Error Installing Additional PIA to the existing Domian

Hi all,              I tried adding a additional site to the existing Domain.(People Tools (8.49.21), Weblogic 9.2), I get " invalid HTTP port " and it starts again asking for Appservername and JSL Port.

First i tried to invoke the installer using this method, It error out as " Exception in thread "main" java.lang.NoClassDefFoundError: run"
Here are the steps

When i try to start the PIA installer using java installer (
$ export DISPLAY=localhost:0.0
$ <JAVA_HOME>/bin/java -cp setup.jar run -console   [where <JAVA_HOME> is the directory where the JRE software is installed. The default is <PS_HOME>/jre.]
I get the below error.
