5.0.0.M5 and looked at the test cases but I guess I'm still not quite
getting it, so I'm hoping someone here can point me in the right

I've got an XML file defined basically like this:

Within the XML file, there is 1 and only 1 "facility" node and
multiple "lineitem" nodes. I'd like to use the DroolsSmooks pipleline
functionality to use Smooks to insert 1 "facility" fact and multiple
"lineitem" facts into my knowledgbase.
The code I've written to do this is similar to the following (taken
from sample test code I've seen in the Drools source):
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
Action executeResultHandler = PipelineFactory.newExecuteResultHandler();
KnowledgeRuntimeCommand insertStage =
PipelineFactory.newStatefulKnowledgeSessionInsert();
insertStage.setReceiver(executeResultHandler);
Smooks smooks = new Smooks("smooks-config.xml");
Transformer transformer =
PipelineFactory.newSmooksFromSourceTransformer(smooks, "root");
transformer.setReceiver(insertStage);
Pipeline pipeline =
PipelineFactory.newStatefulKnowledgeSessionPipeline(ksession);
pipeline.setReceiver(transformer);
ResultHandlerImpl resultHandler = new ResultHandlerImpl();
pipeline.insert(ResourceFactory.newClassPathResource("submission.xml"),
resultHandler );
While stepping through the above code, the last line returns an NPE.
I've tried playing with the "Transformer transformer -
PipeLineFactory..." line, substituting "root" for something else and
it goes into an infinite loop. What is the purpose of the "root" value
being set in this line?
Can anyone tell me if I'm even on the right track here, or am I
misunderstanding what the Smooks data loader can do for me?

Hi Kris,
Hummm... Its true, after all Workitem stills been a java class with
gets and sets... ;-)

Cristiano,
If the working memory is always different per work item, you could
use a global and pass it as a parameter of the work item.
However, in general it does seem better to set this on the work item
handler directly at construction time, as a parameter on your work
item handler. Something like this:
StatefulKnowledgeSession session = ...
MyWorkItemHandler myWorkItemHandler = new MyWorkItemHandler();
session.getWorkItemManager().registerWorkItemHandler("...",
myWorkItemHandler);
myWorkItemHandler.setSession(session);
If you have more than one possible session, you could inject a
session locator instead of the session itself to locate the session
at runtime.

Hi people,
Im trying to create a workitemhandler for use Drools Pipeline and
Smooks to import data inside working memory and process it.
I want to share the working memory that was created for the main

What is the best approach to do that, use Globals to pass the

any ideias?

Re: [rules-users] Creating objects in WHEN clause
Well, since the StatelessSession is basically a convenience wrapper around a
StatefulSession I figure it should be possible. On StatefulSession, which
extends WorkingMemory, you just call setFocus() before firing the rules. I'm
not sure what the best way to do this with a StatelessSession would be. I can
think of some hacks, but would rather not lead you down a garden path. :) Dev
d00ds, any comment?

Re: [rules-users] Help on using Drools with embedded objects
You've answered your own question. The method is non-static. You must call it
on a particular instance. You can pass the instance in as a global variable or
match on it in the rule.
global com.test.serviceImpl.StaffingFormMailingServiceImpl foo;
or
when
$s:StaffingForm(...)
$f:StaffingFormMailingServiceImpl()
then
...
end
Unless you have multiple StaffingFormMailingServiceImpl instances, the first
option is best.

