I have tried deploying my application using Java WEB start, but I seem to be getting a lot of security rejections as I test the system. I have digitally signed all of my JAR files as specified in the Java Web Start online literature. Interestingly, I get the exception even if I specify a non-existant JAR file, which confuses me further.
Worse still, it started actually working on a one host after many attempts, but failed when I moved to another nework host.
Specifically, the exception that I receive looks like this:
===========================================
JNLPException[category: Security Error : Exception: null : LaunchDesc: null ]

The JNLP file looks something like this ...
===========================================

I am NOT using Tomcat, but rather a container by a private vendor. Hopefully that is not the problem.
Can anyone help?
