Mvel and import issues
by Barry Kaplan
There is a mvel bug that I run into from time to time relating to imports. I
present it here to hopefully save others from spending too much time
discovering the work around.
My drl file starts like:
import systeminsights.model.device.*
import systeminsights.event.mtconnect.*
import systeminsights.plugin.downtime.*
declare DowntimeInterval
@role(event)
@timestamp(interval.start.getMillis)
@duration(interval.toDurationMillis)
end
Every once in a while mvel will fail with ClassNotFoundException for the
class DowntimeInterval. If I change the imports to:
import systeminsights.model.device.*
import systeminsights.event.mtconnect.*
import systeminsights.plugin.downtime.*
import systeminsights.plugin.downtime.DonwtimeInterval
Then mvel finds the class. Later on, after making various edits I will
remove the redundant import and won't get the exception.
I can't reproduce this in any way -- its completely intermittent for causes
(begin:rant)
80% of the time I spend debugging drools issues ends up as an mvel quirk
(end:rant)

Newbie question on drools flow split node
by kuena
I have a process similar to one shown below that uses a split node:
start > split > [pass | fail] > ..
My constrain merely checks if the provided value is less or greater than
some fixed value, say 50. All works well except in the case where I want the
fixed value to be retrieved elsewhere. That is, if my constrain is
Result(value >50) all works but as soon as I try something like:
Parameters(max:threshold)
Result(value >max)
I get an error to the effect "XOR split could not find at least one valid
outgoing connection". I have tried a number of things but I think I am
missing something. Please help me.
thanks :-)

DRools with FLEX LCDS
by Hafeez Ur Rehman
Hello,
I am trying out DRools and I want to integrate it with Flex LCDS. I
have two projects
1. Flex Prj has
- FLEX / Flash Builder 4
- LCDS
- POSTGRESQL 8.4 ( MYSQL DB )
2. DRools Prj has
- DRools
- HIBERNATE 3.2.6
- POSTGRESQL 8.4 ( MYSQL DB )
I know how to place compiled java classes in
LCDS\tomcat\webapps\lcds\WEB-INF\classes and call a method as remote method
from Flex Prj's *.MXML file
Now considering DRools project to be actually a java application. I am
trying to compile and place the the bin folder in
LCDS\tomcat\webapps\lcds\WEB-INF\classes.
*Issue (step-by-step):*
1. Drools Prj was compiled in JRE6 it was creating an issue of with Flash
Builder 4 ===(Resulted in)===> Bad version number in .class file (unable to
load class eu.kijanowski.drools.hibernate.DroolsHibernateTest)
2. I changed the DRools JRE to JDK 1.5 ===(Resulted in)===> Now it gives
the error of "wrong name"
3. Now I placed of the bin (removed bin) in
LCDS\tomcat\webapps\lcds\WEB-INF\classes. ===(Resulted in an error alert
message)===> org/drools/WorkingMemory
I want to use DRools with LCDS. If there is a tutorial please direct me to
that. My scenario might need both of the projects to be sent. which I can,
please note.
My complete required tech stack is
- FLEX Unit
- Flex Libs + DEGRAFA + CATALYST
- Flash Builder 4 + Mate
- LCDS
- DRools
- HIBERNATE 3.2.6
- POSTGRESQL 8.4 ( MYSQL DB )
- JBOSS

high memory usage for rules with more than 6 facts as condition
by murphy
Hello,
I did some tests to get an opinion about the performance of drools (5.0.1).
At one test I have a rule with 10 objects (same object-type) declared as
condition and got an OutOfMemoryException. I noticed that the memory usage
increases when I insert the last facts into my
StatefulKnowledgeSession. On fact 7 it increases with 10MB, on fact 8 with
46MB and on fact 9 with 170MB.
I debuged a little bit in the drools-source and noticed that the
LeftTupleMemory increased exponential with the number of facts I inserted.
My question about this behaviour:
Is a condition limited to a handful of facts or do I have to change the
syntax to get it working? I know that I could insert the same object-types
as a list, but assume that I have 10 facts with different object-types.
Thanks in reply,
Christian

Grid analyzing with drools
by Vendetta
Hi folks,
I'm pretty new to Drools and try to figure out how to get the best
out of this technology.
The issue at hand is a two-layered grid analysis of a given area regarding
its threat-level, which is calculated by certain rules.
So let's get started by explaining the problem:
I have a rectangular area, which is sliced into a grid:
=> int[][] threatLvl = int[maxX][maxY], where threatLvl[myX][myY]
represents the threat-level of the certain block
I also do have information about the following:
the position of a ball (x/y)
the position of 5 friendly units (x/y)
the position of 5 enemy units (x/y)
the (constant) position of a goal (x0, y1 to y2)
the information about which team is in control of the ball
In case you were wondering: yes, it's about some kind of soccer ;)
My aim is to calculate a basic threat-level for each block based on the
following rules:
#1 a block is more dangerous, when there is a direct line between the block
and the goal (any point of the goal), which is not blocked by a
defensive/offensive unit ( => additional threat of T / 0.5*T )
#2 a block is more dangerous, when there is a direct line between the block
and the ball, which is not blocked by a defensive/offensive unit (+ threat T
/ 0.5*T)
#3 a block receives a higher threat-level for any offensive unit within a
certain range, the closer the unit, the higher the threat (something like
already calculated Threat-Amount times a factor, which is influenced by the
range)
#4 a block receives a lower threat-level for any defensive unit within a
certain range, the closer the unit, the lower the threat (something like
already calculated Threat-Amount divided by a factor, which is influenced by
the range)
Note additionally: the x/y of all units are their midpoints, the actual unit
has a (constant) radius of R, which has to be translated into an area,
effecting rules #1 and #2.
Secondly, I will divide my calculation into 2 layers in order to optimize.
At first, i will calculate the level for the midpoint of a (let's say)
5x5-block, if this block reaches a certain threat-level, i consider it
worthy being analyzed in depth, going through the rules again for every 1x1
block inside the 5x5 block.
My thoughts on solving this:
- Is this a problem i should solve with Drools (being more of a rhetorical
question ;D )
- Given it is: Should i declare one large rule (which crosses my
comprehension of drools) or can i split this up into multiple rules
- i know i can create rule-groups and control, that rules #3 and #4 are
fired after #1 and #2, in order to ensure i multiply the correct numbers
- i feel the extremely powerful accumulate functions are just what i need,
yet i can't figure how to use them efficiently in this case
Lastly, i want to state that i do of course _not_ seek some kind of complete
implementation, but rather draw on your experience and learn how to approach
this issue.
Thanks to anyone, who is willing to spend his time to think about this issue
with me :)

Drools Planner: Exception on createSolver method
by dweppenaar
Hi,
I am new to Drools in general so please excuse my noobness with some of the
concepts. I am in the process of creating a maintenance scheduling system.
As Geoffrey suggested, I have based my application heavily on the curriculum
course example included in the solver (planner) examples. I have created
most of the classes used by the example and will be implementing my gui.
I use an XmlSolverConfigurer to read the configuration from xml. The solver
config xml path is correct as I get another exception due to the file not
being found when I change the path. When the solver tries to load the xml
configuration the following exception occurs:
Exception in thread "AWT-EventQueue-0"

I am not sure why this occurs and I have also searched the forums/mailing

to see what is the cause.
Thank you in advance!

It works fine when I downloaded the 5.0 binaries and just pointed it at
this.
Plz, let me know if there is a better place to report these issues. Also,
I found a bunch of documentation nits that I'd like to eventually report.

Undeploy problem with Tomcat
by Thomas Carolan
I'm deploying a web application with drools 5.0 on Tomcat 6. Several jars remain "locked" on the file system after I undeploy the application. The jars are "drools-compiler.jar" and "drools-core.jar". I am also using a RuleFlow and that file remains locked on the filesystem when undeploying the application as well. I'm assuming that this is a ClassLoader issue or some other unreleased resource by Drools.
My question is, has anybody experienced this issue before and how can it be resolved? I'm use dispose() on the KnowledgeSession each time but I never perform any cleanup of the KnowledgeBase. Is that necessary?
I also have tried each method of adding rules/rule flows to the KnowledgeBase (File, URL, ClassPathResource) and each type has the same locking issue.

junit tests for drools rules
by Radhakrishnan Meiappan
I'm trying to test some rules from a junit test. Inside the rule the
fact is modified.
The fact is setup so that it matches the then condition in the rule, but
still my asserts are failing in my test.
How do I get the fact back from the session, after the rules are fired.
Can someone point me to a link that has samples for testing a rule from
a junit test. Its hard to find.
Thanks

Issue with drools-flow/persistence
by Daniel Ilkovich
I'm stumped. I'm trying to implement persistence with Drools-flow, and I'd
like to grab the value of a property on a workitem / processinstance, but
everytime I try to get the workitem or process instance I end up with the
stack trace below.
I'm walking through the source and from what I can tell, this happens
anytime I try and grab a property that is annotated with @Lob in an entity
class.
My environment is hibernate/mysql/JPA persistence using BTM as a transaction
manager.
These are the relevant lines of code:
ksession =
JPAKnowledgeService.loadStatefulKnowledgeSession(ksession.getId(), m_kbase ,
null, m_environment);
m_pi = ksession.getProcessInstance(m_pi.getId());
What am I doing wrong?
