Is there how I could programmatically ask eclipselink to drop and create all tables?

问题

This helps in unit testing.

回答1:

The following should work for you:

ServerSession session = entityManager.unwrap(ServerSession.class);  
SchemaManager schemaManager = new SchemaManager(session);  
schemaManager.replaceDefaultTables(true, true);

回答2:

One way to do that is to execute the sql scripts eclipselink generates specifying:

      <property name="eclipselink.ddl-generation.output-mode" value="both"/>

in persistence.xml
