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 org.springframework.jca.cci.core package. Exceptions thrown are as in the org.springframework.dao package, meaning that code using this package does not need to worry about error handling.
