/**
* An EISConnectionSpec specifies how the
* javax.resource.cci.Connection is accessed. There are three ways
* to connect to an EIS datasource through JCA:
*
* - Provide a JNDI name to the ConnectionFactory and use the default
* getConnection
*
- Provide a JNDI name to the ConnectionFactory, and a driver specific
* ConnectionSpec to pass to the getConnection
*
- Connect in a non-managed way directly to the driver specific
* ConnectionFactory
