Things can be very straightforward if your web application is GWT based.
You can use GWT RPC to talk to the Guvnor server. See
trunk\drools-guvnor\src\main\java\org\drools\guvnor\server\ServiceImplementation.java
for details. Most functions that are called from Guvnor GUI are
implemented in this class. If this doesnt work for you, you will need to
somehow expose Guvnor server side functions (ServiceImplementation.java)
by yourself, eg, through a Servlet or through a RESTful service
interface.  Unfortunately Guvnor does not have this capability yet,
though there were some talks about implementing such features in the
future. You may want to take a look at Apache CXF [1] or JBOSS RESTEasy
[2] on how to use a JSR-311 implementation to publish Guvnor as Restful
(Atom/Pub) services. Let me know if you have interest to explore this
further, I can provide more information on this.
