Going to the test site above gives the following:
$ firefox

Trying with the libxcb/FINAL fix does not change this. jdk6-bin does  
not seem to install sun/plugin/navig/motif/Plugin (nor anything under  
sun/ except some examples and demos).

Does anyone have Java web apps working with our jdk6-bin spell or do  
we need to go back to dkowis' way/fix the current install? Installing  
jre6-bin works just fine, so my guess is it's the way I updated  
jdk6-bin to install (:p David), though I'm pretty sure it used to  
work, perhaps I never tested web apps and no one noticed (except me)  
until now. ;)
