getting the app server DNS and port at runtime

["Arnett, Matt" <Matt.Arnett@xxxxxxxxxx>]

For a J2EE application running in WebLogic 8.3, does anyone know how to get the app server DNS and port at runtime which is servicing the request?  Calling InetAddress.getLocalHost().getHostName(); and request.getRequestURL(); provide the actual server name and/or URL entered in the web browser.  But this is generally the clustered version of the URL and not the actual app server which ended up processing the request.

 

One thought I had was to add some command line JAVA_OPTIONS to the weblogic startup scripts which would “hard code” the real server DNS and port for each server in the cluster.  And then call System.getProperty(“myprop.appserver.dns”); and System.getProperty(“myprop.appserver.port”);.  This would be good because it would be available at every tier of the application.

 

But this requires additional configuration which I would like to avoid.

Thanks,
-Matt
