Re: [rules-users] [Drools Flow 5.1] Updating a process definition -> Proceed updates running processes
Well the documentation sounds clear to me. The running process instances will continue running with the old version of the process and the new ones will pick the last uploaded version.

Re: [rules-users] Distributed Knowledge Base
Totally, that one of the ideas and it's currently supported. Drools grid allows you to create different execution nodes that can be located in different virtual/physic machine and then dynamically create sessions inside of them using a very similar API. The main idea right now in grid is to abstract the location where the ksession is actually running. Drools grid current implementation also provides a white pages service that allows you to register sessions by name. That will allow you to query the grid for a particular session, and the grid will return you a remote handler to the remotely hosted session.

Count me in, that's exactly what we want to achieve with the emergency service application in the long term, we are miles away from that goals, but one of the next steps is trying to automatically drive ambulances and add natural disasters to the situation.

I prefer the repository approach. Where the repository knows where to store our business assets and meta data. Right now guvnor is using jcr that can also be clustered.

About the out-mapping attribute, you are right this will copy the values from

Why are you doing that if you have the human tasks Apis to complete a task that

Re: [rules-users] Time to Scale some Drools
There will be some differences based on the underlying implementations that you choose. Drools grid will be just a common way to use those technologies. Right now I'm focused in hosting/access (using diferent transports) not in caching, but this could be easily added. About gridgain, I'm willing to test their drools integration and provide that solution integrated with grid too. As far as I saw, gridgain it's a map reduce solution, so I'm looking forward to some ode running using it.

Hi man, I'm working on drool-grid exactly for those scenarios I will be committing a new version next week, and it will be really nice if you can take a look on it. After my commit next week I will include more advanced technics to caching kbases on a distributed environments. Can you share your sla requirements that you have? So I can stress the current implementation.

Re: [rules-users] Drools 5 setGlobal
Well, in the second code snippet you are trying to set an unexistent
variable called test2. For setting a global variable you need to
define it first in the drl file. Greetings!

Re: [rules-users] data manipulation
For data manipulation you can use something like apache camel. To transform the information and then make inferences over it.

1) yes 2) no drools was disigned to handle a lot of rules, that's why rules templates exist 3) yes if you have a situation where your rules can be generated using a template. - Ing.

Re: [rules-users] Drools Road Map ????????????
I think that the decision is done by the project leader plus all the community members that are ending new features (usually not estimatable work/innovative), closing bug (non trivial ones), etc. In a big project like drools it's very difficult to set up deadlines and coordinate deliverables with this high grade of innovation. In my perspective(from the community side) this is not the best way to do it, but it give us innovation. - Ing.

Re: [rules-users] possible bug in latest SNAPSHOT - AccumulateFunction.init() is called when calling modify()
Could be that the modify make the rule condition to be no longer true,
and for that reason the acumulation is zero in that point? I would
like to try it but I'm in my cell phone.

You need to move the rules inside /src/main/resources/ and maven will

Re: [rules-users] Resuming Flow: NPE when completing a work item
Good to know that, can you share with us the types of the parameter
mappings, because this mappings get persisted to a binary snapshot in
the db. For this reason all the stuff that you put in there needs to
be serializable.
I'm implementing the same mechanism used by variable persistence
strategies to those mappings in work items parameters.

With a simple test case of the problem we can figured out the solution
of it's a problem or fix it if it's a bug. In both situations we will

Re: [rules-users] Resuming the Flow: SESSION_ID, PROCESS_INSTANCE_ID, WORKITEM_ID
Yes state is there. For your implementation you can create the high level API that you want, there's no problem with that right? I see that we discuss about what the framework should do or not based on different perspectives. We can continue forever if you do not switch your perspective. The code is there and it allows you to build applications applying the mechanisms that work better for you. For what I know there is no plan to create an API like the one you mention. (honestly I don't think it worth it, from the project perspective) Everything else that I can offer are suggestions to do a real implentation, but that will requiere as I mention before, knowledge about your particular domain. - Ing.

Here's another idea to bounce off of you: Given

What do you think?

Yes, of course, I add the VPS feature into drools so, I'm glad to

interested in do some contributions with JCR will be nice too!
Thanks a lot for your contributions!

Excellent, I have attached a unit test that demonstrates a query
made possible by the first patch, in case you are interested. The
unit test is designed to run in your example DroolsFlowVPS project,
since StringVariablePersister is not part of drools-persistence-
jpa. (Could StringVariablePersister be contributed to drools?)
2010/2/18 Mauricio Salatino
The first patch is already in the trunk.
About the second problem, we are trying to remove the
@CollectionOfElements annotation, (because it's hibernate specific)
that's why you see the other one commented out. I will try fix it
asap, to be able to use toplink as persistence provider as well.
Probably that will fix your problem too.
2010/2/18 Dale Wyttenbach
That's correct, it works fine using h2. Thanks.

Let me take a look at that too.. probably it's an oracle problem
right? I mean, probably it just happen with oracle.. we can create a
fix for that too
2010/2/18 Dale Wyttenbach
My pleasure.
Within ProcessInstanceInfo, I've got a similar observation about the
eventTypes member. 'private Set' is currently commented
out in favor of 'private Set'. When using an Oracle
hibernate dialect, this results in the DDL 'create table
ProcessInstanceInfo_eventTypes' which yields the error 'ORA-00972:
identifier is too long'. I imagine this will be resolved when the
String is promoted to EventType but I thought you might want to know.
2010/2/13 Mauricio Salatino
done.. I will apply the patch into the trunk.. it seems to be correct.
Thanks a lot!

I just want to make sure before apply the patch that the change will
not impact in other places.

