Hi all,
I'm a newbie for drools.
And i want to know how to fire a subset of rules in KB,
suppose there are three rules named A,B,C, and I want to fire rule A only.
by the way,
suppose there is a drl file containing rule, and i have set up KB, and call
fireAllRules through statefulKnowledgeSe
If you want to fire only a subset of rule,
you can use ruleflow-group, and you have to use Agenda to define the
ruleflow-group to use.
You'll find more infos in the drools-expert documentation on how to use those
two.

Hi Greg,
I have my input files inside the src directory of my eclipse project.
I am passing the files as follows:
private static final String DATA_INPUT_FILE = new String []{ "Input1.txt",
"Input2.txt"};
private static final String DATA_OUTPUT_FILE = "Output.1.txt";
private static final String
This isn't really a Drools question just a basic java programming question.
You are trying to read your input files from the current working directory
(which defaults to the root of your project in eclipse).
What you probably want to be doing is reading your files from the classpath
instead. Usi
The code you pasted doesn't even compile. The first line is wrong.
It looks to me that the problem you are experiencing has nothing to do with
drools itself. You can't even open the input file using a simple
FileReader... No drools api involved there. Make sure you have your inputs
files in the rig
Not a drools question, i guess...
If the files are in the src directory, you probably have to configure them
including the path (e.g. "src/Input1.txt").
When running a java class / junit, eclipse sets the project directory as the
current directory, so if you want to reach a file, you must supply th
he message, and please delete it from
your system. Thank you. NYSE Euronext.

Hi,
still struggling with this one (see below),
but I did a slide change in the test-code
try {
val env = new java.util.Hashtable[String, String]
env.put(Context.INITIAL_CONTEXT_FACTORY,
"bitronix.tm.jndi.BitronixInitialContextFactory")
val ctx = new InitialContext(en
It's probably that your transaction manager, for an odd reason, doesn't bind
with the good name;
You can do the following workaround:
Final InitialContext initContext = new InitialContext();
initContext.bind("java:comp/UserTransaction",initContext.lookup("comp/UserTransaction"));
And voila, thos

Thanks Manuel,
but the problem is that I do not have any influence on
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env )
where the problem occurs. Looks like Drools is using
"java:comp/UserTransaction" internally (within
JPAKnowledgeService.newStatefulKnowledgeSession), not
For additional information:
JPAKnowledgeService.newStatefulKnowledgeSession uses
org.drools.persistence.session.SingleSessionCommandService
where "java:comp/UserTransaction" is used (I checked the drools source
code). Looks like there is no way to change this.
I just wonder that I am the only
Hi,
I am trying out this example from the book :
public class Room {
private String name
// getter and setter methods here
}
public classs Sprinkler {
private Room room;
private boolean on;
// getter and setter methods here
}
public class Fire {
private Room room
This has nothing to do with Drools. It looks like you are giving Writer bad
input perhaps??

I am writing rule " if fire exists in room start sprinkler" { so if f1 and r1
in this case: I should get s1, r1 }
when

Then

Hi,
I was wondering how you can achieve a "group by" like this
select tickDataFeed, stddev(price)
from StockTickEvent(symbol='IBM').win:length(10)
where volume > 1000
group by tickDataFeed
having stddev(price) > 0.8
I thought of using accumulate or collect, but I'm not sure of the exact syntax
I created a sample project to run a very simple rule flow (BPMN process), I got
the similar error which the plugin is reporting. My env is SUN JDK 6. Here is
the exception I get? Any clue guys.
