2 Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0

The weblogic.xml file contains WebLogic-specific attributes for a Web application. You define the following attributes in this file: HTTP session parameters, HTTP cookie parameters, JSP parameters, resource references, security role assignments, character set mappings, and container attributes.

The deployment descriptor web.xml file is defined by the servlet 2.3 specification from Sun Microsystems. The web.xml file defines each servlet and JSP page and enumerates enterprise beans referenced in the Web application. This deployment descriptor can be used to deploy a Web Application on any J2EE-compliant application server.

Convert your existing weblogic.properties file to the appropriate XML file by following these steps:

1.Start the WebLogic Server 7.0 examples server. For information on starting the WebLogic Server 7.0 examples server, see Starting the Examples, Pet Store, and Workshop Examples Servers in Performing Post-Installation Tasks.

You will be prompted for a user name and password.

2.At the home page for the WebLogic Administration Console (for example:

http://localhost:7001/console/index.jsp) click on the “Convert weblogic.properties” link under the heading Helpful Tools.

3.Use the Console’s links to navigate the server's file system and find the root directory of your previous version of WebLogic Server (for example: C:\weblogic). When you have found the correct directory, click on the icon next to it to select it.

4.If you have additional per server weblogic.properties files or clustering weblogic.properties files in other directories, select them using the provided windows. If you have chosen the correct root directory of your previous version of WebLogic Server, your global weblogic.properties file will be converted regardless of any additional properties files that you select.

5.Enter a name for your new domain in the provided window in the Console. Click Convert.

When you convert your properties file, the web.xml and weblogic.xml files for the default web application are created for you and placed inside a

domain\applications\DefaultWebApp_myserver\WEB-INF directory. The process of converting your weblogic.properties file also creates the config.xml file located in domain. This file contains configuration information specific to your domain.
