Description
The OpenEJBContainer in Arquillian only starts a couple basic services with OpenEJB without any configuration or addition of other services and resource adapters. Without Arquillian, one would use a jndi.properties file, for instance, and then create the initial context which would start OpenEJB with all of its configuration options. Without configuration, Arquillian tests cannot be used in real environments.
As an example, consider the arquillian-samples/jpalab. When Maven is run with the default profile for OpenEJB and OpenJPA, the following log output is produced (excerpt with only OpenEJB startup lines):

The key items to look at is that only a "Default JDBC Database" data source and its unmanaged complement are created. There is no testDatabase data source being defined, as specified in the jndi.properties file. Also note that the persistence unit was automatically modified to point to the default data source since OpenEJB could not find any testDatabase source.
I'll show what the log should look like shortly. I have this fixed already and in use on a project.

This related issue might be solved. It is now possible to have an XML configuration file for OpenEJB; however, the file must be specified by a property in jndi.properties (openejb.config.file or something similar).

added a comment - pushed upstream master I made a mistake on the config property name for the openejb.xml file. I need to fix this and add to the test so that both configurations are verified.

The property name was changed and additional testing provided to make use of the XML configuration file for OpenEJB. Code is located in same Github branch.

Still need to add something to documentation, but the fix basically appears thus far as at git://github.com/drallen/arquillian.git.
The log output for comparison should appear as:

This time, a third service is configured during startup for the testDatabase, the data source defined in the jndi.properties file. Also there is only one line regarding adjusting the persistence unit. This is for the unmanaged data source connection which was not specified in jndi.properties nor in the persistence.xml file, thus OpenEJB uses defaults. The important thing is that the JTA data source is now changed.
One final note is that OpenEJB 3.1.4 needs to be used now. The class cast exception many have seen since October somehow now propagates through the Arquillian container and causes the tests to fail with the fix for this bug. The exception was fixed in 3.1.4, so it's no longer a problem.
