[keycloak-dev] Unable to connect to an external datasource for a protocol mapper

I'm a little inexperienced when it comes to Java EE.  So let me apoligize
because I'm guessing this will be a small setup mistake.  I've setup
databases for applications but I'm having a really tough time with
connecting to for a Keycloak module.  The database exists separate from
Keycloak's user db and a LDAP/AD because other services for our application
need to access the claims database through rabbitmq and rest services.

I'm able to setup a datasource in Wildfly and verify it can connect to the
database.  So I know the connection info is good.  The module successfully
deploys to Keycloak.  When the Protocol Mapper is ran,  I only try checking
the nullity of the EntityManager that should be injected as well as one
that gets created from the PU by hand.  The injected em is null and the one
created on a spot throws an exception about being unable to find the
persistence.xml file.

What are some good troubleshooting techniques for developing in Keycloak?
Is it more appropriate to turn up the hibernate logger in Keycloak or
Wildfly?

Could someone take a look at an exmple give me some advice?
A code  example is at https://github.com/tlann/tokenEnhancer.git

The deployment log and exception are as follows

Thanks,
Thomas
