The Eclipse JDT Core jar is not in the classpath error
by Chris Richmond
Hello,
I am using netbeans and ivy with Drools 5. I have successfully named,
published the jars from drools to and could build my port of the stock
ticker application in netbeans, but when I try to run it, I get the
following error:
java.lang.NoClassDefFoundError: org/antlr/runtime/tree/TreeNodeStream
I have the antlr-runtime jar from the bin/lib on my classpath where I added
all the others, but it always fails at this line
In loadRuleBase() in Broker.java of the stock ticker sample
builder.add( ResourceFactory.newInputStreamResource(
Broker.class.getResourceAsStream( RULES_FILE ) ),
ResourceType.DRL);.
Does anyone have any ideas what jar I might be missing if it's not the
antlr-runtime?
Thanks,
Chris

FW: Nested flow terminating parent flow prematurely
by Tom.E.Murphy＠wellsfargo.com
Thanks to Travis Scheponik for trying to help me resolve this. However, neither he nor I could figure it out.
Babak solved it here at the boot camp - the subprocesses should have their end nodes with terminate set to TRUE not false, and the parent process should invoke the subprocess with WaitForCompletion set to true.
This was the one combination we had not tried, and it worked.
Thanks, Babak.

Subject: Nested flow terminating parent flow prematurely
Hi.
I'm struggling with a rule flow that contains another rule flow.
Rule flow 1 - first step is to invoke a sub-process, call it rule flow 2.
Rule flow 2 executes fine, with correct internal branching logic.
Rule flow 2 proceeds to an End object with terminates set to false.
After RF2 completes, I am expecting a return to the parent flow, RF1.
However, entire flow terminates and subsequent RF Groups and or RF's in parent flow are never activated.
Is this a bug or am I specifying something incorrectly?
Using Version 5.0.0.CR1
Code for the two flows is below (excuse the ugly ID's and names - these are generated from our rule repository software):

String comparison question
by Armaghan Mahmud
Hey guys,
I read in a previous post that == in Drools 4.0.7 maps to .equals()
automatically. My situation required me to put a String object into the
working memory and do a comparison on it to see if a particular word is in
the passed String sentence. Could anybody please guide me as to how to
approach this problem? Thanks in advance. Here's my original code:
rule "Find Alpha in a sentence"
*
salience* 100
wrap: WrapperClass(Sentence == "Alpha")
then
System.out.*println*("Aha found ya!");
end

rule using sliding window
by Bhushan Bhangale
I am using Drools 5. I am struggling to write rule for this logic -
If a stock price changes more than 10% within an hour then report the
change.
I understand I have to use sliding window feature but unable to write the
rule.
For example I got an update for IBM stock @ 12:30 for price 100 and then
another update IBM stock @ 12:35 for price 111. Since the time difference is
within an hour and the change is also greater than 10% I want to report this
price change.
Stock class -
Public class Stock {
Private String stock;
Private double price;
Private Date time;
Private double priceChange;
Private Boolean highlight;
}
rule "Stock Price change more than 10% within an hour"
when
then
set the priceChange attribute of Stock object
set highlight to true
end
Secondly if the window is large and number of records coming in is high then
could there be a memory issue?
Also since every record is getting stored in database, can I not use the
database directly instead of sliding window?
Thanks

Clarification regarding the use of Guvnor
by Andrew Nguyen
Hello all,
I am a very new Drools user and am trying to expose it as a web-
service. Due to my experience with Spring, I went ahead and
implemented a basic rule engine and exposed it as a web service via
Spring. I am now looking at integrating it with Guvnor to allow non-
computer people, who are domain experts, to modify the rules. From
what I have read in the v5 documentation, it sounds like Guvnor is
intended as a complete solution to what I am trying to accomplish -
i.e. it will handle the rule management as well as exposing the rule
engine via JSON (or other interface). But, when I have searched
around the internet, Guvnor sounds like just a rule management
component.
So, I pretty much have 3 questions:
* Is my current setup of Drools + Spring the best way to expose my
rule engine to other applications? (Specifically, a .NET/C# app...)
* Is Guvnor suitable for integrating into my system as only a rule
management system?
Thanks!

