I have 2 schemes in the database, and I want to create an application that uses data from the other schema. My question , can I use many database schemes' connection in one application? I know that each 'ear' file must have one connection. so how could I create an application with 2 connections?!

You need to use composite persistence unit for this purpose. But this is slightly tough to handle, specially when anyone is a beginner. Please check these links for help:
