[PJUG Javamail] Java Web Start on my Mac

[Ted Kubaska]

I'm having trouble getting Java Web Start working on my Mac.  (Jon,  
you've been running Web Start on your Mac forever!) Java itself works  
fine. Eclipse with Java works fine. Here' my version.

newtricks:~ ted$ java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06-153)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_07-b06-57, mixed mode)

I think my issues are very simple, but I'm really kind of stuck.

I'm just trying to run a demo. A hello world demo ... just to see how  
it works.
I went to  http://www.treelight.com/software/JavaWebStart/index.html
and clicked HelloWorld.

I get a screen that says

HelloWorld Demo
Click here to launch the application.
(It will be downloaded if it isn't already installed.)

I click on "Click here." I get a screen that asks if I want to open  
with Java Web Start. I click on OK. I then get a screen that says  
"Java Web Start Starting ..." and then I get a screen after a few  
seconds that says "Unable to launch application" I click on Details,  
then Exception and see