Re: [rules-users] Timer isn't firing
Cristiano, There are some examples on processes using timers here: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler/src/test/java/org/drools/integrationtests/ProcessTimerTest.java If you need help, could you maybe send me the test project you are trying to execute, so I can take a look? Kris - Original Message - From: Cristiano Gavião To: Rules Users List Sent: Monday, March 02, 2009 2:34 AM Subject: [rules-users] Timer isn't firing Hi, I've created a simple process flow with a start node followed by a timer (with delay = 1 and period = 0), an workitem node, and an end node. Its simple but isn't working properly. The problem is that process isn't getting out from the timer node. Nothing happens... Its something more needed to get timer working? This is the output generated: BEFORE RULEFLOW STARTED process:ProcessoX[id=ProcessoX] BEFORE RULEFLOW NODE TRIGGERED node:Start[id=20] process:ProcessoX[id=ProcessoX] null process:ProcessoX[id=ProcessoX] BEFORE RULEFLOW NODE TRIGGERED node:Timer[id=19] process:ProcessoX[id=ProcessoX] AFTER RULEFLOW NODE TRIGGERED node:Timer[id=19] process:ProcessoX[id=ProcessoX] null process:ProcessoX[id=ProcessoX] AFTER RULEFLOW NODE TRIGGERED node:Start[id=20] process:ProcessoX[id=ProcessoX] AFTER RULEFLOW STARTED process:ProcessoX[id=ProcessoX] thanks in advance _ Cristiano V.

Re: [rules-users] Ksession inside a executeWorkitem() ?
Cristiano,
If the working memory is always different per work item, you could use a
global and pass it as a parameter of the work item.
However, in general it does seem better to set this on the work item handler
directly at construction time, as a parameter on your work item handler.
Something like this:
StatefulKnowledgeSession session = ...
MyWorkItemHandler myWorkItemHandler = new MyWorkItemHandler();
session.getWorkItemManager().registerWorkItemHandler("...",
myWorkItemHandler);
myWorkItemHandler.setSession(session);
If you have more than one possible session, you could inject a session
locator instead of the session itself to locate the session at runtime.

Subject: [rules-users] Ksession inside a executeWorkitem() ?
Hi people,
Im trying to create a workitemhandler for use Drools Pipeline and Smooks
to import data inside working memory and process it.
I want to share the working memory that was created for the main process
that is calling the workitem for configure the Drools Pipeline inside it.
What is the best approach to do that, use Globals to pass the
knowledgesession?
any ideias?
Thanks in advance

Re: [rules-users] Drools Flow Trigger process by ruleset
Garrett, The 3rd option you describe is currently possible in the core engine, however support has not yet been added to the graphical designer for this. You can however manually add it in the XML directly for now. If you look at the XSD it should look something like this: p:Person() As you can see you can also specify additional parameters (that are passed in as variables to the process instance), either by relating them to a parameter of the rule or by specifying an explicit value. Note that it is internally simply translated to your 2nd option. We'll try to add the editor for this property for the Drools.5.0.0.GA release.

Re: [rules-users] Help on using Drools with embedded objects
I have still not found a solution to the problem.
The problem is that I have a non static function in my service class and i
have to call thhat from my drools rule file.
The function basically accepts a mail id and if a mailing list returns an
arraylist of the individual mail ids in the mailing list.
my drl file looks like this:
package com.test.ams.rule
dialect "java"
import java.util.ArrayList;
import org.json.JSONArray;
import java.net.HttpURLConnection;
import java.net.URL;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import com.test.domobjects.StaffingForm;
import com.test.domobjects.StaffingFormOfferDetails;
import com.test.domobjects.OfferResponseType;
import function
com.test.serviceImpl.StaffingFormMailingServiceImpl.expandTheMailingList;
global java.util.HashMap myOSFRecipientsMap;
rule "Part A"
salience 20
no-loop true
when
$s:StaffingForm(staffingFormOfferDetails.offerValue== true &&
staffingFormOfferDetails.offerResponseType.offerResponseTypeName ==
"Accepted")
then
$s.setPartARecipients((ArrayList)expandTheMailingList((String)myOSFRecipientsMap.get("PART_A_EXEC_COMMITTEE")));
$s.setPartARecipients((String)myOSFRecipientsMap.get("PART_A_CONFIDENTIAL"));
$s.setPartARecipients((String)myOSFRecipientsMap.get("PART_A_PAYROLL"));
update($s);
end
This gives me an exception -- java.lang.RuntimeException: Unable to compile
"the.drl".
Please let me know what is the problem here.
Thanks
