How to traverse the Collection by index
by dhari
Hi all,
I want to compare all elements in the collection with other element of the
same collection. In my case I have collection of Segment, a Segment contains
startDate and endDate. The whole collection of Segment should consists on
complete calendar year and every segment in the list must start 1+ from the
endDate of last element. Valid fact should be:
MemberShip
Segment 1: StartDate: 01-01-2010 EndDate: 30-05-2010
Segment 2: StartDate: 31-05-2010 EndDate: 08-08-2010
Segment 3: StartDate 09-08-2010 EndDate: 31-12-1020
Data structure
class Segment{
java.util.Date startDate;
java.util.Date endDate;
}
class Membership{
java.util.ArrayList<Segment> segments;
}
I know the date functions. I just want to know how can I traverse the List
from get element on Index and Index+1?

Task Server gives error cannot use getTransaction()
by Todd Pagni
When I configure the Task Server(org.drools.task) to be JTA I get the
following error when adding a Human Task work item. Is the following
Persistence Unit configuration valid? It works when the org.drools.task
trans type is set to LOCAL_RESOURCE.

Missing Component types in Drools Flow 5.1 SNAPSHOT Eclipse plugin?
by Alan.Gairey＠tessella.com
I've just deployed the latest 5.1 snapshot (revision 3724) of the Drools
Eclipse plugin. In the Drools Flow graphical editor, the 'State' and 'For
Each' component types are still not present in the Components palette.
Presumably these will be added prior to the actual 5.1 release?
Also, I've noticed that characters such as &, <, > etc. used within
property values (e.g. the process name) are not escaped when written out
to XML. Needless to say, this can cause problems.
Regards,
Alan

Spring jars for Drools 5.0
by Agrawal, Swapnil
Hi
Do we have all spring jars compatible to Drools 5.0?
I am trying to upgrade my current Drools 3 app to Drools 5 and see logs :
Destroying singletons in {org.springframework.beans.factory.support.DefaultListableBeanFactory defining beans ..........}
Looks like this could be related to the old spring jars that I am using which are not compatible with Drools 5
Appreciate your help.
Thanks

Data directly from Monitoring tool
by Nina
Hello,
In there any way to receive events directly from a monitoring tool to
trigger a rule flow within the Drools suite? If yes, which component would I
leverage (e.g. Flow, Fusion) and how would I set this up (e.g. adapters)?
Thank you.

java.lang.NullPointerException at:kbuilder.add(ResourceFactory.newByteArrayResource(drl.getBytes()), ResourceType.DRL)
by misge_
I have the problem that the DRL file is correctly loaded (i can see it at my
system out with the content).
But when it comes to this line:
kbuilder.add(ResourceFactory.newByteArrayResource(drl.getBytes()),
ResourceType.DRL);
I have tried also the :
// kbuilder.add(ResourceFactory.newInputStreamResource(finp),
ResourceType.DRL);
// kbuilder.add(ResourceFactory.newFileResource(path),
ResourceType.DRL);
but I have always the following stacktrace:

Multi-tenant environment

Hello,
Does anyone have any experience with leveraging a Drools instance for
multiple clients/projects? I'm wondering how this works in terms of security
and how to architect the rules repository to handle this. As well as, how we
can architect rules services to leverage a base set of rules for all clients
and then run specific ones.
Thank you.
