[izpack-devel] Running the Installer twice without exit/launch ?

some years ago I have written an installation (with InstallShield 5.5)
which contains the base server (product), the custom server data (project)
and the client to write the common parts only once. During maintenance
I have seen, that there was more work as in separated installations.
Now we have three IzPack installations, one server, one admin client and
one agent (the clients are installed with MSI).
For common used custom panels or custom actions normaly I write a base
which do the most and the derived - type dependend - classes contains only
the differences (sometimes empty classes because the needed different
descriptions are automatically selected via the i18n stuff of IzPanel).
I never rued to use different installations. No problems with
no big installation for a admin client, no selection and dependencies
overhead. One installation for one product is better, I mean. For me the
problem begin at our admin clients because there are more than one, but
no separated products else features (in MSI syntax, in other words
OK, that's my experience with a all-in-one device.
In the moment I have not a good feeling about changing the place of
writing uninstall data. And you have already the problem with one
uninstaller.jar; means you cannot uninstall one of your products.
It will be more or less a hack. If you use separated installation most you
need one with less panels and only rare two or three (also less)
which all can be handled (e.g. uninstalled) separatly.
Long time I am missing maintenance with IzPack. At this point MSI is better
than IzPack - nothing is perfect...
I think with this a behavior you need will be easy to implement.
But this implies some fundamental design changes. This will be needed much
Until now I have nothad this time and no working group was found to share
