J2EE Connector Technology

by Dale Green and Beth Stearns

The other chapters in this book are intended for business application developers, but this chapter is for advanced users such as system integrators and tools developers. The examples in this chapter demonstrate the J2EE Connector Technology by accessing relational databases. However, this technology is not a substitute for the JDBC API. Business application developers should continue to use the JDBC API to access relational databases.

The J2EE Connector Technology enables J2EE components such as enterprise beans to interact with Enterprise Information Systems (EIS). EIS software includes various types of systems: Enterprise Resource Planning (ERP), mainframe transaction processing, non-relational database, among others. The J2EE Connector Technology simplifies the integration of diverse EIS systems. Each EIS requires just one implementation of the J2EE Connector Technology. Because an implementation adheres to the J2EE Connector Specification, it is portable across all compliant J2EE servers.
