Re: AW: jca adapter for (MySQL)DB

It is important to separate out SPIs and APIs to understand the relationship
between JDBC and Connectors.

JDBC is primarily an API, and Connectors is primarily an SPI. CCI is just only
type of an API a Connector can expose, JMS is another, and so on.

At the system level, the JDBC driver contracts and the Connector contracts are
very similar. That is the reason why some vendors choose to implement JDBC
driver as a Connector and expose JDBC as an API to the application.

Really from the application perspective, it does not matter, whether the JDBC
API is exposed via a JDBC driver or a Connector. thanks.
