Re: [rules-users] DSL to DRL File Conversion - Is it possible ?
no in 3.0 version unfortunately. You can tell the parser to print out the DRL - but it will just write it out the System.out (only for debuggin). Look in RuleParser for that option. In trunk - which will be the new version - there is a seperate step which outputs DRL - but I don't think that made it into the M1 release - should be in M2 though.

RE: [rules-users] Web service deployment
Yes, my thoughts exactly -- the web service is packaged as an .aar which is nothing more than a jar file. The workaround that i have seen mentioned is to place the data object (Fact) inside a jar and place that into axis2\WEB-INF\lib. That only causes more headaches since everything is generated as xml beans and there is some collision problem. I was wondering if it's possible to get the classes needed by Drools onto the classpath another way at web service runtime? This is all very strange since the rules do correctly see the very same objects when i test them inside eclipse (sans a deployed web service). I suppose JBoss Rules does not really work inside any J2EE container, I thought it should be a simple matter with Tomcat. aj Alan R Jones Boeing SIS Mission Systems Denver Engineering Center (BDEC) 303.307.3415 From: Michael Neale [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 06, 2007 6:39 PM To: Rules Users List Subject: Re: [rules-users] Web service deployment sounds like the classes that are visible to axis are not visible to rules - depends how you are packaging up your application - war or ear?

Re: [rules-users] column binding vs field binding - any performance implications?
Vlad, No noticeable difference in binding fields or columns, but there are really negative perf impacts in using eval(). I'm writing a blog about it. Please try to avoid. I know bellow is just a sample, but it would be so much better if written: Record( field == xxx ) []s Edson Olenin, Vladimir (MOH) wrote: Hi, I wonder if there are any performance implications of choosing column binding vs field binding (I’ll be using bound variable in eval). Eg, in such case: Record($field : field) eval ( $field.equals(“xxx”) ) vs $r: Record() eval ( $r.field.equals(“xxx”) ) Does it start to make difference only when some significant number of variable get bound?

[rules-users] 'from accumulate' doesn't work on multiple columns?..
This is as a follow up for the previous question It looks like I made a
wrong assumption that 'accumulate' can work on multiple columns:
Integer ( intValue 0) from accumulate (
Record ( f1 == $f1, f2 10, $value1 :
value )
Record ( f1 == $f1, f2 = 10, $value2 :
value )
Init ( int sum = 0; ),
Action ( sum += $value1 - $value2 ),
Result ( new Integer (sum) )
)
I'm getting an error ('then' is expected or smth like that at the point
where the second 'Record' is defined) and the only way to remove the error
is to declare one and only one Column constraint... So, it is not possible
then to use multiple columns in 'accumulate'? If not, then it would be even
more interesting to get some idea on how to approach the kind of problem I
mentioned in the previous post.
Thanks,
Vlad

Re: [rules-users] 'from accumulate' doesn't work on multiple columns?..
currently 'accumulate' only works on single column, eventually we hope
to have it working with multipe patterns - but it's not in the near
future road map. Unless a community member wants to work on the feature :)
