I'm wondering if anyone has tried to install hibernate in the Java jre/lib/ext directory and whether that causes any problems?

I know in the manual it says not to install the libraries in the shared lib directory when you are using Tomcat. To me it seems kind of excessive to have to bundle the libraries with each webapp if you have several webapps that all use hibernate.

One of the issues that I've run into is that I eventually run out of memory after I have reloaded my webapp several times. I'm thinking the problem might be the fact that it's reloading the hibernate libraries each time I reload my webapp. I've been using hibernate-3.0beta1 and hibernate-annotations-3.0alpha1 and a few different versions of Tomcat 5.5.x.

It would be nice if someone who can reproduce this would actually use a profiler and find out what the problem really is.

I think JDK 5.0 has new profiling capabilities. I wonder if I could use that?

I am using ThreadLocals of my own. Don't know whether that's the problem...
If I remember correctly, the problem was occuring before I started using ThreadLocals.

I wonder why that would make a different anyways...

Yes, this directory must be empty on servers.

Why is that though?

One issue that I ran into is that it wasn't able to find my hibernate.properties file, presumably because hibernate was loaded by another class loader, but, I'm wondering if I specify the properties using the API, if it will work OK in that case.
