I have a jar(common.jar) file which will be used by all the J2EE applications. I put it under WebSphere\AppServer\lib\ext folder. The hibernate.cfg.xml is in common.jar.

If we have J2EE application which also use hibernate, it has its own hibernate.cfg.xml. Will hibernate.cfg.xml in common.jar affect hibernate.cfg.xml in the J2EE application? Thanks.

It depends on the classloading feature of websphere. Also if you know the order in which websphere loads the classes that may be helpful. If websphere loads the jar under ext first then you may be fine. In case if the ext and jar under J2EE app also loads at the same time you may experience SessionFactoryObjectNotFound exception because of clash between two config files.

Can't you have the hibernate cfg in one jar which is common for all J2EE applications running in websphere? Can't you place it directly under lib of app server?

Thanks for your reply,Sun.

No, we don't want to test all applications since we touch the hibernate cfg file.

If I do like this, I have the similar question: will the hibernate cfg file under lib of app server affect the hibernate cfg file under J2EE applications?
