6.5 Summary

This chapter has described designs and guidelines for integrating enterprise information systems into enterprise applications. These guidelines enable an application component provider to develop an enterprise application based on its overall functional and system requirements for EIS integration. The chapter focuses on accessing EIS resources from a component, using tools to simplify and reduce application development effort involved in accessing EISes, obtaining and managing connections to EISes, and supporting the security requirements of an application.

The current version of the J2EE platform includes the Connector architecture version 1.0, which provides full support for integrating all types of enterprise information systems, including database and legacy systems, with the J2EE platform. The JDBC API is also available for accessing relational databases. Asynchronous messaging is available through the JMS API.
