2F, It looks like your javaws command is the one from the jnlp.sourceforge.net project. My best guess is that it was installed with the openjdk-6-jre package. I was hoping that the banner from -version would verify that.
Using the sun-java6 (on gutsy) 'javaws -version' shows
Java(TM) Web Start 1.6.0_03
Does /usr/lib/jvm/java-6-sun-1.6.0.04/jre/bin/javaws work for you?
