The default location for installing Application Server is /opt/SUNWappserver/appserver in the Solaris operating environment and /opt/sun/appserver on Linux systems. If you installed Application Server in a different location, you must edit the file install.properties before you configure Service Registry.
In the ServiceRegistry-base/install directory, open the file install.properties in a text editor.
Find the commented-out definition of the property appserver.root.dir.
Remove the comment character (#) and replace the property definition with the actual location of Application Server.
Save and close the install.properties file.
Continue with the instructions in Configuring Service Registry.
