The Getting Started presents an overview of the BEA WebLogic Enterprise (WLE) product and describes the development process for developing distributed CORBA and Enterprise JavaBeans (EJB) applications using the WLE software. The 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.
Overview of the WLE CORBA Programming Features
How WLE CORBA Client and Server Applications Interact
Step 1: The server application is initialized.
Step 2: The client application is initialized.
Step 3: The client application authenticates itself to the WLE domain.
Step 5: The client application invokes an operation on the CORBA object.
Overview of the WLE EJB Programming Environment
Types of Beans Supported in WLE
Roles of People Who Develop, Build, Deploy, and Administer EJBs
Items You Create for an EJB Application
Tools and Facilities Provided for Building and Deploying EJBs

Step 4: Write the client application.
Step 5: Create an XA resource manager.
Step 6: Create a configuration file.
Step 7: Create the TUXCONFIG file.
Step 8: Compile the server application.
Step 9: Compile the client application.
Step 10: Start the WLE CORBA application.

Overview of the EJB Building and Deploying Process
Steps for Building and Deploying EJBs
Step 1: Obtain the EJB JAR file from the bean provider.
Step 2: Modify the deployment descriptor.
Step 3: Create the WebLogic EJB extensions to the deployment descriptor DTD.
Step 4: Produce the deployable EJB JAR file.
Step 5: Configure the EJB application.
