The NoClassDefFoundError is because the EA1 release https
handler support is dependent on Sun JVM internal classes under the
sun.* Java package hierarchy and access to these classes requires a
security permission if you are running with a security manager. The
dependency will be removed before the final 1.0 release.

The https handler finds it's default list of trusted
CA certificates from the jre/lib/security/cacerts file. You can view
or edit this using the keytool utility command from Java 2. Since
you are getting the "untrusted" exception this implies that your server
certificate was not a standard certificate issued by one of the
well-known CA root certificates listed in the cacerts file (VeriSign).

Configuration of the https handler should be a little more
flexible in the next EA release. In the meantime, you may be able to
use keytool to add additional trusted certificates to your cacerts
file.
