Hi Raj,

A composite entity still holds good in JEE 5.0. Consider an entity User (mapped to the User table), which has among other properties a property called billingInfo (mapped to the billing table), preferences (mapped to the preferences table) etc. The Entity 'User' is a Composite Entity.

Thanks,
