JNLP - Launch File Error

[Subhash]

Below is the jnlp file and the error I get on launching it. I am not
sure what the problem is. All files (.jnlp, .jar, etc) are in the same
folder and the jar file works perfectly fine. Using Apache, Tomcat and
XP Pro.

Please help. Thanks.

Looking at the message there is an element in the JNLP file missing .... I
cannot recall which are required/optional ... perhaps find the spec to find
out.

I would add some missing elements to at least get it working. The example
below (which launches from a file server) works for me. Maybe it is of some
help.
