This document describes how to build and run the suite of sample applications, which show how Enterprise JavaBeans and CORBA objects can coexist in the same BEA WebLogic EnterpriseTM application. This document is intended for programmers who are interested in creating secure, scalable, transaction-based server applications. It assumes you are knowledgeable with CORBA, Enterprise JavaBeans, and the C++ and Java programming languages.
