[rules-users] Can Guvnor's repository functionality be exposed as a web service? [was: Drools API]

[Patricia Bogoevici]

thanks a lot for your answers. 

indeed, as Michael figured out, I need to be able to save rules, as well as query rules using the repository service, and retrieving all the details about rules from the repository.
I'll take a look at Drools server just in case it can be extended. 

thx,
Patricia

Yes, thank-you.

This example appears to expose RuleAgent operations as a web-service.

Unfortunately it does not provide the granularity to individual rules, categories, versioning etc that I thought the original poster may have wanted.


It is none-the-less an interesting article.

Seems you can use drools server to do it.

I know of the following (but not used) which might help point you in the right direction.

There is org.drools.guvnor.server.GuvnorAPIServlet (drools-guvnor) which provides a narrow API for dealing with repository artifacts. There is also a narrow REST-ful API in org.drools.repository.remoteapi.RestAPI (drools-repository, which is the backend to which you refer). Class org.drools.guvnor.server.RepositoryServiceServlet is the "meat" of Guvnors actions but it is tightly coupled to GWT and hence less useful as a generic external service. Unfortunately I doubt any will be entirely useful for your use-case without extensive enhancement. If you do end up creating a generic web-service exposing RepositoryService please consider giving back to the community.

This is the scenario that I am looking for:

I am using Drools Guvnor as the central rule repository. I also have

an external application, that has a custom rule editor in place, and

users can create rules. This custom rule editor will take care of

Conditional Elements and Consequence actions. I would like to be able

to save the rule back in Guvnor, as that is the rule repository.



In the docs, there says that Guvnor has 2 parts: front-end and

backend. The backend includes the repository access as well. My

question is if the Guvnor backend exposes the repository functionality

as web service, or if it can be easily exposed.



Thanks,

Patricia
