[rules-users] BaseMinaClient - Session Termination
Hello,
I have a simple RuleFlow containing a Human Task, which I start using the
following lines of code:
WSHumanTaskHandler wsh = new WSHumanTaskHandler();
ksession.getWorkItemManager().registerWorkItemHandler(Human Task, wsh);
ksession.startProcess(com.sample.ruleflow);
When the workflow has properly ended however, there remain threads (e.g.
NioProcessorNioSocketConnector) within the VM. I have tracked this down to
BaseMinaClient:
public void disconnect() {
if ( session!= null session.isConnected() ) {
session.close();
session.getCloseFuture().join();
}
}
Expllicitly calling wsh.dispose(), session.isConnected() (from IoSession)
always yields true even when the workflow instance has terminated already
and there are no more active human tasks available.
Is this an intended behaviour?
Thanks and best
Markus

[rules-users] Drool Rule Error with or not condition
Hi All,
I have the following drool rule that has or not under Entity Block.
Basically, the rule tries to check if there either exists an entity object
EtsExecutionOrderXref_core00 with the given conditions, or the entity does not
exist at all with some other conditions.
dialect mvel
rule Legacy ETSDB Rule
when
EtsExecutionOrderHist_core0:EtsExecutionOrderHist_core(customerOrFirm != 0)
EtsExecutionOrderXref_core00:
(
EtsExecutionOrderXref_core
(
entityOID == EtsExecutionOrderHist_core0.entityOID , entityRID ==
EtsExecutionOrderHist_core0.entityRID , entityVID ==
EtsExecutionOrderHist_core0.entityVID , referenceID != 2 referenceIDType
== orderSubCapacity
)
or not(EtsExecutionOrderXref_core
(
entityOID == EtsExecutionOrderHist_core0.entityOID , entityRID ==
EtsExecutionOrderHist_core0.entityRID , entityVID ==
EtsExecutionOrderHist_core0.entityVID , referenceIDType == orderSubCapacity
))
)
then
end
But, while compiling the rule, I am getting the following errors:
org.drools.compiler.DroolsParserException: [ERR 101] Line 22:16 no viable
alternative at input 'entityOID' in rule Legacy ETSDB Rule in pattern not,
org.drools.compiler.DroolsParserException: [ERR 102] Line 22:68 mismatched

input ',' expecting '(' in rule Legacy ETSDB Rule in pattern
EtsExecutionOrderHist_core0.entityOID in pattern
EtsExecutionOrderHist_core0.entityRID in pattern
EtsExecutionOrderHist_core0.entityVID]
I think the rule is correct, but am not able to figure out these compilation
errors. Could anybody please comment on why this would happen?
Thanks
Malay Shah

Re: [rules-users] Drool Rule Error with or not condition
You are binding the result of the 'or' to EtsExecutionOrderXref_core00
as the second part is a 'not' which returns nothing, how would it be
bound to?

Re: [rules-users] Drool Rule Error with or not condition
Thanks Mark. I removed the binding and the rule is compiled now, but while
firing the rule over set of objects, I get a Null pointer exception.
Here is the updated Drool rule:
dialect mvel

entityRID == EtsExecutionOrderHist_core0.entityRID,
entityVID == EtsExecutionOrderHist_core0.entityVID,
referenceID != 2 referenceIDType == orderSubCapacity
)
or
not(EtsExecutionOrderXref_core
(
entityOID == EtsExecutionOrderHist_core0.entityOID,
entityRID == EtsExecutionOrderHist_core0.entityRID,
entityVID == EtsExecutionOrderHist_core0.entityVID,
referenceIDType == orderSubCapacity

)
then
System.out.println(Rule fired);
end
and here is the stack trace:

After debugging through, DroolMVELFactory class object is looking for
Declaration definition for EtsExecutionOrderXref_core00, not finding it, and
hence giving a null pointer exception. I am using Drools 5.0.1. Any idea about
why this would happen? Does the rule seem right now?
Thanks

Re: [rules-users] Drool Rule Error with or not condition
Binding a variable to a fact in a branch of an 'or' (as you are doing with EtsExecutionOrderXref_core00) is not useful, since you cannot use this binding in the consequence. (The rule might just as well fire due to the 2nd term (the or not...) being true, and then the variable would not be bound, causing NPE. If you do need this binding to access the fact in the consequence, you should splt the rule. -W 2009/12/2 Shah, Malay malay.s...@morganstanley.com Thanks Mark.
