You are probably already aware of the superficial 'why use ORM'  
arguments [1]. Beyond that, you should read through all the guides on  
the web site, probably skipping the JPA Guide at this time and also  
skipping the Remote Client Guide if you are not using ROP in your  

After you've done that, please come back to the list with any specific  
questions you have. There are lots of helpful people here who'll be  
happy to help you. Once you start using an ORM I guarantee you'll  
never want to scatter bits of SQL through your code ever again.
