Re: [rules-users] Insert a fact into drools server from a web application or java application

[rules-users] Drools5.2.2 integration with scala2.9.0.1
Hi,
I am new with Drools. I am integrating Drools with Scala. I am trying the
project given at
http://www.gettingcirrius.com/2010/12/using-jboss-rules-drools-in-scala.html
http://www.gettingcirrius.com/2010/12/using-jboss-rules-drools-in-scala.html
.
I have made a small change in the code to supply the Drools rule file as
given below:
File f = new File("WeatherRules.drl");
kbuilder.add(ResourceFactory.newFileResource(f), ResourceType.DRL);
The code is running fine and there is no error but the rules are not
working. The output I got is:
Creating Knowledge Session
Creating and insertng Temperature
Firing all rules
It seems that the configured rules are not working. The dependencies I am
using in for is:
Scala: 2.9.0.1
Sbt: 0.7.7
jaxb-xjc: 2.2.4-1
drools-core: 5.2.0.Final
drools-compiler: 5.2.0.Final
jxl: 2.6
xstream: 1.3.1
Am I missing something? Please help me to integrate Drools with scala.
Thanks in advance. Any help will be appreciated.
thanks,
Puneet

okay, thank you very much for your replies.

Just fyi, see this post on running jBPM5 on AS7: http://planet.jboss.org/post/jbpm5_on_as7_lightning The web Designer also has support for AS7 with its latest version: http://sourceforge.net/projects/jbpm/files/designer/designer-1.0.0.054/ Once we get Guvnor running on AS7 I am sure we will update the jBPM installer to it for full integration.

Not sure where you got the designer war from (it is hosted on sourceforge: http://sourceforge.net/projects/jbpm/files/designer/ ). Make sure you get the *-jboss.war and rename it to designer.war before deploying alongside the guvnor war. Guvnor currently expects the designer to live on the same host and port right now. Designer is configurable as to where it looks up the guvnor location. In order to change this information you have to deploy designer as an exploded war and edit $jbossas/server/default/deploy/designer.war/profiles/jbpm.xml. The bottom of this file contains section ..you should leave the subdomain as-is and change other attributes as necessary. Just as a note, with jbpm5 installer (http://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.1.0.Final/) puts it all together for you and really is the easiest way to get started with using guvnor/designer/jbpm-console, and saves you the headache with issues like these.

There are troubles with guvnor (because of seam 2 and the way guvnor architecturally (mis)uses it) on JBoss AS 7. We've been trying to quick fix these, but without much luck. Guvnor 5.4 will upgrade to seam 3 (the protype works already, and will use seam correctly) and will run on JBoss AS 7.

This is the proper way of making a constraint on a fact attribute. "getSi"

# Same as above.
You realize that <100 also means <200; if so, both rules will fire and "val"
could be set either way.
