[rules-users] JBoss As 7 with guvnor 5.4 - package build error: cannot resolve identifier
Hi, I expanded the guvnor.war/WEB-INF/libs with new library demo.jar. In all rules the access on every Class in demo.jar is possible with x.y.z.DemoClass. But the access to a public subclass in the class x.y.z.DemoClass x.y.z.DemoClass.DemoSuclass does not work, causes cannot resolve identifier on trying to build the package in guvnor. Any idea?

I'm still pretty new to drools (5.4.0 final) and I would like to see what Drools does; rules validation, MVEL expression evaluation, etc. There is a webpage that says that in order to activate logging I need to add a line to my log4j.xml: /http://docs.jboss.org/drools/release/5.4.0.Final/drools-planner-docs/html_single/index.html#d0e2947 / First remark is that the XML is old style log4j; the current XML uses loggers and levels instead of category and priority.

Re: [rules-users] Calling a function from When part
Hi FrankVhh,
The above approach you suggested works,
But the problem is it continuously hits this method when it satisfies the
rule in the method I have a DB call, so it creates some problem.
For eg: -
function boolean sampleFunction(){
//makes a DataBase call
System.out.println(1234);
return true/false;
}
rule sample1
when
//condition 1
then
System.out.println(abcd);
//some action to satisfy condition 2
System.out.println(mnop);
end
rule sample2
when
//condition 2
sampleFunction();
then
//some action
System.out.println(xyz);
end
O/P
abcd
1234
1234
1234
1234
mnop

1234
1234
1234
1234

Is there any way to tackle this. As in by using salience or something.?

Re: [rules-users] log4j has no logging, but setup according to documentation
Drools Planner logs to slf4j, from which you can configure logging with log4j or logback (and others) to log to whatever and however you need it. Drools Expert (the rule engine itself) does not log to anything by default. A) You can add KnowledgeRuntimeLoggerFactory.newFileLogger(...) but that will not give you the flexibility of a logging framework (such as rolling files, backup files, controlling verbosity by package, controlling verbosity by INFO/DEBUG/TRACE, log pattern configuration, ...). B) You can implement your own WorkingMemoryLogger and pipe that to slf4j, but WorkingMemoryLogger will probably not log anything of other drools expert systems, such as the KnowledgeAgent, changeset problems, xls to rules converstion, ... Those messages will still be send to System.out.

[rules-users] Avoid caching method results within non fact objects
Good day everyone, I'm having a problem here and I'm not sure if I'm using
the right approach.
Currently I have a couple of rules where I inject A LOT of objects as facts.
These objects change their states quite commonly and I have to make
decisions when the previous state has a particular value comparing it to the
current state. Something like this (just an example, sorry if there are
typos)
rule Interesting Event
when
$currentFact: CurrentFact(state==somethingNew)
$previousFact: PreviousFact($currentFact.id == id state==somethingOld)
then
//do something
//update previousFact to reflect the state of the newFact
end
The problem that I had with this is that I had SOOO much facts within the
rules session (thousands of objects with a lot of data that I need within
the session too) that the fireAllRules method started to take too much time
to complete.
So, what I did is to store the previous facts of the objects within a
Wrapper class that contains a hashmap with all of these states.
Something like:
PreviousStateHolder{
private static HashMapString,PreviousFact previousFacts;
public void insertPreviousState(){
...
}
public boolean containsPreviousState(CurrentState currentState){
...
}
public boolean deletePreviousState(){
...
}
.. other management methods
}
And my new rules look like
rule Interesting Event
when
$currentFact: CurrentFact(state==somethingNew)
$previousFact: PreviousFact(state==somethingOld)
from
PreviousStateHolder.retrievePreviousState($currentFact)
then
//do something
//update previousFact to reflect the state of the newFact
end
The problem is that drools caches the result returned by the
retrievePreviousState() method, so, it does not matter if the
PreviousStateHolder member changes; drools always caches the result. I have
tried to put my invocations within eval() but I still get the same problem
(cached results).
I know they are being cached because I put a breakpoint within the methods,
and the first time the fireAllRules gets executed, they get hit. But then,
the consequence of these rules keep getting executed even if the
retrievePreviousState() does not reflect the value needed to do so.
Am I doing something wrong?? Is there another approach that does not involve
inserting all of these states as facts within my session??
Thanks a lot in advance

Re: [rules-users] Avoid caching method results within non fact objects
The alternative you're attempting using from is potentially less efficient
than the first one you tried. :)
Can you alter the CurrentFact objects to hold current and previous state? That
way you avoid the matching step altogether.

$currentFact: CurrentFact(state==somethingNew, previousState==somethingOld)

no-loop
salience -1
when
//condition 1
then

//populate a list

rule two
salience -2
when
eval(foo(pass the list that we populated in the above rule))
then
system.out.println(two in);
//do some action
system.out.println(two out);
end
O/P we are getting: -
foo
one in
foo
foo
one out
two in
two out
Expected O/P
one in
one out
foo
two in
two out
Please suggest a way to do the same.
