Setting up WebLogic CORBA access

Steps: Before you begin; Edit the weblogic.properties file; Start the WebLogic Server; More resources

Before you begin

WebLogic supports access to WebLogic Events and WebLogic Remote services from a Visigenic CORBA client. This document includes instructions for setting up this service.

With release 3.1, the Visi-to-WebLogic proxy is compatible with VBJ 2.5 or 3.0. Most often, clients will be using Visibroker from a Netscape Communicator 4 browser, which (through Netscape Communicator 4.04) supports only 2.5, although a later version is now available from Visigenic. Consequently, WebLogic only supports IIOP tunneling with Visibroker version 2.5 to remain compatible with Netscape browsers.

Please refer to Running WebLogic with the Java 2 SDK for additional information about CORBA support. Also see, Accessing WebLogic Server object from a CORBA client through delegation for additional information on how to use CORBA with WebLogic Server.

In this document, we assume that you have followed the instructions for installing WebLogic.

Edit the weblogic.properties file

The T3Client can access the WebLogic Server with several access methods, including HTTP, and now CORBA. T3Clients using CORBA currently have access to WebLogic Events and WebLogic Remote services, two of the many services available in WebLogic. For the CORBA IDL description of these services, please see the t3client.idl in the distribution directory weblogic/src/idl/.

Starting up the WebLogic Server is a simple process; for more detailed information, read about starting and running the WebLogic Server in the WebLogic Administrators Guide. Before you start the WebLogic Server the first time, you will need to edit your weblogic.properties file and set a few required properties. The weblogic.properties is located in the weblogic/ directory in the distribution.

Distribution

The properties that you must set are located at the top of the properties file and include an administrator's password for the WebLogic Server and the port at which the WebLogic Server should listen for login requests.

In addition to general properties for running the WebLogic Server, you should also uncomment (if you are using the properties file from release 2.5 or later) or add an additional property that registers a startup class. To make this property active, first find the section called "# SYSTEM STARTUP FILES", and then uncomment the following lines:

weblogic.system.startupClass.dovisi=weblogic.corba.visi.t3server.Startup
weblogic.system.startupArgs.dovisi=\
       clientName=T3Client Manager,\
       connName=T3Connection Manager

When the WebLogic Server starts, this class creates and starts a VisiServerThread in the WebLogic Server that runs as a CORBA server.

There is detailed information about setting properties in the WebLogic Server Administrator Guide, Setting WebLogic properties.

Start the WebLogic Server

Start the WebLogic Server according to the instructions in Setting up and starting the WebLogic Server

See the WebLogic Administrators Guide for detailed instructions on administering a WebLogic Server. The WebLogic Server has extensive properties to give you a fine degree of control its operation.

The IDL for T3Client CORBA access to WebLogic Events and Remote services in WebLogic is located in the distribution in weblogic/src/idl/t3client.idl. The IDL mimics the Java API for WebLogic Events and WebLogic Remote services.
