Getting Started
This document presents an overview of the BEA WebLogic EnterpriseTM (WLE) product and describes the development process for developing distributed CORBA and Enterprise JavaBeans (EJB) applications using the WLE software.
The Getting Started document does not discuss every feature of the WLE product; instead, it gives a general description of building a typical application or bean using the WLE programming environment. To find information about all the WLE features, see the home page of the WebLogic Enterprise online documentation.
This document is intended for programmers who want to familiarize themselves with the WLE programming environment and create either distributed CORBA or Enterprise JavaBeans applications using the WLE product.
