1 Upgrading WebLogic Server 6.x to Version 7.0

MBean API Change

Previous versions of this document and various other sample documents erroneously described using

weblogic.management.Admin.getInstance().getAdminMBeanHome() as a way to look up the MBeanHome interface on the Administration Server.

However, the weblogic.management.Admin class is not public. Instead of using this non-public class, use JNDI to retrieve MBeanHome. See Determining the Active Domain and Servers in Programming WebLogic Server JMX Services.

Security

Guest and <Anonymous> Users

In WebLogic Server 6.x, any unauthenticated user (anonymous user) was identified as a user called guest. WebLogic Server allowed the guest user access to WebLogic resources. However, this functionality presented a potential security risk so the functionality was modified.

In this version of WebLogic Server, the guest user is no longer supplied by default. WebLogic Server now distinguishes between the guest user and an anonymous user, by assigning an anonymous user the name <anonymous>.

If you want to use the guest user as you did in WebLogic Server 6.x, do one of the following:

„Use Compatibility security. (For more information, see “Using Compatibility Security” in Managing WebLogic Security.)

„Define the guest user as a user in the WebLogic Authentication provider. (The WebLogic Authentication provider is already configured in the default security realm.) You do this by setting the following argument when starting a WebLogic Server instance:

-Dweblogic.security.anonymousUserName=guest

Caution: This argument was added to assist existing WebLogic Server customers to upgrade their security functionality. You should take great caution when using the guest user in a production environment. For more information
