RE: [rules-users] Rules with Lookup Tables...
I also need to make a rule with a lookup tables, and I have found that the new
version of rules support 'from'.
The syntaxe it's something like:
'from'
* http://jira.jboss.com/jira/browse/JBRULES-341
'from' allows the engine to reason over data not inside the engine, this can be
used with global variables to interact with data providing services, such as
hibernate. MVEL provides the scripting language capabilities for this, any
previously bound variable can be used in the MVEL expression. The following
example shows a hibernate named query with some dummy properties that returns a
list of Restaurants. Restaurant() is a standard pattern, and can have its own
field constraint and bindings like any other pattern.
$r : Restaurant( $postCode ) from hbSession.getNamedQuery( "some query"
).setProperties( [ key1 : value2, key2 : value ] ).list()
I haven't tried it yet, and I have some questions also. But go ahead! :-)

I don't have the syntax at hand but Edson has previously posted about
using "from" in similar circumstances.
This would allow you to access a lookup table on a database as part of
the LHS of a rule.

Subject: [rules-users] Rules with Lookup Tables...
I need to evaluate a set of Rules with some of the operators comparing
values
from Facts against a changing Lookup Table - for instance:
Some Partners may have several lookup tables defined like this:
NISSAN has partner_ids = {, , , 6} and port_locations =
{ABC, EFG, GEE, FDD...} - these values are stored in the database and
need
to be evaluated at run-time.
I suppose one way I could do this is to write a rule like this (sorry,
syntax probably off a bit)...:
rule "partner and port match"
when
$shipment: Shipment(customerName== "NISSAN", partnerID== ""
|| customerName=="NISSAN",
partnerID==""
|| customerName=="NISSAN",
parternID=="")
|| customerName=="NISSAN",
portLocation=="ABC"
|| customerName=="NISSAN",
portLocation=="EFG"
|| customerName=="NISSAN",
partLocation=="FDD")
then
System.out.println("Found the right one!");
end
Trouble is that the values in these lookup tables change frequently, so
I
would like to create a rule that references a lookup table that does a
DB
lookup to evaluate the values at run-time - something like this:
rule "partner and port with lookup-table"
when
$shipment: Shipment(customerName== "NISSAN", partnerID in
$(partner_ids
) ) <-- db lookup here
|| customerName=="NISSAN", portLocation
in
$(port_locations)) <-- db lookup here
then
System.out.println("Found the right one!");
end
I know this is probably a stretch in this case - just wondering if
anyone
else was able to solve such a problem?! If so, how -
Thanks,
James

Hey there Barry, great to hear from you. It's still drools too :) all the R&D project stuff is "drools". anything that is released and supported is jboss rules. I'm using 3.2.1 and it's fine, you need to turn on the caching stuff in the preferences, it uses that for debugging. You also need to run it as a drools debug session, not a standard java one. So you'll need to go into the launcher configuration to create new drools debug sessions. We'll start docs once towards the end, when everything has stabalised.

[rules-users] Adding DROOLS/JBoss Rules to classpath WITH LINE NUMBERS
Hi everybody! I have added the JBoss rules - drools 3.0.5 to an existing eclipse project. I have already solved the problem of adding the source code of drools to the debugging of eclipse, using the first indication of Kris, witch is quoted in the end! Now the problem it's being able to debugging using the source of drools, but having the line number, so that eclipse can follow the exact actions of the source. Can anybody help me?! Yes, the drools jars do not contain any source by default (to limit the size of the jars). There are two ways to use the source of these classes though: * When you are trying to debug an application in eclipse, and you open the debug dialog (right click your Java main class, select Debug As -> Debug ...), there is a tab there you can use to add sources. If you download the sources from svn and import these as Java projects in eclipse, you can just add those projects to the source lookup path. I added a screenshot to help you out with that. * If you add the sources to the drools jars directly (in the same dir as the corresponding class files, so not in a separate src dir or something like that), those sources will be found automatically as well. So rebuilding those jars and adding the sources should do the trick for all your projects at once. Kris Thanks in advance for the attention of this problem. __ Francisco Brum - [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Link Consulting - http://www.link.pt/ <http://www.link.pt/> Tel.: 213 100 031 Av.

RE: [rules-users] rule chaining problem?
What you cold do it's before deleting a node, first you will remove it arcs! Maybe using a flag identifying future node to delete, and all the arcs from a node with that flag is deleted. And then delete the node. To do that, use the term salient. I'm just a beginner in rules, but this seams right. __ Francisco Brum - [EMAIL PROTECTED] Link Consulting - http://www.link.pt/ Tel.: 213 100 031 Av.

Hi everyone, I have this scenario: A diagram with nodes and arcs between them. I'm willing to control the visual elements with rules. Nodes are asserted at the moment of insertion. Object node = new AnyObject() ; FactHandle hNode = workingMemory.assertObject( node ) ; Nodes are retracted from working memory when are deleted from the diagram. workingMemory.retractObject( hNode ) ; Arcs can not exist in the diagram if any of the related nodes no longer exists. So I must have a rule that keeps consistency in the diagram, something like: ## to illustrate the problem just checking source rule "Delete no longer valid arcs" when a : Arc(s: source, tag, t: target) not s: Object() then retract(a) ; end But the rule is not working, help is much appreciated Regards, Gerardo Segura ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] java.lang.NoSuchMethodError
Hello everybody! I'm having the same problem that you had, but when I run the project from the JBoss Server and try do run the code with the JBoss rules, I get the error: java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem; at org.apache.commons.jci.compilers.EclipseJavaCompiler$2.acceptResult(EclipseJavaCompiler.java:237) at org.eclipse.jdt.internal.compiler.Compiler.handleInternalException(Compiler.java:415) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:352) at org.apache.commons.jci.compilers.EclipseJavaCompiler.compile(EclipseJavaCompiler.java:268) at org.drools.compiler.PackageBuilder.compileAll(Unknown Source) at org.drools.compiler.PackageBuilder.addPackage(Unknown Source) at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source) I've downloaded the ecj.jar, which haves the org\eclipse\jdt\internal\compiler\CompilationResult.class with the getProblems() method, to the \lib folder of the server! But it seems that this ecj.jar haves some conflict, because there are times that it works and others it doesn't. So I have tried do look for the org.eclipse.jdt.core_3.2.0.v_642.jar In my org.drools.ide_3.0.5, but didn't found it. Don't know where to!! What should I do? Thanks in advanced for your attention FBrum.

What I said still holds true though - make sure the v642 jar is at the top of your runtime classpath.
