Guvnor problems...
by des4900
I am working with Guvnor/Drools 5.5.0, jBPM 5.4.0 on Win7 64 bit, JBoss 7.1.1
First Problem:
1. I have a rule in the global area, e.g., Rule1
2. I create a new rule in a package by importing Rule1 from the global area
3. I realize that I imported the wrong rule.
4. How do I remove Rule1 from the package? If I archive it from the
package, it also archives it from global, which I don't want to do since it
has been imported into many other packages. If I archive it from the
package anyway and then restore it, it reappears in the global area, and
also in all of the other packages that it was a part of. The only thing I
have found that works is to copy the rule, archive it, delete it, and then
import the copied rule into all the packages where the original rule
actually belongs.
Second Problem (which I got into by trying to deal with the first one
above):
1. I have a rule in the global area, e.g., Rule2
2. I rename Rule2 to Rule3
3. I also have a different rule in a package named Rule2
4. I archive and delete Rule 2 from the package, and it no longer appears
in the archives, nor in the package. I save the package, close it, stop and
restart JBoss, and check again, and it is not in the archives nor in the
package.
5. I try to copy Rule3 from the global area to this package giving it the
name Rule2 (the same name as the rule I archived and deleted) and somehow
Guvnor thinks Rule2 is still there.
6. I get an error (apparently Guvnor thinks the rule is still there):
Error

Drools as a Webservice
by abhinavgupta
Hi,
I am new to the Drools , i wanted to expose rules as a webservice using
Axis2.
what i have done is that
1. I have created a drools Project (working fine on eclispe) export all
files in jar
2. Placed the jar file in C:\Program Files\Apache Software Foundation\Tomcat
7.0\webapps\axis2\WEB-INF\lib directory
3. Created a new Dynamic java project with axis2 facet.created a class with
**
package in.abhi.ws;
import java.math.BigDecimal;
import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderError;
import org.drools.builder.KnowledgeBuilderErrors;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.runtime.StatefulKnowledgeSession;
import com.sample.SaleItem;
public class Test {
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("KanasSalesTax.drl"),
ResourceType.DRL);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() > 0) {
for (KnowledgeBuilderError error : errors) {
System.err.println(error);
}
throw new IllegalArgumentException("Could not parse knowledge.");
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
}
public BigDecimal salesTax(String taxState, String typeItem) {
BigDecimal taxCal = null;
try {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase
.newStatefulKnowledgeSession();
// Non-prescription item
// Expect $1.89 for the tax
SaleItem item1 = new SaleItem();
item1.setPurchaseState(taxState);
item1.setItemType(typeItem);
item1.setSalesPrice(new BigDecimal(29.95));
ksession.insert(item1);
ksession.fireAllRules();
taxCal = item1.getSalesTax();
System.out.println(item1.getPurchaseState().toString() + " "
+ item1.getItemType().toString() + ": "
+ item1.getSalesTax().toString());
} catch (Throwable t) {
t.printStackTrace();
}
return taxCal;
}
}
**
4. Then created a bottom up java bean webservice of it using the same above
class.
5. Wsdl is generated
i am getting the error response on eclispe console while testing by soap-ui

ClassCastException using memberOf operator
by Marco Malziotti
Hello
I am a beginner in Drools 5.1.1 and try to use 'memberOf' operator.
Simply I want check whether a short field 'f' (belonging to Item class)
is a member of an array 'a': retrieved by a function 'makeA'.
In my .drl file I try with :
function Short[] makeA() {
return (new Short[] {1, 2, 3} );
}
rule "chek"
when
a: Short[]() from makeA()
i: Item ( f memberOf a )
then
... 'f' is member of array 'a' !
end
I have following stack trace:
java.lang.ClassCastException: Can't check if an attribute is member of
an object of class class java.lang.Short

Help to implement my 1st planner
by André Rezende Fróes de Moraes
Hello everyone, i'm trying to implement drools planner for my paper and it
is proving very hard taking in consideration that i never user it before.
I was able to reproduce the examples, even though i got very confused, but
i undestood some things, but i'm really lost of how to implement my own
project/rule.
My paper is about service, I don't really know how to define it, but i'll
try to explain.
A given company receive several requests of maintence, repair, etc, all the
time, and it have a number of people to solve that, these technicians. It's
something like the nurse roaster but waaaay to simpler.
An issue can pop at any minute, it have a starting time and an estimated
time to be acomplished.
The technician have work for a fixed amount of time, but he have the start
time and the end time of work, that I want to use to assign the issue.
I've created the class Technician
Technician

[Error: incompatible types in statement: boolean (compared from: class be.axi.planner.domain.Task)]
by Michiel Vermandel
I am using Drools Planner 5.5.0.Final.
During the running of a unit test I sometimes get a crash with stack-trace shown beneath.
It does not happen all the time, just now and then.
But if it happens the process terminates and no solution is reached.
Any ideas on this?
The stack-trace does not show a lot on which rule is failing...

Can SolverFactory receive the plain xml?
by André Fróes
Can I provide the plain xml code to a SolverFactory?
SolverFactory solverFactory = new XmlSolverFactory(<<xmlHere>>);
I know that I can provide the path to a config file.
