Pradeep,
Please go through the entire documentation to understand how the rules are
persisted.
The default persistence for guvnor is through a Jackrabbit repository, but
it can be configured to use several databases.

Hi Vignesh,
Please read Mauricio's explanation above on when to use.
In addition, this approach frees you up from using Drools from only java
applications. For instance, we invoke the rules engine from Rails code.
Basically, you need to do the following steps:

There is sample code available when you get the source code from the trunk.
Is there a reason you are choosing the execution server, over directly
invoking the rules?

Hello,
We currently use drools-server to execute rules from our ruby environment.
I have been reading about Thrift, originally from Facebook but now in Apache

Has anyone worked on this approach, or thinking about doing so?

Ruben,
Drools Server is a web service which executes rules that can be deployed
from Guvnor.

Hi,
I built the source from trunk and added the drools eclipse plugin.
I was asked to create a new Drools 5 Runtime directory.
I pointed it to a directory that has all the jars, but I still get this

Is there any documentation on how to set up

1) You need to read http://www.jboss.org/drools/lists.html (the list of

Currently, the validate functionality ensures that rules have proper
syntax.
it is possible to extend this functionality so that business use cases might
also be validated? Is there an API/examples to do that.

The order of the DSL entries matter.
You should interchange the first and second lines in the DSL that you have
provided.

How are you executing the rules? Are you using web services via the Drools

if you are able to create your packages, then you do not need the guvnor,
since guvnor merely automates it for you.
create a xxx.properties file in your classes folder ( where xxx is the
package name )
This is documented in the guvnor documentation --> search for drools-server

Mark has provided the elegant way to do it. However, as a newbie, it can be
done simpler without using this API for stateless rules,.

Hello Folks,
I have been looking at options of using ruby objects as fact objects in

One obvious way is using services.
