I have four jar files related with hibernate in defualt/lib folder. That are
1) hibernate3.jar
2) hibernate-annotations.jar
3) hibernate-entitymanager.jar
4) boss-hibernate.jar

Still what is the issue, i am not able to understand. Please Help me to find a solution.

Thanks
Rasa

The package names for Hibernate have changed - they are now org.hibernate instead of net.sf.hibernate. You will have to modify your applications and recompile them.

Optionally, you could try defining a classloader repository and include the old hibernate JAR files with your app. See http://jboss.org/community/wiki/ClassLoadingConfiguration

Ok. Yes my application is using higernate2 any way i dnt have any plan to change my hibernate version. So i deleted the existing version 3 from the lib direcory and then copied the version 2. Is that will make any other issue.

Thanks and Regards
Rasa.

Do not replace the hibernate JAR file in the lib directory. I already told you how you could avoid changing your app - use a classloader repository.

[rasa]

ok fine. Now i copied the 4 jar files back to lib direcotry.

and as per the given link i am going to do like this in my newly created jboss-app.xml file.

<jboss-app>
 <loader-repository>
 com.example:archive=hibernate2.jar
 </loader-repository>
<loader-repository>
 com.example:archive=xxx.jar
 </loader-repository>
</jboss-app>

Hope i am right?

I need hibernate2 in my application. Same way i have to solve other version issues also.

Thanks and Regards
Rasa

Why are non-jca things being discussed here?

Why are non-jca things being discussed here?

For one, I don't often look at which forum a question is in when i answer it (comes from answering the questions as they come into my inbox).

Second, I doubt that most JBoss AS users could tell the difference between a question that is appropriate for this forum, or that should go into one of the other forums - JCA is not a very clear category, especially since JCA is used to connect to a multitude of things, including databases.

rasa - did you try it? Did it work? (I think you want to declare only one loader repository, though.)
