We are migrating an application (Portal Application) from Hibernate 2 to Hibernate 3.
We tested our code in a standalone JUnit scenario, to make sure it works the way we intended. (And it does, in that context).
However, when the code is called from a Portlet, strange things start happening:

When we initialize Hibernate 3 we read the configuration with the followin sniplet of code:
[code]conf = new Configuration();
conf.configure("hibernate3.cfg.xml");
log.debug(conf.getProperties());[/code]

The output from the last line (the logging) clearly shows that the configuration was sucessfull; here is the output:

When we try to create a SessionFactory with the following code:
[code]if (sessionFactory == null) {
sessionFactory = conf.buildSessionFactory();
}[/code]
we get an exception (see above).

The interresting part is that some internal mechanism of Hibernate seems to create a violation.

This error does not seem to occur (or at least does not generate an error) when run under JUnit in a J2SE enironment (same JDK).

Any ideas?[/code]

I have investigated this further. The problem arises from the fact that we use both Hibernate2 and Hibernate3 code in the same application.
If the helper jar named 'cglib-asm.jar' (of Hibernate2) preceeds the 'cglib-2.1.jar' (of Hibernate3), then Hibernate2 portlets work (but not Hibernate3 portlets). And vice versa, of course, if the order of the jars is reversed.

Now, Hibernate2 and Hibernate3 are supposed to be able to co-exist. How can that be oachieved? I can't seem to find a solution!

Hi vainov,

I guess you could achieve this by configuring two different classloaders for each application. I'm still very confused about the WPS classloader hierachy, but it seems they are very flexibel.
I would be interesting for some information exchange about Hibernate on Hibernate in a WebSphere portal enviroment. So contact me if you would like to share experiences.

...why are you required to keep Hibernate 2 in the portlet project? Can't you migrate the entire thing to 3?
