Is there any work going on for Drools on .net?
by rahultechie
Hi,
I am currently working on Drools on .net. What I found that the latest
version of drool .net is 3.0 which was developed around 2007. After that
there is work no done on Drool .net.
On above investigation following are my some of questions,
1. Whatever information I got is correct?
2. I want to use drools in my .net project. Latest version of Drools is 5.0
in JAVA, in future can we see Drools 5.0 in .net?
3. Is there any work around for now to use Drools 5.0 in .net?
Any link to above question will be useful.
Thanks.

Problem with sub-process rules inside multiple instances
by HMandic
Does anyone have a working example of a sub-process with rules, inside a
multiple instances node?
I can't get it to work properly.
This sub-process of mine has one script node (that just prints something)
and one rule. Multiple instances node gets a Collection of three elements,
so the sub-process in question should run three times, and it does.
The script node executes three times, as it should, BUT the rule executes
only for the first sub-process, not for the other two!
Just to clarify things - there's no condition in that rule, just a
System.out.print in RHS.

Smart Templates
by ChrisMu
Hi,
I'm trying to get a template (.drt) to generate 2 rules (.drl) from 2
datasets but by doing a little bit more work than direct substitution.
Data (service,value):
DC, AAA
DC, XYZ
Idea for the template - if value is of type1 then create Type object with
'Type1' as name. If value is of type2, use 'Type2' as name:
rule "DC_(a){row.rowNumber}"
when
Service(name == "DC")
then
Type.setName(eval(Service.getType(@{value})))
Type.setAtt(0,@{value})
end template
eval(Service.getType(@{arg0})) should take 'AAA' or 'XYZ' etc as arg and
return a string Type1/Type2 etc.
This would then generate 2 rules that look like:
rule "DC_0"
when
Service(name == "DC", value == "AAA")
then
RiskType.setName("Type1")
RiskType.setAtt(0,"AAA")
rule "DC_1"
when
Service(name == "DC", value == "XYZ")
then
RiskType.setName("Type2")
RiskType.setAtt(0,"XYZ")
...is this possible at all? I'm trying to avoid the eval step being done in
the actual rule (.drl) .
Thanks
Chris

TimerService vs TimeMachine and date-effective
by drdaveg
A common issue that I am looking into is setting the execution date to test
future or legacy rules (i.e., with dates that are not the system date.) A
number of users have posted about TimeMachine, TimeServices and the perils
of setting the system date - but a JIRA lists TimeMachine as being remove
and TimeServices doesn't look like it has a setter for the execution time.
What is the API for simulating the date to be compared against effective and
expiration dates of rules that can be used by stateful sessions?

how to do things like "distinct"?
by Simon Chen
Hi all,
I have the following problem.
Let's say, I have a class Number3(), with three fields a, b, and c.
I have the following rule:
rule "test3"
when
Number3($a: a, $b: b)
$minvalue: Number()
from accumulate(Number3(a == $a, b == $b, $c: c), min($c))
then
System.out.println($a + " " + $b + " " + $minvalue);
end
Say, I have four objects (1,2,3), (1,2,4), (1,3,4), (1,3,5).
The result shows four lines:
1 3 4.0
1 3 4.0
1 2 3.0
1 2 3.0
But I want the output to be:
1 3 4.0
1 2 3.0
meaning that for each unique pair of a and b, I want the rule to fire only once.
Is this doable?
Thanks.

Create rules programatically
by David Godfrey
Hi,
Can someone point me in the direction of documentation or code examples for
the following? I want to programatically create rules for execution, e.g.
within my application I will hold criteria which users will define, at
runtime I would like to build a component to extract these values (from my
app database) and build rules based on those values. Everything I've seen so
far seems to talk about using DRL files, ideally I want to programatically
create the entire rule in Java, and then call Drools to execute my rule set.
Thanks,

Java 7 Support
by Sebastian
Hello,
I tried to use Drools with the OpenJDK 7, but I could not get it to work.
After some debugging I found out, that the map nativeVersions in
EclipseJavaCompilerSettings is missing version 1.7 which is actually defined
as a public static variable.
Can you tell me when you plan on adding JDK7 support?
kind regards,
Sebastian

Re: [rules-users] Reuse of rule
by Küng Sabrina
Thanks for your input. I am looking forward to the plugin.
How can I use a rule in the if-part (or as precondition) of another rule? Is that possible without using a ruleflow?

Hello
How can I write a rule, that can be used in several other packages resp. rulesets without copying the code?
