Axis Client: HTTP-Basic Auth and invalid certificates

[Alexander Czernay]

I finally got my first simple client from WSDL2Java compiled. Now I run 
into the problem, that I have to use HTTPS with an untrusted certificate 
 (javax.net.ssl.SSLHandshakeException: 
sun.security.validator.ValidatorException: No trusted certificate found) 
and that I have to authenticate to the service via HTTP basic auth.

How do I have to set things up?

Thanks for your help,
Alexander
