Web Start reporting <gapdataclient.jar> missing when it's not

Hi,

I have set up a web server for installing Java applications using WebStart.  However, when I try and launch a particulat application I get the following error in WebStart:


An error occurred while launching/running the application.

Category: Launch File Error

The following required field is missing from the launch file: <jnlp>(<application-desc>|<applet-desc>|<installer-desc>|<component-desc>)



The Stack Trace follows as does the launch File as per WebStart.  As you will see an application-desc element does exist?  Any ideas?


MissingFieldException[ The following required field is missing from the launch file: <jnlp>(<application-desc>|<applet-desc>|<installer-desc>|<component-desc>)]
