Hi all!
....ok, what I have found was a similar situation for OS X, how to thread
to run a patched java_swt instead of the java launcher (snip block
below).
Before I start and try to type a wrapper class, I would like to know
what potential problems might occur. Therefore some questions and I
hope, someone could point me to get a workaround.
If a wrapper class is to defined which has to launch the SWT program
about a system call, all vm args, program args and the classpathes needs
to pass through.
To understand the launching order, first javws is launched and calls the
regular java on the system and provide the environment for that?
What is about security, if the wrapper itself and the SWT program in
order take use of system resources? Has the regular java launcher
problems to read the signed jars?
Many thanks for some hints!
Cheers,
Andreas N.

The ugly hack I ended up doing was to make a jar which contained a .zip
of the self-contained application bundle and a small .class to unzip and
run it. Oooogly, but it does run functionally when a Mac user clicks the
web start icon. You do end up with double dock icons and generally
startup feels non-native.
If you don't need WebStart specifically, in general I'd recommend
packaging a Mac version as an application bundle in a .dmg disk image,
the same way most downloadable Mac software is packaged. Unfortunately
you can only build a .dmg on Mac OS X, but a .zip file will often be
good enough if you need to do automated builds from another OS.
When making your .zip (or extracting one from Java code) be sure to set
the executable bit on java_swt (this can be done in Ant by fiddling with
the zipfile task).

Hi all!
I have posted some of my questions in a HP Dev Resource Central forum
and here are the answers from Eniac Zhang
http://devresource.hp.com/forums/thread.jspa?threadID=3721
One remaining and most important question I have:
What are the reasons for the unsupported Motif?
(The SWT FAQ only say: not supported since 2.1)
This means on Solaris and HP-UX no SWT about JWS can launched?!
Thank you for answers,
ANdreas

Andreas,
I think the FAQ entry is slightly misleading in two ways:
1. "As of 2.1" is not meant to imply that this worked previous to 2.1 and
then stopped working. I believe that this entry was added to the FAQ in the
2.1 timeframe, with the hope that it would be resolved in a future version.
2. The problem as I remember it was caused by SWT and AWT (AWT is used by
the JWS mechanism) attempting to access the same motif libraries on linux
simultaneously, and there being a resulting synchronization problem. I'm
not sure if this was ever actually tried on the other motif platforms
though, so if the ones you care about are hpux and solaris then it is worth
giving them a quick try.
