Hello Alessandro,
Thank you very much for your quick reply, now it is bit more clear to me
and I will start implementing Puppi today.
One more quick question :-) I need to deploy two 'war' files to the same
server, which means same 'deploy_root' but two 'war' files and I don't
think I can use two 'source' two times.
Any suggestions will be much appreciated.
Thanks & Regards,
Krishna Murthy