ClassCastException for Hibernate entity when rule is fired
by Sobhana
hi, can someone please help with the below issue? Any tips or hints on what
could be causing this would be very helpful.
We are using Drools 4.0.7 and have a rule which uses a Hibernate entity
(SaleEventItem) and its related entity (Inventory). Some times, the
SaleEventItem passed as the fact has the Inventory lazy loaded and hence its
type is the Hibernate proxy - Inventory_$$_javassist_93. In this case, the
rule runs fine.
But at times, the SaleEventItem which is passed has the Inventory attribute
set explicitly and hence its type is Inventory itself. When the rule fires
in this case, it tries to assign the Inventory into
Inventory_$$_javassist_93 which causes this ClassCastException.
java.lang.ClassCastException: com.crom.data.pojo.Inventory incompatible with
com.crom.data.pojo.Inventory_$$_javassist_93
at ASMAccessorImpl_14985690421242774005070.getValue(Unknown Source)

org.mvel.ast.VariableDeepPropertyNode.getReducedValueAccelerated(VariableDeepPropertyNode.java:22)

at
org.drools.base.mvel.MVELPredicateExpression.evaluate(MVELPredicateExpression.java:45)
at
org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:209)
How do we prevent this? Is it possible to somehow enforce that the type of
the variable in the rule should be Inventory and not
Inventory_$$_javassist_93?
The rule is as follows.
dialect "java"
when
$sale:SaleEventItem(inventory != null,
$leaseInfo:inventory.leaseInformation != null,
$saleEventPrize:inventory.leaseInformation.residualPayAmount != null)
then
$sale.setStartPrice((Double)$sale.getInventory().getLeaseInformation().getResidualPayAmount());
Thanks,
Sobhana

Re: Re: Re: [rules-users] Re: Drools performance issue
by Greg Barton
It's happening because the problem is hard. :) It's quadratic on the average number of assignments per driver. i.e. for each driver, you compare all of the assignments to each other, and you must do that for all drivers. So you have ( (num drivers) * (average num assignments)^2 ) firings in the BEST case. (The rule you originally presented was pretty much the worst case, as you were matching ( (num drivers)^2 *(num trips)^2 ) )
That's also why the processing happens when you insert the second set: before that the rule doesn't trigger.
Now, if you don't need to compare trip assignments between drivers, you could just insert one driver plus their trips and fire the rules.
But if you do want to throw everything in WM at once, you may be able to use this trick: to detect overlap, you can cut the number of conditions you've got in half, making things slightly better. You only need to detect that the start or end of one of the trips is contained in another. Also, is it possible to have a driverId attribute in your trip object? That would eliminate the need to match on the driver object. Using both you'd have this:
rule "Assignment Check"
when
$ta1: TripVO();
$ta2: TripVO(
ta1.driverId == driverId,
ta1.startDtmUtc < startDtmUtc,
ta1.endDtmUtc >= startDtmUtc
);
then
Note the "ta1.startDtmUtc < startDtmUtc" instead of ta1.startDtmUtc <= startDtmUtc". This ensures that you don't test the same two TripVOs twice.
Give this a try.

Web services integration for Drools Flow
by Ajay.Gautam＠rbs.com
Hello,
I am evaluating a few workflow engines for an up coming project. Drools flow is the first one I am looking at.
Question: Is there any existing web services integration with Drools Flow? Specifically:
1. ability to call a service (Similar to "Email" work item)
2. ability to trigger a flow based on web services input (listener)
I could write a web services wrapper around Drools Flow, but am wondering if there is an existing solution for it. A quick Google search did not reveal anything much.
PS: Not looking at jBPM - don't want to get into deploying and maintaining a J2EE container. For our (simple) purposes, something like tomcat would suffice.
Any pointers in the right direction would be greatly appreciated.
Thanks
Ajay
