I am trying to use Hibernate with a piece of server software called SmartFoxServer. It has it's own runtime environment, so I have little control over how that is set up. But when trying to use Hibernate EntityManager with it, I need to place the persistence.xml in a META-INF folder under the root folder (SFS2X). The problem is that the Ejb3Configuration.java file scans through all the files under that root, examining each .class file, I presume to see if it has annotations. This occurs around line 350-375 in the Ejb3Configuration.java file, (I'm using the 4.2.6 branch of Hibernate from GitHub)
There is a particular .class file that is part of SmartfoxServer hidden in a subfolder that causes this scanner to crash. I can't remove this file, as it is needed for SmartfoxServer. Is there anyway to stop hibernate from doing this recursive search? or way I can configure my environment to stop this? I've been reading through the EntityManager source code, but can't figure out if there is a way to stop it searching, although when it starts loading scanners from configuration, I kinda get lost.
Thanks for any help.
Here's the relevant part of the log file:
