[rules-users] Dynamic facts
Hello everyone, I need some enlightening about Drools "dynamic facts" (a term used in the documentation, for facts that could be updated from outside the rule engine). The current documentation always list the "insert" method of a StatefulKnowledgeSession being able to take an additional boolean argument, stating that the corresponding fact supports the PropertyChangeSupport related methods. However, it seems that this method do not exists anymore for already some time now... After googling for a while it appears that some possible workaround were modifyInsert (apparently removed from the API as well) and the @propertyChangeSupport meta-data annotation, but I didn't manage to make it work (actually I wasn't able to find any reference from it in the API, so I guess that it is also not available anymore). So, this left us with the "session.update" method. Which seems to works great, except that it will invalidate the whole fact into the working memory, even if only some of the fields were changed. Is this some current limitation of Drools? Does it have something to do with those "Shadows Fact"? (that would be somehow immutable?) If we effectively can't fire update targeted to some specific fields, this has probably some big implications on performances (even for simple fact with only a few fields). It would also means that one should always aim at the finest granularity for better performances, by somehow "flattening" the object structure into the knowledge base (which in turn could make complicated to reuse those same Pojo in other frameworks, such as hibernate). Did I miss something? Any feedback deeply appreciated, Thanks! M. H. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] concurrent modification of a rule by more than one user in Guvnor
Hi All, I am currently testing 5.2.0.CR1 version of Guvnor. Can multiple users modify a rule in Guvnor at the same time? what are the issues involved in say, two users trying to change 1. the same row in a decision Table at the same time and saving it. 2. different rows in a decision table at the same time and saving it. Are there any documentation or articles to get more information on concurrent access within Guvnor? Thank You, ram. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] jaxb generated fact loaded into Guvnor throws errors when using the ' is contained in the comma separated list' operator
Hi Mike,
Thank You for your responses.
My apologies.
I did miss copying the closing bracket.the issue still exists though . I
suspect whether the way the code has been generated by jaxb has anything to do
with it.
In the xml, the field is all upper case as
I see that JAXB generated the code as follows.
@XmlElement(name = "ACTIVITYCODE", required = true)
protected String activitycode;
/**
* Gets the value of the activitycode property.
*
* @return
* possible object is
* {@link String }
*
*/
public String getACTIVITYCODE() {
return activitycode;
}
/**
* Sets the value of the activitycode property.
*
* @param value
* allowed object is
* {@link String }
*
*/
public void setACTIVITYCODE(String value) {
this.activitycode = value;
}
rule "Row 1 dds"
ruleflow-group "None"
dialect "mvel"

factClass : FACTCLASS( ACTIVITYCODE in ("A", "B"))

Hello ,
I am using 5.2.0.CR1 version of Guvnor .
I have a jaxb generated class loaded through the model jar into Guvnor to be
used as a fact in the Guided Decision Table editor.
When I use a field ACTIVITYCODE of type String from the JAXB generated class
with ' is contained in the comma separated list' operator, I get compilation
errors.
Unable to Analyse Expression ACTIVITYCODE == "A" || ACTIVITYCODE == "B":
[Error: no such identifier: ACTIVITYCODE] [Near : {... ACTIVITYCODE == "A" ||
ACTIVI }] ^ [Line: 1, Column: 1]
But when I use equal to operator to compare value to just a string value, it
compiles fine.
This rule fails.
3. | rule "Row 1 dds"
4. | ruleflow-group "None"
5. | dialect "mvel"
6. | when
7. | factClass : FACTCLASS( ACTIVITYCODE in ("A", "B")
8. | then
9. | factClass.setRATE( "5.25" );
10. | end
The below rule compiles fine.
3. | rule "Row 1 dds"
4. | ruleflow-group "None"
5. | dialect "mvel"
6. | when
7. | factClass : FACTCLASS ( ACTIVITYCODE =="A")
8. | then
9. | factClass.setRATE( "5.25" );
10. | end
Is this issue being caused by jaxb generated class? If so, is there a way to
fix this problem?
When I use a regular pojo that is not jaxb generated, the
is contained in the comma separated list' operator works fine.
Can someone provide any direction or thoughts on this?
Thanks,
Ram

Re: [rules-users] priority based on object properties
But here comes another problem... I used "salience (-$path.cost)" in the rule for propagating current shortest paths on a node to neighboring nodes. At first, it worked great, as in the log I see routes with smaller costs being propagated. But later on, I see the progress slowing down quite a bit. My guess is that the sorting based on (-$path.cost) takes longer and longer as the number of objects increases - now my java process takes about 8GB of memory. One idea is to use some sort of bucketing, such that I duplicate the propagation rule from one to, for example, five, and each of the five rules would be applied on a subset of the paths with a particular range of costs. This might work, but has the downside of needing the input of some data statistics (for proper bucketing, for example.) Any ideas on this?

[rules-users] priority based on object properties
Hi all, I am curious if we can inform Drools' execution based on properties within objects. In particular, the salience value is defined for each rule, in the sense that rule A has priority over rule B to execute. I am wondering if we can define some kinda of salience metric, such that object X has higher priority than object Y to be executed in the same rule. To give an example, I am (still) playing with implementing shortest path using a few rules. I have a rule for selecting a shortest path on a node (among all the paths received from its neighbors) to a source node, and another rule for propagating the shortest path on a node to neighboring nodes. When I have many nodes in my graph, I found that the paths propagated (via the second rule) are not always the shortest, while Dijkstra's algorithm always "propagate" from the node with the shortest distance to the source. The effect is that my rules are wasting most of the time propagating paths that would be dropped in the end anyway... Any ideas?

Re: [rules-users] Global variable in LHS
That's right.. globals are usually used to access to external services and
usually you don't want to do inferences over that global references. Global
are not facts. If you want to do inferences create a fact :)

Re: [rules-users] Global variable in LHS
Don't use a global, instead create a new fact type "Global" having a single
field globalVariable (type object will probably do), then you can pretty much
write what you have below (once you add the missing bracket).
Alternatively you may be able to do something like eval(Arrays.asList("X",
"Y").contains(globalVariable))

[rules-users] Global variable in LHS
Hi everybody,
I would like to analyze a global value in the LHS of my rule without using
an eval, something like this:
global String globalVariable;
rule 'SI-002-NAD-6'
salience 5000
when
global (globalVariable in ("X","Y")
then
logger.log("[SI-002-NAD-6] Debe colocar la información del propietario
del
medio de transporte.");
end
I cant use eval because it doesnt recognize the keyword "in", for example
this code would throw me an error in the validation
global String globalVariable;
rule 'SI-002-NAD-6'
salience 5000
when
eval (globalVariable in ("X","Y")
then
logger.log("[SI-002-NAD-6] Debe colocar la información del propietario
del
medio de transporte.");
end
any suggestions? thanks so much for your help :)

[rules-users] how to invoke rest service on drools server with serialized objects
I installed drools-server (5.2 final) in tomcat and was able to invoke the sample Soap service using SoapUI using Salaboy's excellent blog post instructions. I have modified knowledge-services.xml to add my rule base using a knowledge agent, and changed camel-server.xml to marshal/unmarshal using serialization.

Re: [rules-users] PDFs of Drools 5.2.final: pictures too big
The PDF is generated from DocBook source, as is the "HTML" and "HTML single" versions of the documentation. There are some known compile-time issues scaling the images correctly for the PDF. Feel free to either:- (a) Fix the image scaling yourself and contribute back to the project (b) Attach a list of all affected images (what user-guide, what section, what image etc) to a JIRA for us to eventually look at.

Use the html version at this time.

Re: [rules-users] errors of deploying Guvnor 5.2.0 to JBoss 7.0
Thank you Jervis, I'll try your suggestions and see if it fixes it. I did some further research today. JBoss AS 7 uses a new way of class loading. By default, the modules are isolated. The guvnor war file I tried to deploy is guvnor-5.2.0.Final-jboss-as-6.0.war. In the pom.xml I found the following section: " org.apache.cxf cxf-rt-frontend-jaxrs 2.3.1 ... " Also in JBoss AS 7 modules the org/cxf folder is empty. So i suspect the dependencies need to be explicitly specified in the MF file.

Re: [rules-users] errors of deploying Guvnor 5.2.0 to JBoss 7.0
Notice this line: org.jboss.as.jaxrs.deployment.JaxrsScanningProcessor.checkDeclaredApplicationClassAsServlet(JaxrsScanningProcessor.java:310) So the problem is JaxrsScanningProcessor can not load CXFNonSpringServlet. This is because AS 7 JAX-RS is configured to use RESTEasy by default. Two options I can think of: 1. Modify modules/org/jboss/as/jaxrs/main/module.xml to add dependencies on CXF modules so that JaxrsScanningProcessor can use CXF as JAX-RS stack as an alternative. To go with this approach, you will have to install CXF in AS 7 by yourself, then define cxf modules similar to what org/jboss/resteasy/resteasy-jaxrs/main/module.xml does. 2. Disable JaxrsScanningProcessor so that Guvnor can use CXF to load JAX-RS resources using CXF's own way. This approach is what we did in AS 6. We configured CXF to use its own non-standard way to load JAX-RS resources other than using the standard javax.ws.rs.core.Application. But for some unknown reasons, this approach seems not working for AS 7 anymore. I can take a further look once I have time.
