but it doesn't seem to work with antlr.jar, assuming the problem is with this .jar. Still hunting around for other possibilities.

Thanks.

I downloaded and compiled antlr from the official website. Two possibilities:

1) Hibernate 3.1.3 ships with the wrong antlr.jar (pre-2.7.6)
2) Hibernate 3.1.3 ships with the CORRECT antlr, but I recently updated hibernate.jar without updating dependant libraries.

In any case, this works fine, even though the old antlr.jar is still in the application server's installation path. I checked the [x] Use Local Paths First or something in the deployment descriptor, which seems to force it to use my antlr.jar shipped in the .war.

Thanks!

There more likely scenario

3) Your application server have antlr.jar on its classpath and it is not proper isolated.

I had only heard about Weblogic doing this; did Oracle add some antlr dependent library lately ?

Toplink needs it. I was wrong about the libraries before, there is only one copy of antlr.jar in the installation folder, and it's the old version. I shipped a new antlr.jar in my WAR without touching the installed one and everything works fine.
