Testing a Java Entity class outside of an Application Server (Using JUnit)

Question

I'm writing a few unit tests to test an entity class and I'm running these tests from within Eclipse.

In my persistence.xml I am referencing the JNDI name of a datasource that is set up in GlassFish.

When running the unit test from Eclipse, I get the following exception:

Exception Description: Cannot acquire data source [JNDI-NAME-FROM-APP-SERVER].

Could this be because I am not within the context of the appserver and if so, what would be the 'nicest' way to get around this?

Answer 1

Pass a properties Map to Persistence.createEntityManagerFactory(pu, properties) with your test database url and user/password.

Or have a separate persistence unit defined for Java SE testing.
