Using the WebLogic Admin facility

The WebLogic distribution includes a set of Java-Server-style servlets (that is, they follow the java.servlet.* API from JavaSoft) that allow you to view aspects of WebLogic with a browser -- the Admin* classes.

To use the WebLogic Admin facility, you must have a WebLogic Server running to which you have the administrator password access.

Locating the AdminMain servlet

WebLogic is shipped with the AdminMain servlet set as the default servlet (the weblogic.httpd.defaultServlet property in the file). That means you will be served the AdminMain servlet whenever you issue an HTTP request to the WebLogic Server that it can't map to a servable class. Within this default setup, you can just enter the URL of the server to get to the main WebLogic Admin page, after this pattern:
(Port number is only required if the WebLogic Server is not listening on port 80.)

You will be presented with a dialog box to enter username and password. Enter either "system" and the password you set for the user "system" in the properties file, or any other username and password that you have registered for servlet access in the file. The "system" username and admin properties will always give you access to the most privileged commands and services in the WebLogic Server, including HTTP access.

Note that you cannot access the WebLogic Server admin facility if you disable HTTP access.

If you change the defaultServer to another servlet (for example, to the HttpdProxyServlet, so that unservable requests are proxied to another HTTP server), then you can reach the main admin page with this URL:


Options available from the WebLogic Admin home page

The home page displays a summary of WebLogic Server status. You can get general help and navigation instructions by clicking Help in the toolbars running across the top and bottom of the page. With release 2.2, there is detailed help on properties and more general help on other topics.

Other available information in the WebLogic Server admin facility (check the toolbar that runs along the top and bottom of every page):
