You can probably put an exception into the Java Control Panel Security 
Tab and get it to run.  The problem is that there will be all sorts of 
warnings.  I had a real cert a couple of years ago and did some tests 
but I think that JavaWS is basically dead because of all the security 
issues.  Even with the cert there are a lot of warnings.
