Trying to call a Java3D application from .jnlp file

Question

Hi everybody,
I'm trying to execute a java3D simple program making use of a *.jnlp* file, but isn't working...
Can anybody help? Thanks in advance.
This is what I have:
simple.jnlp
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+"
codebase="file:///the_path/jnlp/">
<information>
  <title>Hello JNLP</title>
  <homepage href="http://whatever.com" />
  <vendor>My self </vendor>
  <offline/>
</information>
<resources>
  <j2se version="1.2+" />
  <jar href="bin/HelloJava3Da.jar" />
  <jar href="bin/j3dcore.jar" />
  <jar href="bin/j3dutils.jar" />
  <jar href="bin/vecmath.jar" />
</resources>
<application-desc main-class="HelloJava3Da" />
</jnlp>First, I had to generate the HelloJava3Da.jar, which contains HelloJava3Da.class (my program compiled and working when using java command).
Generation of HelloJava3Da.jar :
$ jar cf HelloJava3Da.jar HelloJava3Da.class
$ jarsigner -keystore myKeys HelloJava3Da.jar jdcFinally, when I try to run simple.jnlp, making use of Firefox:
firefox simple.jnlpThe result is:

I have a collection of Java3d applets launched with Java3d:
