Can Oracle 10g Express do SOAP calls?

I may have to generate some sample code for accessing a web service I publish using Oracle, and I don't want to get too far in if I can't do it from the free version. (I.E. if it costs money, I want to budget first, learn later...)

So, are you an Oracle guru? Can 10g Express do direct calls to a SOAP based web services (that is without relying on some other middle layer like PHP, Java, or .NET - unless of course that is the "official" way to support calls out of Oracle...)

Thanks!
