Re: [rules-users] Drools 5.1.0.M2 - BPMN2 process issue - Eclipse plugin. -- The method getTextContent() is undefined for the type Node
by Vijay K Pandey
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.
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
The method getTextContent() is undefined for the type Node

Subject: Drools 5.1.0.M2 - BPMN2 process issue - Eclipse plugin. -- The method getTextContent() is undefined for the type Node
Hi,
I just downloaded the Drools 5.1.0.M2 (have been using the snapshot version of around 16th April 2010) - created a sample "rule flow file(start-->user task-->end) - bpmn2 version". But when I clicked the file to open it gave the following error (image attached)
"The method getTextContent() is undefined for the type Node" .
I understand this error is related to org.w3c.dom.Node where this method was added as part of DOM Level 3 and available in JDK 5+ . My project and eclipse is configured against JDK 6+ . Not sure why this error with M2.
May be it is because of the drools-bpmn2.jar included in the drools eclipse plugin? Can someone shed some light that where it might be going wrong.

Fusion: Group By
by Andreas Bauer
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. What I tried up to now
rule "test"
when
$event : CountEvent() over window:time( 15s ) from entry-point "Stream"
$grouped : Integer() from accumulate (CountEvent($c1:count), count($c1))
then ...
But that doesn't work. Any hints?
Best regards,
Andi

Re: [rules-users] Multiple Object Referencing error
by Fnu Mahalakshmi
Hi David,
I am giving it the input exactly as I put up. It seems to be fine.
Could it be because there are new objects of room formed even though the attributes they hold are similar???
Thank you
M

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 one having this problem.
As I said "comp/UserTransaction" works, but "java:comp/UserTransaction"
doesn't, but in the docs "java:comp/UserTransaction" is used !?!?!?
Cheers, Rob.

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;
// getter and setter methods here
}
I load 2 input files: 1. with data of fire and Room { f1, r1;f2, r2}
2. with data of sprinkler and Room { " ", r1; " " , r2}
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
Fire($room : room)
$sprinkler : Sprinkler( room == $room, modified == false )
Then
$sprinkler.setmodified(true);
modify( $sprinkler ) { setSprinkle( "s1" ) };
end
But this gives me error:
Exception in thread "main" java.lang.NullPointerException
at java.io.Writer.write(Unknown Source)
at com.org.RulesTest.main(RulesTest.java:58)
>From what I observed this rule is not getting fired at all.
I want this rule to be fired on the data in my second input file.
The rules for my first input file get executed properly.
Can any1 tell me where I am going wrong??
Is there any way in which we can use the modified data { after rules are fired on the first input data and it is modified}to fire another set of rules on the same input depending on the next input file???
Thank you.

Hi Greg,
It was my mistake and a very basic java question. But you need not be rude for that.

Hi Thomas,
Thanks a lot for the help.
I am also facing problem in uploading my modified working memory back to my output file.
Once the rules are fired and the data in my working memory is modified how do I reupload it to my text file?
I store all my data in a vector which loads it to the working memory.
Could you point me towards some documentation which explains it?
Thanks so much.

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 RULES_FILES = new String [] {"Rule1.drl", "Rules2.drl"};
public static void main(String[] args) throws Exception {
BufferedReader input = new BufferedReader(new FileReader(DATA_INPUT_FILE));
Converter c = new Converter(DATA_INPUT_FILE); // this reads my input files
Vector<Object> v = new Vector<Object>();
v = c.getFactInput(); // loads all information contained in the input files
new RuleRunner().runStatelessRules(RULES_FILES,null, v,null); FileOutputStream output = new FileOutputStream(DATA_OUTPUT_FILE);
Error Log:
Exception in thread "main" java.io.FileNotFoundException: Input1.txt (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
at com.org.RulesTest.main(RulesTest.java:29)
Can you tell me why that happens??
The file is present.
Thanks.

how to fire a subset of rules in KB?
by wenjinchao
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 statefulKnowledgeSession. After that, the rule file is changed, how to load rules dynamicly?
Is there any solution?
Thanks in advance!
best regards.

Drools 5.1.0.M2 - BPMN2 process issue - Eclipse plugin. -- The method getTextContent() is undefined for the type Node
by Vijay K Pandey
Hi,
I just downloaded the Drools 5.1.0.M2 (have been using the snapshot version of around 16th April 2010) - created a sample "rule flow file(start-->user task-->end) - bpmn2 version". But when I clicked the file to open it gave the following error (image attached)
"The method getTextContent() is undefined for the type Node" .
I understand this error is related to org.w3c.dom.Node where this method was added as part of DOM Level 3 and available in JDK 5+ . My project and eclipse is configured against JDK 6+ . Not sure why this error with M2.
May be it is because of the drools-bpmn2.jar included in the drools eclipse plugin? Can someone shed some light that where it might be going wrong.

Re: [rules-users] Error Loading multiple input files
by Greg Barton
How are you translating the input file into POJOs? Not being able to find a file on your system has little to do with drools.
Can you list the code that throws the FileNotFoundException?

Hi,
I have 3 separate text files with my input data. I need to load all the input files data to my working memory and then fire the rules on this data.
I am able to work with just 1 input file. But when I try to add multiple files - which I tried by adding an array of input files - my program terminates giving me a FileNotFoundException.
Same problem occurs if I try to add an multiple .drl files ( different rule files).
Can you guys please help me. Not understanding how to solve this error.
Also, how can I add my modified data to a new file. My new file gets created and the rules which are fired do modify my data as required ( printed it on the console)
But how do I store this information back to my working memory and print it out to my output file.
All my input files have only 1 field in common otherwise are not related.
Is it a better option to have all data in only 1 input file??
Thanks you.
