Hibernate - lazy vs. eager loading

Hey all--

I'm new to this forum (and actually to JavaRanch in general)! Any best practices/etiquette advice is always welcome.

My group is using Hibernate for our current project. This is my first time using the tool and I have some questions regarding lazy vs. eager loading.

In the hbm files, there is a 'lazy' attribute which allows one to specify if a related collection should be eagerly loaded or not. There is also a 'batch-size' attribute which defaults to 1. How is this attribute used?

Thanks,
RishPan

lazy=true improves performance: if some class has a bag/set, their elements are loaded only after you make an explicit call to MyObject.mySet

but hibernate site explains it here and here

i'd recommend you browse hibernate docs (they come with download): quite an excelent aid!
