2 Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0

WAR Files

A WAR file is a Web Application archive. If you have correctly followed the prescribed directory structure of a Web Application and created the appropriate web.xml and weblogic.xml files, it is strongly recommended that in production environments your applications be bundled together in a Web Application deployed as a WAR file. Once you have bundled your applications into a WAR file, it is important to remove the previously existing directory structure so that WebLogic Server only has one instance of each application.

Use the following command line from the root directory containing your Web Application to create a WAR file, replacing ‘webAppName’ with the specific name you have chosen for your Web Application:

jar cvf webAppName.war *

You now have created a WAR file that contains all the files and configuration information for your Web Application.

Deploying Web Applications

To configure and deploy a web application using the WebLogic Server Administration Console:

1.Start the WebLogic Server Administration Console.

2.Select the Domain in which you will be working.

3.In the left pane of the Console, click Deployments.

4.In the left pane of the Console, click the Applications. A table is displayed in the right pane of the Console showing all the deployed Applications.

5.Select the Configure a new Application option.

6.Locate the application archive, or the directory containing the exploded application. Note that WebLogic Server will deploy all components it finds in and below the specified directory.

7.Click the icon to the left of a directory or file to choose it and proceed to the next step.
