Hi I am having the following problem: I am able to start the web cosole successfully and see all the process List that I want to execute.

[rules-users] [Urgent] Error in ontext assist in DSLR Editor
Hi All,
I have been using drools 4 for couple of months now and I am starting to get
the hang of it. We recently decided to move to Dools 5 with Eclipse 3.4.2
(Ganymede).
We unfortunately hit a major 'show stopper' (for us). In the DSLR editor:
Context Assist + space + enter removes/replaces the whole line, not only the
place holder.
In other words:
DSL:
[*][]Log : {msg}=System.out.println({msg});
[*][]id1=some id label
DSLR:
rule MyRule
when
then
end
If I Press L , control space -- the line Log:{msg} appears in the context
menu. Hit enter I get
Log :{msg}
Now, If want to replace msg by id1. I position the cursor in the {msg}, hit
ctrl space, id1 shows in the list. I hit enter the whole line disappear, and
I am left with
id1
instead of
Log : id1
Is this a setting somewhere in eclipse itself?? I doubt it.
The same thing use to work as expected in Drools 4.
thanks.

Re: [rules-users] Working in the GWT console
Does your test case work if you run it from Eclipse directly (for example using a knowledge agent to load them from guvnor or simply loading from file system) and using the Eclipse task client (to eliminate the possibility that there is something wrong with the process)? Might be useful if you could show us the process itself as well.

Re: [rules-users] Drools Flow :Persistence Problem : Restore StatefulKnowledgeSession from database
Preferably you should cache the session itself as well (so you don't have to recreate it all the time) and reuse that across you application. Or you could have multiple independent sessions as well. If you store the key of the session somewhere, you can easily restore this session (or sessions) after failure.

Am I right ? So when I try to finish the 1st workflow by executing the 2nd humantask left in it , I need to reload the StatfulKnowledgeSession object from the database. As there is no way of distinguishing that the session object store in the database is of which workflow , there might be a problem as I may get the ksession object of 2nd workflow. In case of Process Instance it is fine , because there is a field 'processId' which will distinguish which processInstanceId belongs to which worklowId or processId.

Re: [rules-users] Working in the GWT console
Hi Kris
I am new to Drools. I didn't perform a test case from eclipse by using a
knowledge agent to load them from guvnor. Well I have a question after I
build the application on Guvnor should I do something like copythe .pkg to a
specific location or just restart the server and Launch the GWT console.
What I did is the following:
1- I uploaded a jar file of my process into Guvnor below is the sample java
file that i am using:
package com.fp;
import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderError;
import org.drools.builder.KnowledgeBuilderErrors;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.logger.KnowledgeRuntimeLogger;
import org.drools.logger.KnowledgeRuntimeLoggerFactory;
import org.drools.process.instance.impl.demo.SystemOutWorkItemHandler;
import org.drools.process.workitem.wsht.WSHumanTaskHandler;
import org.drools.runtime.StatefulKnowledgeSession;
public class TestDrools
{
public static final void main(String[] args)
{
try
{
System.out.println(\n\n\n i am here );
KnowledgeBase kbase = readKnowledgeBase();
// // create the entity manager factory and register it in
the environment
// EntityManagerFactory emf =
// Persistence.createEntityManagerFactory(
org.drools.persistence.jpa );
// Environment env = KnowledgeBaseFactory.newEnvironment();
// env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
// env.set( EnvironmentName.TRANSACTION_MANAGER,
//
TransactionManagerServices.getTransactionManager() );
//
// // create a new knowledge session that uses JPA to
store the runtime
state
// StatefulKnowledgeSession ksession =
// JPAKnowledgeService.newStatefulKnowledgeSession(
kbase, null, env
);
final StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
// start the transaction
// UserTransaction ut =
//(UserTransaction) new InitialContext().lookup(
java:comp/UserTransaction );
// ut.begin();
KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, test);
ksession.getWorkItemManager().registerWorkItemHandler(Human Task, new
WSHumanTaskHandler());
ksession.getWorkItemManager().registerWorkItemHandler(Log, new
SystemOutWorkItemHandler());
// perform multiple commands inside one transaction
ksession.startProcess(testDroolsFlow);
//ksession.fireAllRules();
// commit the transaction
// ut.commit();
} catch (Throwable t)
{
t.printStackTrace();
}
}
private static KnowledgeBase readKnowledgeBase() throws Exception
{
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(testDroolsFlow.rf),
ResourceType.DRF);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() 0)
{
for (KnowledgeBuilderError error: errors)
{
System.err.println(error);
}
throw new IllegalArgumentException(Could not parse
knowledge.);
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
}
}
2- uploading the process rule flow below is the .rf file that i am using:
?xml version=1.0 encoding=UTF-8?
process xmlns=http://drools.org/drools-5.0/process;
xmlns:xs=http://www.w3.org/2001/XMLSchema-instance;

