Why is solving a partial puzzle much slower than generating one from scratch?
by aitchnyu
I am making a 3x3 Sudoku solver with Drools planner. The planning entities
are the digits. The problem facts are the rows (planning variable) and
columns.
When I set Drools Planner to solve a problem where no digit is initialized,
it gives a perfect solution in ~15 secs. But when I set a few digits as
initialized, it never finds a solution. It always lists 8 hard constraints
broken on termination.
I implemented the moves as:
if(digit.getFixed()==false){
moveList.add(new RowChangeMove(digit, toRow));
}
If the digit is fixed, dont make a move object for it.
Earlier, I implemented it in isMoveDoable: if the digit.getFixed() is true,
it returns false. Both do not work.
20:31:13.442 [main] INFO o.d.p.c.l.DefaultLocalSearchSolverPhase - Phase
local search finished: step total (978), time spend (60061), best score

20:31:13.442 [main] INFO o.d.p.core.solver.DefaultSolver - Solved: time

Help
by seagull
Hi everyone,
I am new to drools.net and I am testing some basic commands but can't seem
to find help anywhere! I am trying to print the contents of a variable but
for some reason, the contents are not printed! The first line (i.e. hello)
on the other hand is being printed.. Is there a common mistake I may be
doing?
Thanks!
rule "testing"
when
p: Person (name == "john")
then
Console.WriteLine ("hello");
Console.WriteLine (p.name);
end

using Drools global variables inside operator timer(int: <variable name> s)
by skatta1986
Hi,
I want a global variable inside a timer instead of hard coding.
-------------------------------------------------
ksession.setGlobal( "timeout", new Integer(10));
---------------------------------------
*
Improper (not working) rule: *
global Integer timeout;
rule "tmeout case"
timer( int: timeout.intValue() s )
when
$request : EventRecord(eventType == "EVENT_REGISTER", user ==
"katta") from entry-point "AggStream"
and not (EventRecord( eventType == "EVENT_RESPONSE", ", user ==
"katta", this after[ 0s, 10s ] $request ) from entry-point "AggStream")
then
System.out.println("-- timeout for user : "+ $request.getUser() );
end
------------------------------------------------------
This new rule doesn't give any error but it is giving unexpected result.
For example if a fire only one EventRecord(eventType == "EVENT_REGISTER",
user == "katta") into the working memory, then after 10seconds I should get
timeout as per my requirement.
But for the above rule as soon as I fire the EventRecord it is giving as
timeout.
Please help me in this regard

Guvnor data enumeration issue
by GPatel＠tsys.com
I am trying to use data enumerations and running into a problem. Following
the Vehicle engineType/fuelType data enumeration example in the Guvnor
manual, I created the following enumeration list and it works:
'Vehicle.engineType' : (new test.VehicleHelper()).getEngineTypes()
'Vehicle.fuelType[engineType]' : '(new
test.VehicleHelper()).getFuelTypes("@{engineType}")'
VehicleHelper:
------------
public class VehicleHelper {
public List<String> getEngineTypes(){
List<String> engineTypes = new ArrayList<String>();
engineTypes.add("Petrol");
engineTypes.add("Diesel");
return engineTypes;
}
public List<String> getFuelTypes(String engineType){
List<String> fuelTypes = new ArrayList<String>();
if("Petrol".equalsIgnoreCase(engineType)){
fuelTypes.add("ULP");
fuelTypes.add("PULP");
}
else if("Diesel".equalsIgnoreCase(engineType)){
fuelTypes.add("BIO");
fuelTypes.add("NORMAL");
}
else{
fuelTypes.add("Default Fuel 1");
fuelTypes.add("Default Fuel 2");
}
return fuelTypes;
}
}
Above works as expected.
Problem:
I want to only have an enumeration on Vehicle.fuelType that depends on the
value of engineType, without specifying an enumeration on engineType. So,
I took out the first line in my enumeration list so that it is now:
'Vehicle.fuelType[engineType]' : '(new
test.VehicleHelper()).getFuelTypes("@{engineType}")'
But that does not work. When I create a rule, VehicleHelper.getFuelTypes
does not get called and the dropdown for fuelType is not a list.
How do I get this working?
Thanks

