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.

wierd error : illegal bytecode sequence - method not verified
by arrehman
Hi,
I have been using Drools 5.3.0 core successfully in my grails/groovy/java
project. The two dependency that are mentioned in my buildconfig file
(BuildConfig.groovy) is :
//drools
runtime 'org.drools:drools-core:5.3.0.Final'
runtime 'org.drools:drools-compiler:5.3.0.Final'
runtime 'com.sun.xml.bind:jaxb-xjc:2.2.4'
Now I wanted to switch to Drools 5.5.0. What I did is I merely changed the
version number above.
//drools
runtime 'org.drools:drools-core:5.5.0.Final'
runtime 'org.drools:drools-compiler:5.5.0.Final'
runtime 'com.sun.xml.bind:jaxb-xjc:2.2.4'
However the tests that were working before are failing now, with some weird
error. I am guessing this has to do with conflicting jars or missing jars or
whatever and not drools.
=============== DEBUG MESSAGE: illegal bytecode sequence - method not
verified ================
Jan 17 2013 14:19:57 ERROR business.service.RulesService - Error executing
validation drools rules Exception executing consequence for rule "Sale Price
Not <= 20 " in business.rules: java.lang.NullPointerException
Jan 17 2013 14:19:57 ERROR business.service.AddsService - Error executing
validation drools rules Exception executing consequence
Any idea what is going on?
Thanks,
Arrehman

Guvnor model with 'Comparable' not working
by Sandjaja, Dominik
Hi everybody,
I use Guvnor 5.4 and have a model which consists of classes and subclasses.
@Entity
public class TestClass {
@Id
private long id;
@Embedded
private TestEmbeddable embedded;
}
@Embeddable
public class TestEmbeddable implements Comparable<TestEmbeddable> {
@Column
private String testProperty;
@Override
public int compareTo(TestEmbeddable o) {...}
}
Now, in Guvnor I use the guided Editor and create a new WHEN condition:
There is a TestClass with:
embedded ...
Usually, when I click on "embedded", I can select
Apply a constraint to a sub-field of 'embedded': Show sub fields ...
This line does NOT show if that subclass (here: TestEmbeddable) implements Comparable. It does however work if I don't use Comparable or if I select TestEmbeddable directly (which I can't as I don't inject those into my working environment).
Is this a known bug? I couldn't find anything about this.
TIA
Dominik

Deploying Guvnor on JBoss AS fails with FileNotFoundException
by Thomas Söhngen
Hello,
I am trying to deploy Guvnor 5.5.0.Final on JBoss AS 7.1.1.Final
(running in a Ubuntu VM). I rename the
"guvnor-5.5.0.Final-jboss-as-7.0.war" to "guvnor.war" and copy it in the
"standalone\deployments" folder of the AS. The AS starts the deployment,
but fails immediately with the following error:

Anyone got an idea, why this happens?

Guvnor 5.5 being WIERD
by starfish15
Hi,
I have been using Drools 5.2 from sometime. However we upgraded to Drools
5.5. However am facing some issues with the ACTION facts.
Earlier, using StatelesSession, we were able to use composite Command
BatchExecution and retrieve the result facts easily. When we are trying the
same thing in Drools 5.5, the result facts are some new objects i believe.
Do let me know if my Q makes sense or should i give some more info.
Regards,
Starfish

NullPointerException at org.mvel2.ast.IntSub.getReducedValueAccelerated
by Michiel Vermandel
Hi,
When starting the planning solver I sometimes get the error as listed beneath.
I think it happens about 1 out of 5 runs.
It doesn't seem to have much influence on the solving process as everything continues normally (I think).
I do not use any mvel expressions to my knowledge.
Anyway, it would be nice to understand why this happens and how to get this resolved.
