Good day, I am working on a Web Start page for TightVNC.  The concept is that there is a web page with a list of servers that can be connected to; when the user clicks the hyperlink the JNLP XML is executed.  That I understand how to build.

The problem is that my JNLP file does not not launch the Java Viewer and being a newbie, I not sure what I am missing.

Any help will be appreciated!

Can you elaborate on what kind of problem are you experiencing when you try to launch it?

Sorry I didn't include that up front; I am seeing one of two problems. (1) either the App hangs or (2) i am getting an exception (see screen shot) Exception screen

Maybe you could see anything useful on two other tabs - LaunchFile and Console ?
