Hi,

I've been looking for a way to differentiate the log output of multiple SessionFactory instances in a JBoss server.

More specifically; I have multiple SessionFactory instances bound to JNDI in a single JBoss server instance. I want to be able to set the log level to DEBUG for SessionFactory 1 and all the Session's built using it, but keep the log level as INFO for the rest (Keeping every mapped class in a single SessionFactory is not an option for my case).

However, looking at the code of SessionFactoryImpl, the logger is declared as:
private static final Log log = LogFactory.getLog(SessionFactoryImpl.class);

which uses a logger named after the class name. And declared final.

So, I assume all hibernate log output should use the same Logger, hence no ability to differentiate the output.

Is there any way to overcome this limitation ?

Thanks,

you could alter source a bit , for example make the log non static and provide a setter for the log, then in the code that creates those factories the log name can be specified.

Thanks. That's what I thought in case there's no other way without modifying the source. (I've been thinking of some methods based on using different classloaders.)
I wonder how people have been living with this, because I think parametric log output modification/redirection is crucial in a managed environment.

I guess I'll make a patch and submit to hibernate developers.

I would not recomment trying to mess with classloaders, it might have nasty side effects.
