Personally, I use the Spring framework to provide SOAP (and REST) web services to other applications. It's relatively simple to set it up and I'm fond of the contract-first approach which it encourages. With regards integration with Drools, it's easy enough in Spring. You just need to create a Spring bean to act as the interface to your knowledge base. That way, Spring ensures that you have only one knowledge base instance in play, so it is configured and compiled when the application starts. I'd be happy to answer any Spring/Drools integration questions (I don;t tend to use other web frameworks), and I can provide some code examples if Spring is the way you wish to go.

Does this mean that you can not have more than one knowledge base configured? My application basically needs to offer the ability to edit and test a user's own rules and facts (in a way similar to what Guvnor does but much more simplified) and I do not know if that can be done using just one knowledge base and sessions. I was thinking of having a separate knowledge base per user and using a KnowledgeAgent for updating but I have yet to test this approach. -- View this message in context: http://drools.46999.n3.nabble.com/Web-services-and-Drools-tp4021509p40215...
