How can I expire all objects in the Hibernate cache?

In our application there is a separate non-java program that also inserts records in our database (in addition to our Java program). The result is that the Hibernate cache and the database are out of sync (and often Hibernate overwrites changed records). What is the best way to completely reset the Hibernate cache (both session and second-level)?

I guess I'm looking for something like evictAll().

Another question: what is a "roleName" and where do I define it? I'm trying to use the evictCollection(String roleName) of SessionFactory. Is it in the mapping files?

Thanks

From section 12.3 in the reference:

To completely evict all objects from the session cache, call Session.clear()
