Applet doesn't show after plugin update & using JNLP, no errors

Question

We have an applet that worked after the plugin update, then I wrote the JNLP file and can't get it working, it seems to be loading but doesn't show anything. I have tried and searched for possible errors but doesn't seem to be any obvious error for me. Also JaNeLA doesn't give any errors. When I try to load the applet I can see how open two java consoles (maybe this is an error?), in the first console the last output is:
network: Created version ID: 1.0+
network: Created version ID: 6.0.18
basic: Progress indicator deleted: nullAnd in the second:
basic: Subprogram loaded.
basic: Applet resized and added to parent container
basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt 309262 us, pluginInit dt 2161125 us, TotalTime: 2470387 us
basic: Loading Java Miniapplication
basic: Loading Java MiniapplicationThe jnlp file I wrote is this:

</applet>I know there are many extra parameters in the old version, I have deleted them for debugging because there was the same result with them. What really bothers me is that I don't get any error and the java process is running while tries to load the applet. Anyone had a similar experience and can give a clue?

Hi,
since JRE 6u21 the JNLPAppletLauncher doesn't work anymore.
The Java 3D's jars and native libraries hosted by Oracle.Sun can be accessed by including the extension http://download.java.net/media/java3d/webstart/release/java3d-latest.jnlp. More details can be found here : Java 3D Web Start Release https://j3d-webstart.dev.java.net/release/index.html
See also the example 'H'weight & L'weight in Harmony' http://www.interactivemesh.org/testspace/appletpropelleruniverse1200x800_J3D.html and search in the Java 3D forum http://www.java.net/forums/javadesktop/java-desktop-technologies/java-3d
This is an attempt to adapt your JNLP file :
<?xml version="1.0" encoding="utf-8"?>
