drools error: Unable to create restriction
by sam
I am getting the following error when running a drl script:
Unable to create restriction '[QualifiedIndentifierRestr:
Anyone can throw more light on what the issue is?
Here is my complete test set up:
public class InnerBean {
private int testVal = 100;
public int getTestVal() {
return testVal;
}
public void setTestVal(int testVal) {
this.testVal = testVal;
}
}
public class ValidationBean {
private int actualTestVal = 200;
private InnerBean innerBean= new InnerBean ();
public int getActualTestVal() {
return actualTestVal;
}
public void setActualTestVal(int actualTestVal) {
this.actualTestVal = actualTestVal;
}
public InnerBean getInnerBeanl() {
return innerBean;
}
public void setInnerBeanl(InnerBean argInnerBean) {
innerBean = argInnerBean;
}
}
The drl script is
package droolsbook.dsl;
import com.wellsfargo.mortgage.camr.model.hibernate.*;
import com.wellsfargo.mortgage.camr.model.service.drools.*;
rule "Threshold rule 1"
when
$bean: ValidationBean ( actualTestVal > innerBean.testVal )
then
--failure
end
The ValidationBean ($bean) is inserted into drools working memory.
Thanks in advance
Sam

Merging two XML rules into a single XML file
by mcbonz
Hi All,
I'm currently trying to merge two (or more) rule packages in XML syntax into
a single XML Document.
I tryed to use a PackageBuilder to join multiple PackageDescr. My problem is
that the XmlDumper expects a PackageDescr and there seems to be no way to
get a PackageDescr out of a PackageBuilder.
Here is what I tryed:
Document ruledom;
XMLOutputter outputter = new XMLOutputter();
String rulestring = outputter.outputString(ruledom);
ByteArrayInputStream in = new ByteArrayInputStream(rulestring.getBytes());
PackageDescr pack = xmlr.read(in);
builder.addPackage(pack);
XmlDumper dumper = new XmlDumper();
dumper.dump(?);
Is there any possibility to get a PackageDescr out of the PackageBuilder?
Is there another way to merge XML rule files?
Any help is appreciated
Thanks, Ben

Rule Flow in Guvnor 5.2
by Sumeet Karawal
Hi,
Is there a possibility that we can create/edit a RuleFlow in Guvnor 5.2.
I have read the documents where it mentions the creation of Rule Flow in
Eclipse IDE and then importing the .rfm file in Guvnor, is there a way that
we can have the whole functionality of creating/editing Ruleflow in Guvnor
only. I searched for it and found something related to Orxy designer but
not able to get the whole thing. Can anybody help me on this.
Thanks & Regards,
Sumeet

Deployment Problem with .pkg Files
by Oli Blub
Hi to all,
when i found out that the build in selector only works for binary package i
wanted to switch. So i downloadet the .pkg File, copied it to the execution
server and changed the changeset to :
<add>
<resource source="classpath:/bhc_material/f/Test.pkg" type="PKG" />
</add>
By restarting the server i can't get it work. For .drl File it works fine. :

[guvnor] web decision table/action with formula value instead of literal
by dhartford
Hey all,
I'm still new to Drools, so maybe my expectations are incorrect, but I
thought I would ask --
In the guvnor (5.2 final) web decision table editor, the 'action' columns
seem to only accept literal values and not allow formula/expression based
values.
Is this intentional? I've made a bunch of normal rules, but from a 'batch
edit/review' where there are a lot of similarities I thought I would put
them in a Decision Table...but the actions (on specific fields) are all
formula/expression values, not literal.
thoughts? thanks!

Dummy question from a new comer
by cross.cy
Hi, I only started using Guvnor recently. Just wonder if anyone could clarify
one question. A good benefit of using Guvnor to manage rules is to decouple
the rules from application code. However, the RHS of some rules may involve
actions related to other logic classes in application. For example, there's
a rule that sends out an email in the action, which uses methods defined
elsewhere in the project, and these should not be known by Guvnor. So my
solution for that is, create a declarative model containing an "Email" fact
in Guvnor. When the rule fires, logical insert an "Email" object. And back
in java code I'll try to check if there's an "Email" object created after
the fireAllRules() call. If there is, call my email sending method.
Is this the right way? If so, what's the best way to look for the newly
created "Email" object in Java code? There are methods to getFactHandles()
and getObjects(). Are they the area to look for?
Any comment will be highly appreciated!
Yu

Guvnor Repository Directory with Replicated Database
by Robert Morse
Our Seam 2.2.x application uses Drools 5.2 and Guvnor 5.2 running under JBoss 5.1.0.GA. We use an external MySql database set up in a master slave configuration. The repository.xml file points to the master MySql database (obviously).
Here's my question: Let's assume the database master fails, and we promote the slave so it's now the master. The repository.xml file would now need to point to the slave's database instance. Does anything in the Guvnor created repository directory need to be modified? Is it safe to switch simply by changing the values in repository.xml?
Thanks.
