Hi all,

The following stacktrace is not a problem with Hibernate, but with weblogic 10Gr3 using hibernate 3.2.6. It screams classpath/class loader issue to me and I have tried everything I can think of.

I am deploying an EAR that contains one WAR.

As the link http://forum.springsource.org/archive/i ... 26594.html suggests, I have checked to make sure there is only one hibernate jar in the classpath. Weblogic can't find the hibernate classes if I remove it from my app.ear/app.war/WEB-INF/lib. I have tried putting the hibernate JAR in
<domain name>/lib in my weblogic domain directory and that doesn't help. There is nothing on the Weblogic OTN user groups discussing this error (you need to pay extra above the weblogic licensing fee to post there).

Adding org.hibernate.* to prefer-application-packages of the weblogic-application descriptor doesn't help.

If anyone has seen anything like this with Weblogic and has any suggestions I'd love to hear them.
