title: mapping database link(drda) tables to entites in jpa
body: <p>I'm using a oracle thin driver to connect to my database.My database links to another db(DB2) with drda specification.My problem is that I can only view the local tables of my database and map them using jpa but I select from drda in sqldeveloper and it works so the problem is definitely with my application development.What do you think is missing?
  my application characteristics are as follows:
  IDE: MyEclipse 6.5
  Struts
  Spring 2.5/JPA
  Oracle 10g
  Tomcat 6.x
  Do I need to specify a jta-data-source? Right now I'm not using a data source?
  please help me</p>
