[izpack-users] log file of Process panel

[Klaus Bartz]

Hi Macke,
you are right in the estimation that logging into a logfile is not
implemented for executed java classes. If you look into ProcessPanelWorker
you will see that there are the different classes ExecutableFile and
ExecutableClass. The first uses redirection for stdout and stderr
which will be write into the panel and may be into a logfile.
ExecutableClass has no OutputMonitor therefore it cannot write into
a logfile. It will be difficult todo it because in opposite to
ExecutableFile ExecutableClass will be performed in process; it has
the same stdout and stderr as the installation self.

Cheers

Klaus
