Sorry, it is Mark not Mike :) ________________________________________ From: Santoshi, Vishal Sent: Monday, May 19, 2008 10:32 AM To: 'Rules Dev List' Subject: RE: [rules-dev] SMF drools 4.x Thank u for replying. Mike I had created using drools 2.x drl that looked like the one below. As is evident the ConditionFactory and ConsequenceFactory concept in drools2.x allowed me to parse the conditions tag ( a sunsequent conditon tags ) as I had a good control on parsing the drl file. As also is evident that my condition was an expression , whose lexing , parsing and execution could be controlled by my code. The execution was of course based on a session object that was asserted in the working memory. It also allowed me to identify my Consequences with enhancements. The result of the parsing was a customized Condition object or a Consequnce Object , whose execution ( conditional when as well a than ) was controlled through my code . <rule-set name="qbank" xmlns="http://drools.org/rules" xmlns:g="g" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:schemaLocation="http://drools.org/rules rules.xsd http://doctype.gallup.com/schema/g grules.xsd"> <rule name="reset_next_page_to_current_page" salience="998"> <g:conditions> <g:condition>isBackButtoned() eq ‘true’</g:condition> </g:conditions> <g:actions> <g:assign src="jndi://rules.setNextPageToCurrentPage"> </g:assign> </g:actions> </rule> , , , </rule-set> My question is , whether I would be able to use templating via DSL to achieve the same level of granular control, where the “when” and the “than” can be controlled by my code. I am open to restructuring the code ( ditching it and rewriting it ) provided I can get the same granular control over execution , both during parsing (RuleSet creation) and execution ( Tuple based invoke() and isAllowed() ) . Is that even possible?

Than had to take a sabbatical from that project. As of today, I have been asked to resurrect that project and not a whole lot of drools 2.x has made it to 4.x and of course would like to remain current. You should look at the sentence templating via the DSL stuff. My implementation had an expression engine ( SableCC ) that I had fused in with a customized Semantic Module. I can get more information out for u , if there is a way to resuse some code. Any pointers as to how to go about doing this will be highly appreciated. http://blog.athico.com/2007/12/drools-extensible-process-definition.html seems to be an attempt to explain how the port can take place, but does not seem to have a lot of concreteness around it.
