[rules-users] exposing drools as a webservice

Hi, I am trying to setup a basic webservice that exposes a rule running on drools. In this regard I came across this blogpost by Mark Proctor a while ago. http://blog.athico.com/2007/05/working-with-jboss-rules-and-web.html Incase someone has a working sample of such an example, it would be great if you could share it with me. IF this is not possible, can you point me to a resource where I could access such a sample. I am new to the SOA world, so kindly bare with my if this seems to be a straightforward question. Any pointers would be much appreciated. Thanks Prem
