build failed again

Well!! n-th run, build failed again with same message as posted here - http://javagongura.blogspot.com/2009/11/build-failed-on-line-3121.html

After this step. installation aborts.
Checked the App Server installation log, it was a successful installation.
Though its a failed installation, I tried to start the app server services.
I found some *amazing* things in startServer.log -

This line in the above stack trace *Executable: [/opt/XYZWEBSPHEREXYZ/AppServer/java/bin/java] does not appear to be a valid executable. Process could not be created.* amazed me.
Why startServer is trying to look for java in /opt/XYZWEBSPHEREXYZ/AppServer/java/bin/java?

So, I have created folder structure like /opt/XYZWEBSPHEREXYZ/AppServer/java/bin/ and created a softlink to original appserver/java/bin/java.
But, its looking for remaining binaries in the same location.
So, need to create softlink for the entiar installation under /opt/XYZWEBSPHEREXYZ/AppServer/

Lets see...
BTW - Found a technote on this -
http://www-01.ibm.com/support/docview.wss?uid=swg21202564
The technote mentions that, because its a broken installation, you get such an error.
