This is because your "campus" object is really a CPS Proxy,
referencing a really campus object existing in the portal_repository
(named the "Content").   So, the proxy object doesn't have the
getHallTitle method, but the content object have.

A __getitem__ method exists in the proxies to do some magic, so your
call http://www.test.de/srp/campus/getHallTitle?hall=xxx works.   To
do the same in a script, you can use either:

context.portal_url.getPortalObject().campus['getHallTitle']("xxx")

or

content = context.portal_url.getPortalObject().campus.getContent()
content.getHallTitle("xxx")

That's no difference between them, but the second option is a cheaper
operation if you need to call more methods or attributes.
