Re: [rules-users] Unexpected java.lang.NullPointerException at org.drools.core.util.RightTupleIndexHashTable.removeAdd(RightTupleIndexHashTable.java:353)

You were not subscribed to the mailing list at the time, so this post did not
make it through to the main list. If you could make a self contained unit
test, we'll fix it asap. Follow details here:
http://docs.jboss.org/drools/release/5.4.0.Final/droolsjbpm-introduction-...
Take a look at MiscTest in drools-compiler to get an idea of how to write
tests.

Event-based Drools jBPM example?
by dunnlow
Hi,
I am struggling with using a process with *rule-based* flow. I have seen
looked at the canned ("evaluation") example but it is not rule-based. The
other examples I have found are really simple (like a print "HELLO" example)
where they just set up the "process," issue a fireallrules, then the node
triggers and process ends (basically just making a *decision *vice *process
*diagram -- but I could do that just using a few rules (rather than relying
on a process).
I envision setting up a true, event-based process flow to track a long
running business process. Basically, a system generates events, sends them
to a jBPM process and that state (active node?) of that process changes as
appropriate. (I will be making queries to determine the state of the
process - also will probably use jBPM console)
This seems like an obvious use-case, but I have been unable to find a simple
example of a *rule based* jBPM process that uses ONLY events. For example
start -> wait for event Message where message text = "HELLO", print "HELLO
received"
-> wait for event Message where message text = "THERE", print "THERE
received"
-> wait for event Message where message text = "JOE", print "JOE
received"
-> print "DONE"
Thus, I'd have a start and end node and three intermediate business rule
nodes. I want this to be a true sequential process such that the second
node (ie the printing of "THERE") is not reached (doesn't activate?) before
an event is received where the text="HELLO".
I've tried setting this up and got an earlier recommendation of using a
"condition" in the metadata - but this seems a bit like a kludge when a
Business Rule node exists (https://community.jboss.org/thread/205952).
Also, in reality I'd like to be able to have some slightly complex business
rules in those nodes.
Can someone PLEASE point me to an example of this (or make a suggestion on
how to implement it)?
I'm also confused about how the fireallrules works. When my system sends an
event and I insert it into my process, doesn't fireallnodes do just that -
send to all nodes thus basically breaking the whole "process flow"
methodology?
I thought I could add a rule that would ensure that the rule node was
"active" (thus per documentation not allowing the process to continue) by
putting a rule on node1 with a condition like
"when Message(text!="HELLO")"
But that still doesn't keep the second node from firing.
Sorry for the lengthy post. Any other information/writeup about using rules
with a process I'd GREATLY appreciate. (Obviously, I've been through the
JBoss web site documentation, 10 min tutorials, etc etc.)
Thanks!
-J

MVELDialectRuntimeData; local class incompatible
by TonyN
I am trying to upgrade from 5.2Final to 5.4final and ran into this error. It
seems that the rule engine (5.4) is having a hard time building the Knowlege
base using PKG directly from Guvnor 5.4. It has no issues with DRL though.
Both the Drools Engine and the Guvnor are running Java 1.6.0_20.
Both are at 5.4Final.
Not sure where, what to check next, thanks a millions.

Tuesday - General Drools&jBPM Workshop (free)
8.00 AM: Breakfast Social – pre-laptop setup, and QA time with solution Architects.
-Key will be provided to setup your laptop, so you can view and run the examples used during the talks.
9.00 BRMS Product Overview (Prakash Aradhya 15min)
How we turn the Drools and jBPM communtiy parts into a world class product. Supporting and harvesting all the innovation done in the open community, Red Hat delivers reliable, dependable and integrated solutions for enterprise customers.
9.15 Introduction to Drools Expert (Mark Proctor 45min)
Drools Expert covers the business rule engine. A gentle, example driven, dive into the Drools technical rule language and engine features.
10.10 Introduction to Drools Fusion (Edson Tirelli 45min)
Learn how Drools does CEP differently. Our unified approach extends Drools Expert with a series of language and sub-engine extensions to provide temporal reasoning and event correlation.
11.05 Introduction to jBPM and BPMN2 (Tihomir Surdilovic 45min)
jBPM is a BPM engine designed for flexible processes, implementing and extending the BPMN2 spec. Built form the ground up to be part of a unified strategy for business automation and decision management. jBPM fully integrates with Drools Expert and Fusion.
11.45 Decision Modelling with Graphical Editors (Edson Tirelli 30min)
Drools Expert provides sophisticated web based tooling, around decision tables, guided editors and templates. Our decision modelling approach draws from the very best research found at Dr Jan Vanthienien school of Decision Modelling.
12.30 Working Lunch – Experience Drools and jBPM – Hands on labs (Optional) (1hour)
13.30 Human Tasks up Close and Personal (Tihomir Surdilovic 40min)
Human tasks are a central component of BPM. This example driven talk will build an example live, demonstrating what jBPM’s Human Task technology can do for you.
14.20 Building Games with Drools – Pong, Snake and Wumpus (Mark Proctor 40min)
Time for some hard play, learn how to build classic computer games with Drools. These also provide interesting exercises in BA requirements gathering.
15.10 Drools Planner a Quick Overview (Geoffrey De Smet 40min)
Whether it’s employee rostering, task scheduling, vehicle routing, bin packing or another planning problem: all organizations try to optimize their limited resources under constraints. Drools Planner optimizes business resources for normal Java programmers.
15.50 Drools Chance for Imperfect Reasoning (Davide Sottara 40min)
Sometimes data quality is not perfect, so facts may not be known with precision and certainty. Likewise, crisp constraints such as hard thresholds might not be able to capture the complexity of a business policy. Drools Chance allows to apply gradual and/or probabilistic constraints to uncertain or vague data.
16.40 UberFire – Drools&jBPM Workbench framework (Mark Proctor 30min)
UberFire is a new project that forms the foundation of our 6.0 web tooling. It’s standalone framework that provides a sophisticated workbench framework for the web; where everything is a plugin. Come learn about the Uberfire, and how you can use the workbench to build your own web applications.
17.10 Drools&jBPM 6.0 and Beyond (Optional : open as long as people remain)
An open presentation and discussion about the design ideas, principles and goals that are driving the development of Drools & jBPM version 6.0.
