[rules-users] Flow Timer causes exception: Caused by: java.util.concurrent.RejectedExecutionException
Hi, I have a flow and a set of rules. In the flow I have a wait state. If the wait state has a timer, when the flow reaches the node it blows up with the following exception ( See Below ), if I remove the timer everything works.

Re: [rules-users] Looking for a place to start with drools
Hi Dean, I ve only been working with Drools for about a couple of months. My first impression was that it was a great tool and very straightforward. But as I got deeper into it, I found a lot of gotchas, and things I didn't quite understand how they worked ( for many I still don't ). Finding definitive answers to those questions has been hard. Even though this forum, as well as the IRC chat are very helpful, the flow of information is somewhat limited. If what you are doing has some complexity beyond the simple examples provided by the documentation, and sample code, then you will probably get stuck at some point, and burn a lot of time trying to figure out the problem. So if you are on a tight budget that requires tight deadlines using Drools to replace your existing code would be a high risk proposition I believe. On the other hand, the Drools's potential to simplify, and streamline my system is great. if I manage to get it to do what I want it to do it would be a huge win for my organization, and the Drools system would be mostly responsible for that. So to summarise, jumping into the Drools bandwagon would be an "educated bet", but a bet nonetheless. Hope that helps.

[rules-users] On Entry On Exit actions question
Hi, When using an "Email" node for example, where On Entry, and On Exit actions are available. If I create an object within the On Entry action ( Let's say a list of recipients for the email ), how do I access that data from the body of the email ? What is the best strategy to access data that was created on the On Entry action, from the node itself ?

Re: [rules-users] How to remove a persisted session from the database ?
Yeah thanks ! I had figured it out, but how do you get your
"transactional context" ?
I ended up doing the following, in case someone else needs to do the same:
within a class...
public void deleteSession(StatefulKnowledgeSession session)
{
initTransactionManager();
this.txm.begin();
registerRollbackSync();
SessionInfo info =
jpm.getApplicationScopedEntityManager().find(org.drools.persistence.session.SessionInfo.class,
new Integer(session.getId()));
System.out.println("This is the sessionInfo: " + info);
jpm.getApplicationScopedEntityManager().remove(info);
jpm.getApplicationScopedEntityManager().flush();
this.txm.commit();
}
private void initTransactionManager() {
Object tm = environment.get(
EnvironmentName.TRANSACTION_MANAGER );
this.txm = new JtaTransactionManager( environment.get(
EnvironmentName.TRANSACTION ),
environment.get(
EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY ),
tm );
this.jpm = new DefaultJpaManager(this.environment);
}
private static class SynchronizationImpl
implements
TransactionSynchronization {
JPAKnowledgeSessionLookup service = getInstance();
public SynchronizationImpl(JPAKnowledgeSessionLookup service) {
this.service = service;
}
public void afterCompletion(int status) {
if ( status != TransactionManager.STATUS_COMMITTED ) {
this.service.rollback();
}
this.service.jpm.endCommandScopedEntityManager();
}
public void beforeCompletion() {
}
}
Thanks

[rules-users] How to remove a persisted session from the database ?
Hi,
I am using persistence, and since the sessions don't seem to have a
standard way of getting removed from the database when they are not
needed anymore, I am wondering how to do that.
I am using JPA but if I call :
em.remove(someSessionInfo);
where em is the JPA EntityManager, that does not remove the entry from
the database.
if I try to use a Query returned by the em.createQuery("delete from
SessionInfo where id = 1") it complains that it needs a transaction,
and since I don't know how to get around the issue I am stuck.
Any help would be appreciated.
Thanks

[rules-users] Invalid StatefulKnowledgeSession id returned
Hi, I am having an issue where after creating a new StatefulKnowledgeSession using JPA for persistence, the id returned by the getId() method on the session returns 0, even though I can see the session id in the database is not 0 but some other integer. There are no exceptions thrown. Does anyone know why this is? Thanks ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] How do sessions get removed from the database ?
Hi, I am using StatefulKnowledgeSession and JPA for persistence. I create a session for each Drools Flow process I start, so there is a 1 to 1 mapping between the session and the process. When the process ends, I can see the process gets removed from the database. How can the session be removed from the database as well ? Do I need to do that manually ?