Hi,
My application works fine with Drools v 4.0.7. However, when I run my

Rule to load facts with pagination
by mariofox
Hi.
I'm running drools in a project with millions of facts to process. My memory
doesn't allow me to load all of my facts, so I have to load N objects at
once, then start over with next N objects, and so on.
Is it a good idea to let Drools to manage Pagination? I mean, create rules
in Drools with the purpose of loading facts?, or should I have to do this by
executing a Drools session from java in a loop?. My main goal is
performance.
Thanks!

upgrading drools-server 5.0 to drools-camel-server 5.4
by bhochhi
After 2 years, I am trying to upgrade from drools 5.0 to latest. The way we
are using the drools: the client apps(in c# and ruby) sends the request to
drools-server 5.0. This execution server gets the rules .pkg file from
guvnor using the properties files that map rules package at guvnor and
response with output of rules execution. Unfortunately, the new execution
server doesn't seems to work same way as the new one is completely
different. I deployed drools-camel-server-5.4.war and saw how test.jsp is
working. Then I changed knowledge-service.xml to replace the local drl
resource to remote pkg at guvnor as follows:
<drools:resource type="DRL" source="classpath:test.drl"/>
to
<drools:resource type="PKG"
source="http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/test/ex"
basicAuthentication="enabled" username="admin" password="admin" />
When I ran the test.jsp, I got exception, snippet below. There were few
other warning exceptions too, but not sure which is cause this problem. To
make my question short, I want to know is there at quick example or docs
that explain how I can use drools-camel-server to response the
actions(output of execution) to external app that sends the request with
conditions, where camel server gets the rules pkg from guvnor? I have create
the jersey based webservice to do exactly the same, but I want to understand
how this new camel-based server works. I appreciate any kind of your help.

Some problems with Deploying drools-camel-sever 5.3.x in Weblogic 10.x
by ndipiazza
Hey everyone,
We have been trying to deploy drools-camel-server-5.3.x.Final.war from
droolsjbpm-integration-distribution-5.3.0.Final on WebLogic 10.3.3.
We hit a series of issues, of which I've opened up some issue tickets to
address:
1) strict web application container complains about web.xml (JBRULES-3403 -
https://issues.jboss.org/browse/JBRULES-3403) - web.xml needs to be
re-arranged to get it to work in weblogic 10.x.
2) There seems to be duplicate JPA persistence units
(https://issues.jboss.org/browse/JBRULES-3404)
I also experienced two other issues that I do not feel comfortable putting
on the issue tracker because they may be weblogic-specific:
3) When I tried to run a SOAP UI test on the drools server in Weblogic
10.3.3 I get this:

Seems to be two possible ways to solve this (have not tested these yet!)
Option One: Use axis.jar instead of saaj-impl.jar
1. add axis.jar file to bea class path
2. in startWebLogic.sh/cmd
set JAVA_OPTIONS=%SAVE_JAVA_OPTIONS%
-Djavax.xml.soap.MessageFactory=org.apache.axis.soap.MessageFactoryImpl
Option Two: Make a code fix to allow the saaj to function
Follow the below steps to resolve "UnsupportedOperationException"
a. Set classpath to latest saaj-impl.jar in startweblogic.cmd
b. Set the below 2 system properties in code.
System.setProperty("javax.xml.soap.MessageFactory","com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl");
System.setProperty("javax.xml.soap.SOAPConnectionFactory","weblogic.wsee.saaj.SOAPConnectionFactoryImpl");
c. Note that the above 2 classes are available in the saaj-impl.jar which i
have used and set classpath in step1. If you are using different version of
saaj-impl.jar, set the exact "MessageFactory" and "SOAPConnectionFactory"
classes which are avilable in your saaj-impl.jar. (Just extract your
saaj-impl.jar and findout the exact classes).
Obviously we cannot expect Drools team to make any code changes with respect
to WebLogic, so I would imagine trying Step 1 is the best way to go.
4) The drools-camel-server.war’s test.jsp apparently runs an example that
uses a Camel route leading to a REST web service. This does not work for me
either off the bat:

Apparently the camel endpoint did not deploy at all, or something.
I'm wondering what of these issues are totally specific to WebLogic, and
