Change Scanner does not start
by Antonio Anderson Souza
Dear All,
I have an application that use Guvnor 5.4.0 final as the rules repository
and a DroolsServer 5.4.0 final (with Spring Camel) to provide rule engine
via a Rest Webservices, all of those apps Running in a JBossAS 7.1.
All of the service are working perfectly, except the
resource-change-scanner that is configured in the knowledge-services.xml
[1] as it's described in the documentation.
When Drools-Server are deployed the Change Scanner does not start (I'm
monitoring the change scanner via Wireshark analyzing the communication
between DroolServer and Guvnor), I've created an small JSP file [2] that
invoke the ChangeScanner start method, when i run the JSP the Change
Scanner start to work (i can see the http requests from Drools Server do
Guvnor to see if the knowledge base had changed), but after Change Scanner
started working the rules are not triggered anymore.
So without Change Scanner I've all of the knowledge service running
properly, but the App is unable to detect rules changes, when I explicitly
(via JSP) start the Change Scanner all of the knowledge service stopped
working.
Change Scanner starts automatically?
Does anybody has some idea to help me?

How to start with Drools Fusion as a Java enterprise newbie
by Thomas Söhngen
Hi,
I am currently evaluating Drools for our needs, from the features it
seems to be a perfect fit. I am a Java developer, but unfortunately I
have no background in enterprise application servers and I am currently
stuck trying to setup a testing environment. A short summary of our
current setup and how we want to use Drools:
* We are using Storm <https://github.com/nathanmarz/storm> to
accumulate a large number of messages from around the web
* From these we create streams of message metadata (like sentiment)
for different topics (like stocks)
* We have additional streams like stock-tickers
* We have a knowledge-base of additional facts about companies (like
market cap.) in MySQL
* We want users to be able to define alerts triggered by rules based
on these streams and facts
Storm is perfect for the data pre-processing and aggregation, Drools
would fit in to allow outsiders to define rules and evaluate them on the
streams in realtime. My idea is, to run Drools Fusion as a stand-alone
application on a dedicated server or cluster of servers. Drools Guvnor
would be used as an interface for the rules. The rules would trigger new
events, which would be sent to a subscription channel (like Redis Pub/Sub).
As mentioned above, I have no experience in setting up and running Java
application servers. The Drools documentation seems to be very
elaborate, but assume that you know how to start such a service from
scratch, which I don't. I know Java, but not at an enterprise level, so
all the Beans, wars, etc. are new to me. I setup a JBoss AS, which was a
pretty easy thing to do, but I am clueless about how to really "run"
Drools on it and what to do next.
So what would be the next steps to get a server, where I can send
messages to? Are there any tutorials or guidelines which describe how to
built such a thing from the very beginning? Any help or suggestion would
be very appreciated!
Regards & thanks in advance,
Thomas Söhngen

XOR Rules
by Bojan Janisch
Hello everybody,
is there a way to XOR two rules? So if one condition is passed,
that not a specific other rule fires, even if that condition
also passed.
Thanks in advance.

Still stuck on simple test case
by Michiel Vermandel
Hi,
I'm still (or again) stuck on an easy test case.
A few days ago I first mentioned I had I very easy unit test that easily could be solved on sight but which was not solved optimal by planner.
Geoffrey pointed out that I needed to adjust the value of entityTabuSize in my localSearch acceptor configuration.
I did so (reducing from 7 to 3) and it worked, but now, having fiddled a bit on one of my rules I'm stuck again on the same issue.
I created a custom solver phase to force a specific solution and when adding this phase into my configuration I get a zero-score solution, namely the solution I forced.
So it does not seem to be an issue in my rules.
As suggested before by Geoffrey, I have put the logging level to debug and I get a lot of output like this (see beneath), but I don't really know how this can help me in solving the issue:
(I left out a lot of lines, I hope I left in the important ones)

Dates in an XLS decision table
by tad628
I'm new to Drools and trying to figure out how to build a condition around a
date. Using DRL, it might look something like this:
rule "Simple percentage with incentive date X"
when
$i : LineItem( status == LineItem.PROCESSING, $amount : amount,
$orderDate : orderDate )
then
Date $incentiveDate = new GregorianCalendar(2012, 0, 1).getTime();
Date $incentiveDate2 = new GregorianCalendar(2013, 0, 1).getTime();
if ( $orderDate.before( $incentiveDate ) )
....
else if ( $orderDate.before( $incentiveDate2 ) )
...etc.
I can't figure out how to do this in a spreadsheet, however. For the
condition I have the two lines below the "CONDITION" cell as:
LineItem
orderDate.before( $param )
with the various dates as rows down in the data section.
When I run this, I get an exception of that "unable to resolve method using
strict-mode: java.util.Date.before(java.lang.Double)"
How do I specify dates in the data field to get around this?

The constructor is not visible
by suddeb
Hi,
I am trying to create a rule:
//list any import classes here.
*import com.sudipta.sample.Student;
import com.sudipta.sample.PassType;
rule "If Student's age is less than 19"
when
$student : Student(age<19)
then
System.out.println("Child Pass for "+$student.getName());
System.out.println("Creating PassType Object..");
insert(new PassType($student,"Child"));
end*
I am getting the error:
The constructor PassType(String) is not visible
Whereas in the PassType class, the constructor is defined like:
*public class PassType {
private Student student;
private String type;
PassType(Student student, String type){
this.student = student;
this.type = type;
}
......
}*
Can anyone please help me why this error is coming? Thanks.
Regards,
Sudipta

[BAD Bug]: Re: Drools Expert does not sort integers correctly
by Wolfgang Laun
This BAD bug was introduced on the way from 5.4.0 to 5.5.0 (and seems
to have sneaked into 6.0.0 as well).
Only 5.4.0 and predecessors work as expected.
Damage control? How far can 5.5.0 be trusted?

Unable to modify collection fields in Guvnor Test Scenarios
by dmoreno
I have imported a POJO model jar in Guvnor. The jar is made up of typical
data transfer objects, with properties accessible through getters and/or
setters.
Some of those properties are collections, only accessible through getters,
and therefore, they can only be modified through the usual collection
methods: add, remove, and so on.
Then I have created some business rules using facts from the imported model.
What I haven't found is a way to set up such collection fields in the Given
section of a Test Scenario. Trying to assign a literal value gives the
error:
"Unable to run the scenario.
[Error: could not access/write property …]"
Does anyone know any way to achieve that goal? Bear in mind that I don't
have access to the POJO model source code.
Thanks in advance.
