/**
 * 

An EISConnectionSpec specifies how the * jakarta.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 *
