Summary

Today's lesson detailed the final J2EE technology supported by WebLogic Server. The day began with the concepts of JCA and what JCA aims to achieve in the enterprise application solution space, that is, solving the "m x n" problem. Then you learned the main constituents of JCA: RA, CCI, and the three system contracts (connection management, transaction management, and security contracts). You learned how the CCI provides a consistent way for enterprise applications, EAI frameworks, and EAI tool vendors to access EIS systems. In the system contracts section, you learned the participants in each contract and the responsibilities of each participant.

Finally, you learned about the support provided by WebLogic Server for JCA and how to configure and deploy an RA in WebLogic Server.

This completes your lessons on the different technologies supported by WebLogic Server. You are now ready to develop and deploy full-fledged enterprise applications using WebLogic Server!
