bea integration

Hi,
i'm just new with microsoft mappoint, and i'm trying to access services from java client. I've tried the Axis sample application available on microsoft site and it works fine.
however i would like to know if it is possible to adapt this example for use on the bea platform.
if anyone has a really simple application for bea it would help me greatly.
i mainly think the hard task is to implement the the digest authentication required by mappoint on server side.

thanks
