Extension Installer in infinite loop

Question

Hi,
I'm trying to use an Extension Installer to install some extra files for my application. I've searched the forum for problems with the Extension Installer and I've seen a few posts, even the same problem I'm having. But none of the suggestions have helped.
When I run the Extension Installer locally on my own machine it works just fine. However when I move the code to access over the internet the extension installer gets stuck in an infinite loop and my application will never start. And yes, my installer ends with eis.installSucceeded(false).
Based on other messages in the forum, these are some of the things that I've tried, to no avail:
1. Add System.exit(0) as the very last statement in my installer.
2. I don't specify a port in my codebase in either the application jnlp or the extension jnlp.
3. The webserver is running on the default port (80).
4. Tried adding "javaws.cfg.forceUpdate=false" to my javaws.cfg file.
I'm using JWS 1.0.1_02. My web server is IBM HTTP Server. The machine that I'm trying to install to is running W2K.
Anyone have any suggestions?
Thanks,
Beth

Answer 1

The funny thing is that with you it seems to happen
during
one JWS launch session.
So I wonder why JWS will run k instances of your
Extension
installer.
You don't have an <extension> tag in the jnlp file of
your extension
installer, creating an infinite recursion?
Yes, I wonder why I get multiple instances of the Extension Installer. And also that it works fine if everything is running on my local computer. If I just change the codebase and run everything over the internet is when I get it an infinite loop. Any ideas would be greatly appreciated.
If it will help, here are my .jnlp files:
