[rules-users] Drools Execution Server and Guvnor

[Premkumar Stephen]

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:

1) Create a xml or json in the prescribed format (format is documented)
2) Invoke the drools server URL and pass the data.
3) The rules engine ( if deployed from guvnor, will be running at the port
-- check this from guvnor) - will provide you an answer, which you need to
parse back ( from xml or json)

Currently, only stateless calls can be made. Mauricio is working on a
complete rewrite that will allow stateful calls to be made as well.

Regards,
Prem
