No jre version found in launch file

Question

I'm using jdk1.5.0_03 (with all other versions of java removed from my system) and trying to run our web start app that specifies a version of 1.4.2*. After clicking the link to the jnlp file, web start contacts sun to retrieve 1.4.2*, then gives the dialog: "unable to launch FlowJo" (our app). On the details tab, it reports: "No JRE version found in launch file for this system".
When I launch the web start manager, under the user applications tab, I see 3 applications: our app, our installer, and Sun's j2re1.4.2_07 installer. It seems like Sun's installer is being downloaded but never executed.
Am I doing something wrong in my jnlp files? Both our app jnlp and our installer jnlp specify a j2se version of 1.4.2*. Below are the files and exception as reported from the web start dialog. I'm trying to set our app up for internal testing with web start, so I'm using a local ip. Our application uses a custom installer which has its own jnlp file (shown below in "launch file").
Any help is much appreciated,
Peter

Answer 1

The use of an earlier jre in the resource tag does no
good:
<resources>
<j2se version="1.4.1" />
Still gives the same error;

Can someone please help?
