You can login to the REST api using standard http connection techniques. For 
instance basic auth you can login doing the following:

http://<user>%40<domain>:<password>@<engine_host>/ovirt-engine/api

Will list the available REST api.

But I am still not clear on what you are trying to do. Are you trying to write 
your own external servlet, that calls the REST api to do things for you? Or 
are you trying to write a servlet that lives inside the context of the engine 
and implements a new action?

Also please reply all, so we can keep the discussion on the mailing list so 
other people can find it in the future.
