* The classes in this package represent EIS operations as threadsafe,
* reusable objects. This higher level of CCI abstraction depends on the
* lower-level abstraction in the <code>org.springframework.jca.cci.core</code> package.
* Exceptions thrown are as in the <code>org.springframework.dao</code> package,
* meaning that code using this package does not need to worry about error handling.