humanTask id=4 name=Task1 x=95 y=184 width=100 height=48
work name=Human Task
Re: [rules-users] Working in the GWT console
Kris I also found the following issue if the USER TASK 1 and USER TASK 2 are
assigned to the same user I can see both tasks and execute them but if for
example Task 1 is assigned to admin and Task 2 is assigned to admin1 after
logging out and logging in as admin1 I cant see that the tasks that are
assigned to him in order to complete the process. Another issue if I have
another scenario a User Task Followed by LOG for example The User task is
executed but the process that is following it which is a LOG in our example
is never reached or executed.
PS. for the LOG process I defined a special handler for it which only
contanins System,out,
public class MyLogHandlerCall implements WorkItemHandler
{
public void executeWorkItem(WorkItem workItem, WorkItemManager manager)
{
try
{
System.out.println(R TEST);
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void abortWorkItem(WorkItem workItem, WorkItemManager manager)
{
System.out.println((new StringBuilder()).append(Aborting work item
).append(workItem).toString());
manager.abortWorkItem(workItem.getId());
}
}
Please advise!

[rules-users] Stateful session and non-existence of Facts
Hi Guys, I have the following situation while running a stateful session with Drools 4.0.7: - I want to test that a fact with a given state doesn't exist; - It works fine - At a certain point I have to retract all facts and reinsert them at the stateful session - some of them actually changed and I don't want to recreate the session b/c it's expensive - Again the fact that didn't exist when I first created the session still doesn't exist ** Problem: This time the rule that verified the non-existence is not fired because I didn't insert any fact that would retrigger it. Rule example: rule 022 when SiteLanguage(language : languageCode) t : SiteSpecialServiceType(type : specialServiceType) not SiteLanguageSpecialServiceType(specialServiceType == type, languageCode == language) then consequence end How could I solve or workaround that?

Hi Geoffrey,
I have modified the LocalSearchSolverConfig class to accept the scoreDsl tag.

Am I right ? So when I try to finish the 1st workflow by executing the 2nd humantask left in it , I need to reload the StatfulKnowledgeSession object from the database. As there is no way of distinguishing that the session object store in the database is of which workflow , there might be a problem as I may get the ksession object of 2nd workflow. In case of Process Instance it is fine , because there is a field 'processId' which will distinguish which processInstanceId belongs to which worklowId or processId. But in case of Session , there is noting as such. I don't what I am saying is handled in drools persistence. Please let me know if it there or not.

Re: [rules-users] Stateful session and non-existence of Facts
Leonardo, First, I believer there is a misconception in your reasoning: creating sessions is supposed to be much much cheaper than retracting all facts. Creating a rulebase is heavier, because it requires compilation, but creating a session is supposed to be very light by design. So, first thing you should do is change that. Regarding your question, if you insert: SiteLanguage(language : languageCode) t : SiteSpecialServiceType(type : specialServiceType) The rule will activate and fire. If you don't, then the rule will not match. That is how it is supposed to work. Edson 2009/11/17 Leonardo Gomes leonardo.f.go...@gmail.com Hi Guys, I have the following situation while running a stateful session with Drools 4.0.7: - I want to test that a fact with a given state doesn't exist; - It works fine - At a certain point I have to retract all facts and reinsert them at the stateful session - some of them actually changed and I don't want to recreate the session b/c it's expensive - Again the fact that didn't exist when I first created the session still doesn't exist ** Problem: This time the rule that verified the non-existence is not fired because I didn't insert any fact that would retrigger it. Rule example: rule 022 when SiteLanguage(language : languageCode) t : SiteSpecialServiceType(type : specialServiceType) not SiteLanguageSpecialServiceType(specialServiceType == type, languageCode == language) then consequence end How could I solve or workaround that?

