Making my own agenda Filter
by Mehak
Hi I am using this code to make my own agenda filter. In this case if the
type of rule is agenda then agenda filter to focus on that agenda is set
else agenda filter for rule is set.
private static AgendaFilter buildAgendaFilter(RuleConfig rule)
{ final String searchName = rule.getRuleName();
final String type = rule.getRuleType();
AgendaFilter filter = new AgendaFilter() // The control doesnt go inside
this code
{
public boolean accept(Activation activation)
{ if(type == "AGENDA")
{
if((activation.getRule().getAgendaGroup()).equalsIgnoreCase(searchName))
{ System.out.println(searchName);
return true;
}
return false;
}
else
{
if((activation.getRule().getName()).equalsIgnoreCase(searchName))
{
return true;
}
return false;
}
}
};
return filter;
The problem is that the control doesnt go inside the new agenda creation.
Please let me know if something is wrong with the way I have used it.
Thanks

Problem using Package Builder
by Mehak
Hi
I am using Package Builder for making rule base in my web application. The
code is:
public class DroolSetUp implements ResourceLoaderAware{
private static RuleBase ruleBase;
private Resource drlFiles;
public void setResourceLoader(ResourceLoader arg0) {
try {
ruleBase = RuleBaseFactory.newRuleBase();
File file = drlFiles.getFile();
FileInputStream fileStream = new FileInputStream(file);
Reader source = new InputStreamReader(fileStream );
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromXml(source);
System.out.println(builder.toString());
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg );
}
catch(Exception e)
{
}
}
}
But there is a problem that the method returns after the statement
PackageBuilder builder = new PackageBuilder();
Please le me know what the problem can be.
Waiting for an early response
Thanks

Unable to access setter fields of fact in RHS using guided rule editor
by David Godfrey
Using Drools 4-0-4, I am trying to setup a very simple prototype system to
use either of the Guided Rule Editors in Eclipse or BRMS.
I have created a simple bean class to act as my Fact, and can see this when
setting up the LHS, e.g. I can create a condition that a field in my fact
must equal "X".
I then want to set a different field to a new value as the RHS, but in the
"Then" section of the guided rule editor, when I try to choose a value from
the drop down list option "set the values of a field on", I do not see my
fact, hence I can't access it to set the value I want.
I get the same behaviour using both Eclipse and BRMS guided rule editors,
e.g. my Fact bean is accessible in the LHS but not the RHS?
I've read and re-read the user guides and documentation, and tried using the
supplied example Drools projects as the basis of some guided rules, but I
always get the same result.
Any suggestions much appreciated.

RE: Can I use drools to solve my problem?
by Anstis, Michael (M.)
In my opinion it will be much easier if you insert individual Orders and
Products
Here's a hurriedly put together example to help you think in terms of rules
(I have no experience of your problem domain so this might be laughably
wrong):-
Global ArrayList branch1;
rule "Delievery split - Branch 1"
when
$p : Product( $b : branch = "Branch 1" )
$o : Order( products contains $p )
then
OrderDelievery od = new OrderDelievery($o, $p, $b);
insert(od);
end
rule "Consolidate delieveries"
when
$od : OrderDelievery( branch = "Branch 1" )
then
branch1.add($od);
end
Or you could just retrieve the OrderDelievery objects from WM at the end.
Drools can definately achieve what you want. If you can solve the problem
with hard-coded rules you can solve it with Drools.
Good luck,
Mike

Subject: RE: Can I use drools to solve my problem?
alright. I was trying not to boder you.
My companie is developing a billing software for a e-commerce site. So we
have an Order and we have to transform it into deliveries. So each Order has
many products and I have to filter it and define X deliveries(i call it
'delivery split'). There are filters like disponibility(in how many days it
will be ok), brach(in what city is the product), type(if it is a kit,
ticket...),...
I tried many ways and i really think that drools isn't the best tool for my
problem. The point is that mi boos dont want to use the hard code for define
the deliveries. He wats drolls to do everything. So i tried inserting the
the order in the WM, and using 'rom' chained with 'collect' i could iterate
and set a list based in some rules, but how can i create lists based on the
branch. how can i group in Y different lists the Z different products i
have.
I also inserted each product manually and tried to manipulate each one. But
the point is that the rules should be interdependent but i was not able to
do it.
the resume is that i want to take the order and set N deliveries based on
interdependent rules. i would like to do almost everything with drools not
using the hard code.
Sorry for the English, thanj you very much for the help, i'm a little lost.

Setting date during execution of rules.
by Nimesh Muley
Hi,
Is there a way to set the date while executing the rules? The effective dates would be checked against this date instead of today's date. By default the effective dates would be checked with System date. But in some cases we would need to execute the rules in a 'back-dated' mode.
Use case.
Let's say in insurance industry there are commission calculation rules for an agent. On these rules the effective dates are appropriate (as per their needs). Now when an agent is promoted and his/her promotion date is couple of months back then we would want to calculate the commission once again with the date as 2 months back.
The nearest I could see is TimeMachine, as this is being used during execution of rules. Although I could not find a way to set the TimeMachine in release 4.0.4.
Has anyone tried something like this before?
Regards,
- Nimesh

Maven compilation mojo?
by Eric Miles
Is there a Maven Drools compilation mojo, provided either by the Drools
team or some open source project? If not, I have one that I'd be
willing to submit. I think it's pretty slick and would only require a
few tweaks to truly make it useful (hard coded to currently use XStream
serialization).
