Can mapping files (*.hbm.xml) sit in a jar different from the one containing mapped classes?

I have a library of business objects that is used in two different environments: one running H3 and the other still on H2. I want to use the same business jar in both environments and only drop in the appropriate mappings jar.

This setup has worked for me in a desktop application, but when I try the same under Tomcat, mapping files cannot be found. Is there something about Tomcat's classloaders that may prevent Hibernate from locating the xml files?


Thanks

Hibernate version:
3.0.x

If you use the "resource" attribute then the mapping files are located via the Java resource mechanism, so these files are located as long as they are in the classpath. So I tink it should work...

niqueco, i'm not sure which "'resource' attribute" you are referring to. Could you elaborate?

thanks

I was referring to the mapping element of hibernate.cfg.xml, but this is not useful to you, because you need a differente configuration for that old hibernate... =)

Anyway, everything is located with resources... I don't know what are you wanting to do exactily, but separating the .class from the mappings should make no difference.
