Case Studies and Success Stories
by Stephen Garvey
Hi everyone,
I hope someone can help me or point me in the right direction. I'm looking
for some case studies on how organisations successfully used Drools.
Organisations like those mentioned on the "Sightings" page. I've been
digging around the site(s) for the past couple of days and have found Red
Hat success stories for jBPM etc.->
http://customers.redhat.com/category/red-hat-jboss-solutions/jboss-enterp...
I was wondering if there was anything like these for Drools, maybe
explaining how people have successfully used Expert and Flow together. I was
at a conference earlier this summer where Mark Proctor gave an overview of
all things Drools and he mentioned some very interesting work going on with
US Navy Healthcare. Are there any of these types of case studies online?
Thanks in advance,
Stephen

Can I create sub packages in Guvnor
by Harshit Bapna
Hello All,
I have gone through the Guvnor UI and I couldn't find a way to create sub
packages under parent package.
for ex: Under package Mortgage, I want to create subMortgage.
*Also I found a method createSubPackage in RepositoryService but not able to
get the UI way to create a subpackage.*
/**
* This creates a package of the given name, and checks it in.
* @return UUID of the created item.
*/
public String createSubPackage(String name,
String description,
String parentPackage) throws
SerializationException;

Re: [rules-users] Guvnor 5.1: Can't open assets - "Unable to validate package configuration"
by Scott Mayne
My apologies, I should have looked a little deeper. The Guvnor Event Log showed I was missing a class in my POJO Model JAR; I fixed that and now everything is working fine.

Hi all,
Using Guvnor 5.1, I'm unable to open assets and get this message:
"* Unable to validate package configuration (eg, DSLs, models) for [CA.FH.BETACAU]. Suggestion completions may not operate correctly for graphical editors for this package.
* Unable to get content assistance for this rule."
I've searched around and it seemed like it might be related to
https://issues.jboss.org/browse/BRMS-425
so I gave the user admin, package.admin and package.developer permission for everything, but it still pops up the same error. Is there any workaround/explanation/quick fix for this behavior?

Drools - Repeated Events and Temporal Relations
by rodih
Hi, In general I am writing rules for events which equal(by attributes
values) events can occur any time in consecutive manner(every second). I
want to fire rules for matched events only on an hourly bases.
In more details: I want to fire a rule when an event is inserted for the
first time (not exist yet) OR when an event is inserted and if and only if
equal events are already inserted to the working memory BUT the newest of
them is at least one hour ago old.
What is a reasonable way of writing a rule of that kind, taking events
duration will be 24H
Thanks

Re: [rules-users] "Negative" Rules
by Wolfgang Laun
Have you looked at insertLogical()?
"Changes made" is a very general term, could be anything...

Automatic unsubscribing from a Guvnor resource
by Chris Selwyn
My Guvnor is setup to save its repository in an Oracle database.
However, the DBAs have a schedule that takes the database down at night
for backup.
I am finding that, if I set up the ResourceChangeNotifier/Scanner system
then the resource gets unloaded from the KnowledgeBase when the database
is down.
Is this really a sensible behaviour?
I would like to think that there would be a distinction between the
resource disappearing from the repository (in which case it would
expected that the rules disappear from the KB) and the repository not
being accessible (in which case I would hope that the rules would remain
cached in the KB).
I am using JBoss Rules 5.0.

Updated rules recovery from rule engine
by aditya chitre
Hi All,
We are using drl files to load the rules in the rules engine. In our
application, we can dynamically add, modify and delete rules from the rules
engine. Is it possible to get these updated rules back into a text file from
the rules engine using java?

About ExtensibleXmlParser
by tangrui.cn＠gmail.com
Hi list,
In the method resolveSchema of ExtensibleXmlParser class, I think there's a
problem.
I'm using a changeset.xml, which has such a header
<change-set xmlns="http://drools.org/drools-5.0/change-set"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://drools.org/drools-5.0/change-set *
/META-INF/schema/change-set-1.0.0.xsd*">
I want to fetch the xsd file from the path /META-INF/schema, but failed.
According to the method statement following, to find a xsd file name, the
systemId was substring-ed using lastIndexOf method. In this case no matter
what path I use to replace the bold text, only change-set-1.0.0.xsd will be
picked. Then the method will find the file under /META-INF, META-INF and
class path. That means even I've written the path
/META-INF/schema/change-set-1.0.0.xsd, but /META-INF/change-set-1.0.0.xsd
will be used.
String xsd;
int index = systemId.lastIndexOf( "/" );
if ( index == -1 ) {
index = systemId.lastIndexOf( "\\" );
}
if ( index != -1 ) {
xsd = systemId.substring( index + 1 );
} else {
xsd = systemId;
}
