2 Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0

Classloading in WebLogic Server 7.0

Earlier versions of WebLogic Server used the WebLogic classpath property

(weblogic.class.path) to facilitate dynamic classloading. In WebLogic 6.0 and later, the weblogic.class.path is no longer needed. You can now load classes from the Java system classpath.

To include the classes that were formerly specified in weblogic.class.path in the standard Java system classpath, set the CLASSPATH environment variable, or use the -classpathoption on the command line as in the following example:

java -classpath %CLASSPATH%;%MyOldClassspath% weblogic.Server

where %MyOldClasspath% contains only the directories that point to your old applications.

Modifying Startup Scripts

If you used WebLogic Server startup scripts with a previous version of the product, modify them to work with 7.0.

„Modify the startup scripts as described in Setting the Classpath in the Administration Guide. The WebLogic classpath is no longer used; use the Java system classpath as described in the preceding section, “Classloading in WebLogic Server 7.0” on page 2-8.

„WebLogic Server 7.0 is started from the domain directory. Make sure that your startup script starts the server from the domain directory.

„It is no longer necessary to include the license file in the classpath.

„With the new management system, there is a distinction between an Administration Server and Managed Servers. Consequently, scripts that start servers must be rewritten according to how you plan to administer your servers. For the new commands and their required arguments, see Starting and Stopping WebLogic Servers in the Administration Guide.
