title: Setting default schema hibernate
body: <p>In eclipse I configured a database connection and I set up my JPA project to use it.
  In my entity classes, I get the following error:
  Schema "ROOT" cannot be resolved for table "XXX"</p>
  
  <p>In the project's JPA settings, there is a check box to "Override default schema from connection" with the schema set to "ROOT" by default.
  I can not change that because when I check the checkbox, the schema dropdown is empty.</p>
  
  <p>How do I force eclipse to use the correct schema? What is the correct schema name anyway? I only know the database / catalog name.</p>
