Hibernate error

Question

Hi everyone!
We're currently trying to get Hibernate to work on NW J2EE 6.40. We deployed the jars mentioned in [Hibernate on SAP NetWeaver (1st version)|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/14f55178-0801-0010-0bac-974ed17e51d3] successfully. While it seems to be somewhat working - at least we're seeing hibernate error messages - we run across a NPE in
AbstractEntityTuplizer.createProxy()
when calling
session.load()
In [Hibernate Issues HHH-1365|http://opensource.atlassian.com/projects/hibernate/browse/HHH-1365] this is said to happen when running Hibernate 3.1.3 against a signed JAR. Since I did not see any posting related to this error under NetWeaver, I think that the problem is caused by me using a wrong Hibernate version (we try to use Hibernate 3.1.3) with J2EE 6.40.
I did not find any version hint fpr Hibernate 3 in the document version linked above, so I used the version mentioned in [Hibernate on SAP NetWeaver (2nd version)|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/bf0d57db-0c01-0010-6fa3-83503981eed4], but this version deals with NW 2004s / J2EE 7.0. The other jar's versions are identical.
Can anyone confirm that I may be using the wrong Hibernate version and/or tell me which version of Hibernate3.jar I'd have to deploy to avoid this ?

Answer 1

O.k., for everyone who might be interested in this topic: We resolved the problem by putting the jars for
hibernate 3.2.6.ga
antlr 2.7.6
asm
cglib 2.1.3
commons-collections 2.1.1
commons-logging 1.0.4
dom4j 1.6.1
ehcache 1.2.3
jta
into a DC and exposing all jars in both assembly and compilation public part.
