Dell iDRAC JViewer and FreeBSD 9.0: not working, help!

[O. Hartmann]

We use a Dell rack system with a JAVA based virtual console facility, 
iDRAC6, which works well when used via Windows 7 or some Linux boxes. On 
FreeBSD 9.0/amd64 (most recent) with JAVA
diablo-jdk-1.6.0.07.02_13 Java Development Kit 1.6.0_07.02
openjdk6-b22_2      Oracle's Java 6 virtual machine release under the GPL v2
installed, I receive the virtual console after referring 'javaws' (Java 
WebStarter) as the appropriate application staring a kind of *.jnl 
application, but I receive an error:

I do not understand much why JAVA, platform independent, is not working 
with FreeBSD as expected. Linux- und Windows are working.

Any help?
