Hi - I'm a little confused about the relationship between jca and jta. Does anyone have any information that might be useful.

JCA == Java 2 Enterprise Edition Connector Architecture. A standard API for using Enterprise Information Systems like SAP, Peoplesoft, CICS, etc. It includes a function-oriented call interface and ways to map results to ResultSets (ala JDBC) or objects. JTA == Java Transaction API. JTA is a high level, implementation independent, protocol independent API that allows applications and application servers to access transactions. Where they come together is in the EJB and J2EE spec. The goal is that you can start transactions in an EJB (either an MDB, a Session or an Entity bean) and that if you call a JCA connector that the transaction on the EIS side (for instance a CICS transaction) will be managed by the same Transaction Manager that is managing your EJB transaction. That means a single 2-phase commit transaction could cross a JDBC database, a MOM accessed through JMS, and an EIS accessed through JCA. Kyle