[rules-users] Getting java.util.ConcurrentModificationException when updating a fact from Decision Tables.
I have a decision table with one CONDITION column. My fact could match
multiple rules (rows) of the decision table. With each match, the
'ACTION' cause the fact itself to change. I'm using 'modify' as follows
to change my fact:
modify ($line) { addItem( new Item(DISCOUNT,25%)); }
(essentially I need to add a item to a line when ever the LHS matches).
This works fine when I use a DRL. But when I try to use a decsion table,
I get 'java.util.ConcurrentModificationException' the second time my
fact matches a rule.
Does anyone know if we can modify facts from decision tables ? All the
examples I've seen so far don't show how decision tables handle updating
of facts.
Here's the stack trace I get :

Re: [rules-users] Need Syntax help for a string match
The rete view for the following two rules have identical structure: (One alpha node in each) rule Test when t : Thing( foo == BAR || == BAS ); then System.out.println( meh ); end rule Test when t : Thing( foo in(BAR,BAS) ); then System.out.println( meh ); end So I guess the || == conditions are combined into one node. I can't peek into the source at the moment to check, though. And I don't know which is faster. I'd guess that either is faster than regex for short lists, though. --- On Tue, 11/17/09, Mauricio Salatino sala...@gmail.com wrote: From: Mauricio Salatino sala...@gmail.com Subject: Re: [rules-users] Need Syntax help for a string match To: Rules Users List rules-users@lists.jboss.org Date: Tuesday, November 17, 2009, 3:31 PM @Greg Using in is better that the multiple || == 18 ?

I need to compare date from java bean to system date for a rule. I referred
to previous posts, drools expert documentation and tried to come up with a
rule which is not yet working. Please help me for the same.
1. Which package should i import to use DateFactory? It is not in
org.drools.base.evaluators.DateFactory anymore i guess. Is there a better
way to get CurrentSystemDate other than using DateFactory?
2. In my JavaBean the date has format dd/MM/. So where do i set this
format to drools.dateformat? In my .drl file or in the java pgm where i load
the .drl file and do insertion of fact objects and fire the rules.
rule SetTktIssueDate
when
DateFactory($sysdate : today )
$br:BillingRecord(tktIssueDate==null || tktIssueDate sysdate)
then
modify($br){setTktIssueDate(sysdate);}

Re: [rules-users] Drools Flow :Persistence Problem : Restore StatefulKnowledgeSession from database
Hi Kris, Thanks for you valuable input and Vijay of course clearing some of my doubts by asking question on this. Much of my doubt are clear except one. When we are reloading the StatefulKnowledgeSession from the database using the below line StatefulKnowledgeSession loadSession= JPAKnowledgeService. loadStatefulKnowledgeSession(id, kbase, null, env); This session object is different from the one that is created when we first created StatefulknowledgeSession object using StatefulKnowledgeSession initialSession= JPAKnowledgeService. newStatefulKnowledgeSession(kbase, null, env); Am I right ? Now In my case I have a HumanWorkItemHandler class for handling the humantask and there is ActionWorkITemHandler for my customAction workItem, which both are initailsed with the initialSession object. Now when I load the session from the database to complete the HumanWorkItemHandler task I got a different session object i.e. loadSession. Now when I insert something in the loadsession using loadSession.insert(request); So that I can use the same in ActionWorkItemHandler to exceute the action for the request. I am not able to retrieve the same request object i.e. (HttpServletRequest) from the session in ActionWorkItemHandler as when i do Collection obj = loadSession.getObject(); I get request as null. Because this loadSession is different from the one I have inserted. Kindly help in this, or I have misunderstood the concept.

The session in this case is a global session, meaning that it will be used for all process instances. Note however that, unless you are using timers, all other state (process instance state, work items, etc.) is persisted separately and the session state will basically be empty. It is also possible to have one session per process instance (or whatever partitioning you like). A session has a unique id (which you can specify when reloading the session). You'll then have to load the right session before continuing the execution of your process instance. Kris Quoting pardeep.ru...@lntinfotech.com: Hi Salaboy, Thanks for you replying. Yes, of course it is storing multiple process instance Id in the database. But, what I feel is that it will fail when I am trying to run two workflow at the same time simultaneously, using the same code by dynamically providing the workflow name and the parameters for each of them. Ideally there should be two entries for the StatfulKnowledgeSession object because when I try to load the StatefulKnowledgeSession object from the database it will give me the session object of the workflow which is last executed. For example lets suppose I have two workflow 1 and 2 having two humantask in each of them . So when I finish the first Human Task of both workflow one by one. SessionInfo present in the database is of workflow 2 (if 2 is executed last). Because there is no field in the sessioninfo entity of the database regarding to which workflow it belongs to.