If you try to write a query that requires
VariableInstanceInfo.processId, it won't work because that class has
no processId member.
I guessed that processInstanceId would be a better join column, and
that worked (patch attached)
Thanks for the reply.

Hmm..
I'm looking at the source and I see the following mapping:
@OneToMany(cascade = CascadeType.ALL)
@JoinColumn(name = "processId")
@MapKey(name = "name")
private Map variables =
new HashMap();
That makes me think that there is a join column called processId
between VariableInstanceInfo and ProcessInstanceInfo.

I have a patch for drools-persistence-jpa should anyone agree with
me that ProcessInstanceInfo and VariableInstanceInfo should be

Subject: [rules-users] Stumped by error in rule
After all this time working with Drools 5.0.1, I thought I’d figured
out all the ways my syntax could fail, but this one has me stumped.
Any help would be appreciated.
I have the following rule:
rule "RS6051.1.2_"
dialect "mvel"
when
Applicant ( $ApplicantNumber : ApplicantNumber )
not ( ScoreCard (name == "Context test", contextId
== $ApplicantNumber) )
then
ScoreCard scoreCard = functions.getScoreCardManager
().newScoreCard();
scoreCard.setName("Context test");
scoreCard.setContextId($ApplicantNumber);
insert(scoreCard);
end
I’m getting the following error on this rule during compilation:
Unable to create Field Extractor for 'ApplicantNumber' : [Rule
name='RS6051.1.2_']
org.drools.RuntimeDroolsException: Field/method 'ApplicantNumber'
not found for class
'com.wellsfargo.service.provider.sse.decisioning.x2009.
Applicant'Unable to build expression for 'consequence': null '
And here is (part of) the Applicant class in question:
package com.wellsfargo.service.provider.sse.decisioning.x2009;
public class Applicant
{
public Short getApplicantNumber()
{
return applicantNumber ;
}
public void setApplicantNumber(Short applicantNumber)
{
this.applicantNumber = applicantNumber;
}
Short applicantNumber;
}
And This is (part of) the ScoreCard class:
public class ScoreCard
{
public void setName(String name) { this.name = name; }
public String getName() { return name; }
public int getContextId(){return contextId;}
public void setContextId(int id){contextId = id;}
private String name;
private int contextId;
}
Why am I getting this error?
Help!

Re: [rules-users] Infinite loop when re-activating rules
Hi, you can add an extra restriction in C. That checks that the rules
property is empty in the first rule, the second, the third, the fourth
and the fifth will check the opposite. But the fifth rule will empty
again the rules property making the first rule fire again. I think
that you don't need lock on active or no loop with that.

Re: [rules-users] Call class method from LHS of a rule
This doesn't work because it not reference anything inside the eval, remember that inside the eval you must write an expression that will be compiled and evaluated in runtime. - Ing.

Re: [rules-users] Human Task Question on Mina client / server
You need to start the Mina server before starting the process

I am creating a human task in a flow, but I am unable to get the
human task in the Mina client. Should items that enter a
humanTaskNode go into the task table in addition to the workItemInfo
table? Do I need to do anything to get the work item set as a
potential owner for Administrator so it is returned to the Mina
client?
I running drools 5.0.1 in JBoss:
1. Create the human task node in the flow:
addActionStep(factory, 3).joinNode(4).type(Join.TYPE_XOR).done
().humanTaskNode(5)
.name("Approve")
.actorId("Administrator")
.taskName("Approve")
.comment("hi")
.content("random content")
2. Start the flow process (after this step I a row in the
workItemInfo table):
StatefulKnowledgeSession ksession = km.getSession(kb);
WSHumanTaskHandler approveTask = new WSHumanTaskHandler();
/* Setup workitemmanager here? */
org.drools.runtime.process.WorkItemManager wm =
ksession.getWorkItemManager();
wm.registerWorkItemHandler("Approve", approveTask);
ksession.setGlobal("entity", e);
ksession.startProcess(DuckFlowBuilder.PROCESS_NAME);
return ksession;
See the following in the log after this step:

3. Start the mina server (don’t see anything in the task tabl
e)
EntityManagerFactory emf = Persistence.createEntityManagerFactory
("org.drools.task");
taskService = new TaskService
(emf,SystemEventListenerFactory.getSystemEventListener())
server = new MinaTaskServer( taskService );
Thread thread = new Thread( server );
thread.start();
Thread.sleep( 500 );
System.out.println("Server started ...");
4. Run the mina client (no results returned)
BlockingTaskSummaryResponseHandler summaryHandler =
new BlockingTaskSummaryResponseHandler()
client.getTasksAssignedAsPotentialOwner("Administrator",
"en-UK",summaryHandler);
List tasks = summaryHandler.getResults();

Re: [rules-users] Drools Flow :Persistence Problem : Restore StatefulKnowledgeSession from database
No, of course that it can store multiple processes at the same time? Why you Say that looking at the tAbles looks like that! ? - Ing.

Will the drool-persistence will work for two or more workflow running simultaneously ? Also these workflow will use the same schema for all the workflows. Looking from the table that are generated in the database, it seems that database design is done keeping only one workflow running at a time. Am I thinking correct ?

Re: [rules-users] User interaction while ruleflow is running
the solution provided by Drools implements the WSHT standard, the idea is to decoulple the service from your application. The only difference with a built in solution that run thight coupled inside drools is that you only need to start it. Of course that you can automate that, so when your standalone application start, the human task server start too. You can also write your own Human task module and plug it inside Drools Flow if you want. On Thu, Sep 24, 2009 at 6:24 AM, Olaf Raether wrote: > > i suspect, that i get this answer.
