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 weblogic.properties 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:
http://WebLogicURL:port
(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
weblogic.properties 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:
http://WebLogicURL:port/AdminMain
Options available from the WebLogic Admin home page
The home page displays a summary of WebLogic Server status. You can get
