I just committed your patch, with a few adjustments (some parts of the patch didn't seem to have come through correctly).
I already build and tested a demo installer and that looks great!
Thanks for a great contribution.
There are a few issues we need to address but those are minor, e.g. db-psml installation from command-line, using the ant build after installation doesn't seem to work yet.
In addition, we would also like to see support for using Tomcat 6 (hint ).
NB: To be able to actually build an installer does require to checkout and build pluto, jetspeed and portals applications all locally first.
