by Ming Fang
Is it possible to make temporal parameters dynamic by using bound variables?
Example:
EventA( this after[ $later ] $eventB)

Re: [rules-users] Drools solver info => provide DSL instead of DRL to Drools Solver
by dmzpippo-drools＠yahoo.it
Hi Geoffrey,
I have modified the LocalSearchSolverConfig class to accept the <scoreDsl> tag.
To use this tag need gonfigure the XML solverConfig file adding the path of Drl file and Dsl file associated in two line consecutive in the configuration file. This code is not the best but is a start....
I send you the code if it can be useful.
I
would also ask when it launches the new version of the solver, and if
this will also include other local search algorithms than Tabu Search
with kind regards,
Marco

Please refer to C:\droolsinst\Drollig\drools-vsm\target\surefire-reports for

Looking in surefire reports at the concerned location, I have

Do you have any suggestions on how to prevent this error?

Null pointer when retracting Event which has an 'after'
by richarda
I wish to have a rule that says, if I get one event, but not another one
after a period, then do something.
But I also want to only do this once..
So, I wrote the rules: (using the eclipse sample project)
declare Message
@role( event )
end
rule "Hello World"
when
$m : Message( status == Message.HELLO )
not ( Message( status== Message.GOODBYE, this after [0s,1m] $m)) ;
then
System.out.println( "Hello" );
end
rule "GoodBye"
when
$one : Message( status == Message.HELLO )
$two : Message( status == Message.HELLO )
then
System.out.println( "Two hellos, remove one" );
retract($two);
end
But, when I run;
Message message = new Message();
message.setMessage("Hello World");
message.setStatus(Message.HELLO);
ksession.insert(message);
Message message2 = new Message();
message2.setMessage("Hello World");
message2.setStatus(Message.HELLO);
ksession.insert(message2);
ksession.fireAllRules();
I get:
Two hellos, remove one

Re: [rules-users] some pointers for solution
by Greg Barton
There are a couple of ways to do this. I'm sure there's a bit more clean way than the example I'm providing, but this should get you in the right direction. It's not 100% rules, because it involves a bit of java collections trickery. (See attached project, collection_DroolsCriteriaMatch.tar.gz)
The heart of it is a single rule:
rule "Match"
when
d : Data()
q : Query( size <= d.size )
Number( intValue == q.size )
from accumulate(
Criteria( this memberOf d, this memberOf q ),
init( int total = 0; ),
action( total ++; ),
reverse( total --; ),
result( total )
)
then
System.out.println("Match: " + d + " and " + q) ;
end
The Data object holds data to be queried, Query objects are asserted to match the Data, and Criteria objects can be contained in either. (With the aforementioned collections trickery that if a Criteria is contained in a Query it can be found in a Data object, but the reverse isn't true. See the Query.contains(Object) method for how that's implemented.)
So the rule above basically says "There's a Data object, and all of the Query objects Criteria are contained in the Data object."
There's an alternate way of doing this using eval and a bit more java fu. See the eval_DroolsCriteriaMatch.tar.gz project attached. This one's probably not optimal, though, as it's basically a brute force check of all Data objects against the asserted Query.
I tried for a while to get a solution working with different criteria types from both Data and Query objects being asserted into working memory, but I couldn't get the accumulate syntax right. Anyone know of a way to do that? (I figure that would get a "pure rules" solution.)

Help in fixing Persistence of a process
by ramram8
I am trying to create a workflow scenario in the GWT console. So what I am
doing is that I am uploading the jar file and the rule flow into the Guvnor
in order to use the scenario in the Gwt Console.
I start a task service alone and start the JBOSS with no problems when
loggin in into the GWT console also there is no errors on the server. Once I
press on Process Definition/Definition List I have the following exception
EXCEPTION -1- on the server but the process appears and when I press on the
start process I have EXCEPTION -2- Please check these exceptions and Please
can you provide help in fixing them
EXCEPTION -1-

Help me improve my rules performance.
by ABRA2
Hi,
I have an example of two rules we use in our project.
Rule CheckStationNumber checks if the station number field is null in
BillingRecord Object which is
stored as a list in AssertionObject object.
Rule AssignBAC gets a value from a static map(we dont want to do database
calls eachtime.so we store the
required values in a static map) and assigns it to bac field in
BillingRecord based
on certain other field values in Billing Record.
So we have around 10 more rules similiar to this pattern and we run this
rule against against
100,000 billing records and the execution time is very long.
I know that i am not supposed to use eval in rules which slows down the
performance. Can you please
suggest me few other ways how i can accomplish these tasks and improve the
execution time?
thanks
ABRA2
