Contextual Sessions in Hibernate

Somehow I missed this new feature in Hibernate 3.0

Contextual sessions means that you can ask the SessionFactory for the current session. It will then return the session associated with your current JTA transaction. Of course, you need to have a JTA transaction, but that’s not that big a deal. (For example, transactions with EJBs are JTA based)

This means that you don’t need to pass the current session around in order to get access to it; you simply ask the SessionFactory. Of course, you need to get at the session factory – that can be done via JNDI very easily. And, of course, the session factory is threadsafe, whereas the session isn’t.

My name is Robert Watkins. I am a software developer and have been for over 20 years now. I currently work for people, but my opinions here are in no way endorsed by them (which is cool; their opinions aren’t endorsed by me either). My main professional interests are in Java development, using Agile methods, with a historical focus on building web based applications. I’m also a Mac-fan and love my iPhone, which I’m currently learning how to code for. I live and work in Brisbane, Australia, but I grew up in the Northern Territory, and still find Brisbane too cold (after 22 years here). I’m married, with two children and one cat. My politics are socialist in tendency, my religious affiliation is atheist (aka “none of the above”), my attitude is condescending and my moral standing is lying down.