[rules-users] Keeping track of sessions and their process instances
Hi,
I am working on a flow that uses flow events.
I send the event from a rule, and the only way I know to send an event
requires that I know the processId as well as the sessionId. Which
means I need to be able to keep track of both those two values so that
I can later use them to send the event.
So the question is what is the best strategy to keep track of the
sessions and the processes ?
The following is what I do; please comment on it, and feel free to
suggest a better way.
I ve created a class called WorkflowInfo that has two members (
processId, and sessionId )
When I start the process I create a WorkflowInfo, I set the processId,
and the sessionId then I insert it into the working memory:
WorkflowInfo info = new WorkflowInfo();
info.setProcessId(instance.getId());
info.setSessionId(ksession.getId());
ksession.insert(info);
In one of the rules I check for a condition, and when it is met I send
the flow event:
rule "sendEvent"
when
$info : WorkflowInfo()
then
DroolsEventsManager.getInstance().sendEvent($info.getProcessId(),
$info.getSessionId(), "someEvent");
end
Now to send the event this is what I do ( from a java class ):
public void sendEvent(long processId, int sessionId, String eventType)
{
StatefulKnowledgeSession session =
JPAKnowledgeSessionLookup.getInstance().loadSession(sessionId);
try {
SignalEventCommand command = new SignalEventCommand();
command.setProcessInstanceId(processId);
command.setEventType(eventType);
command.setEvent(true);
session.execute(command);
} catch (Exception e) {
Logger.getInstance().error(this.getClass(),
e.getMessage());
e.printStackTrace();
}
finally{
session.dispose();
}
}
Does this approach make sense ?
Thanks

Re: [rules-users] Drools Flow - Session objects
I don't totatlly understand the process / session lifecycle, and how the rules and the flow are related to one another in time. But I wanted to see if the following would work. See what happens if you create a flow that has the Start + your RuleFlow node + a Timer + End Set the timer to 6 or something like that. Then see if it works.

Re: [rules-users] Persistence.createEntityManagerFactory NullPointerException
If it helps at all; I spent almost a full week trying to get JPA to
work with Tomcat 5.5 + Hibernate + Bitronix and this is what I found.
The instructions for Bitronix in
http://docs.codehaus.org/display/BTM/Tomcat13 did not help me much.
The datasource that gets created via the resource.properties could
never be found.
- So to get it to work, do deploy the Bitronix jar files into your
server / context
- In the Tomcat conf/context.xml I do have "" but I
am not sure if it is required ( haven't tested removing it ).
- In the web.xml I do have:
java:comp/env/jdbc/processInstanceDS
javax.sql.DataSource
where jdbc/processInstanceDS is your jdbc/mysql
- In the Hibernate persistence.xml I do have:
although I don't think it is using the jndi.class specified there, so
the second line might be redundant.
Then in my code I create the datasource by hand ( in a ServletContextListener ):
PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName( "jdbc/processInstanceDS" );
ds.setClassName(
"bitronix.tm.resource.jdbc.lrc.LrcXADataSource");
ds.setMaxPoolSize( 3 );
ds.setAllowLocalTransactions( true );
ds.getDriverProperties().put("driverClassName","com.microsoft.sqlserver.jdbc.SQLServerDriver");
ds.getDriverProperties().put( "user", "xxx" );
ds.getDriverProperties().put( "password", "" );
ds.getDriverProperties().put( "url",
"mySqlServerUrl..." );
replace the driverClassName, user, password, and url for your setup. I
am using SQLServer, but I guess you are on MySql.
After that the JPA stuff works, and persistence works as advertised.
This is the only setup that worked for me. I tried creating the
datasource from Spring but that didn't work either.
Please let me know what you find out.
Thanks

[rules-users] Is transaction management required for Drools process / session persistence
Hi, I am trying to do Drools persistence in Tomcat with Hibernate, but it would seem it also requires transaction management. Is that true? In the meantime I tried to setup Bittronix to provide the transaction management, but I can't get Hibernate to find the datasource at all. I ve followed the BTM integration instructions for Tomcat, I ve also done followed the BTM integration instructions for Hibernate, but still nothing, Hibernate keeps saying it can't find the datasource. Can anyone shed some light on this ? BTW: my database is SQL Server Thanks ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Where is MinaTaskClient ?
Hi, I am trying to connect to the mina server using the MinaTaskClient referred in the documentation; however the class does not seem to exist. I got the latest Drools 5.1 download. In any case how can I connect to the server in order to retrieve the tasks ? I see the TaskClient has the methods I need, but I am not sure how to create one, and everything I ve tried fails to retrieve a working TaskClient. I appreciate your help.
