I have an application which requires JSSE. As deploying JSSE as a simple set of
signed JAR files doesn't seem to work, I have created an installation program
that downloads jnet.jar, jsse.jar and jcert.jar into the lib\ext directory of
the runtime.
I have tested under Windows 95, Windows 98, Windows 2000 and it works fine each
time. Under Windows NT it worked on a workstation but on another, the
installation loops.
The failing machine was set to "Workgroup" instead of Domain.
If it is part of our NT Domain, it works, if it's set to "Workgroup"
the installation loops.

Here are the two JNLPs:

1/ JWS downloads the first three jar files (myapp.jar, mynative.jar and jh.jar)
to the cache.
2/ JWS launches the JSSE installation after displaying the Grant dialog box. It
ends successfully (can see the message and the JSSE JAR files are indeed in the
ext directory).
3/ The console window popping up and goes away immediatly and JWS installation
window comes back. It's resuming the installation of the application, but it
skips the first part as it was already downloaded.
4/ It relaunch the JSSE installation which still ends successfully and back to
step 3 over and over.

The platform is Windows NT Service Pack 6.
JWS uses 1.3.0_03 (but I've tried with 1.3.1 with the same result), my
application uses 1.3.1_01.


As for the installation program, here it is:
