Re: [rules-users] Exposing the rule engine as a web service to be accessed by the client
Sorry I could not be of more help. I have only played with Guvnor with existing default server settings.

Guvnor connection wizard is completed, but the new Guvnor repository connection does not appear in the Guvnor Repository Explorer. I cannot expand the tree to view Guvnor repository contents.I access internet through a proxy. I even tried adding the drools5.0.0 eclipse-all plugin in eclipse 3.4 . Same problem like above. Am I missing some configuration settings,for my tomcat in the drools-guvnor.war. I have not read about guvnor.And the link you sent is also with guvnor. Do you have any reference ,where guvnor is not used ,just simple drl files in the drools execution server ,with how is the xml data sent from the client to the server. Really in a big mess.Deadline too close.Just 2 more days. Please help Regards Tanzu pkpkpkpk wrote: Mark has provided the elegant way to do it.
