Re: [rules-users] Drools and JBoss 6.0 Support
There is still problem running Guvnor 5.1(not 5.0.x. Some improvements have been made in Guvnor 5.1 to make it working with AS 5.x) on JBOSS AS 6. The main blocker is running Seam 2.1 with JBOSS AS 6, you may search in Seam forum for possible workaround. To be honest, I would suggest you using JBOSS AS 5.X instead. Running Guvnor with As 6 is not on a priority list. Cheers, Jervis On 2010/10/7 8:50, Robert Morse wrote: > Hello, > Is there any update to this?

[rules-users] Guvnor LHS and RHS questions
Hello, I've only been working with Drools for a little over a month or so now and I've begun integrating it into my application via Eclipse and creating DRL files. The nature of this application is to take a data record from one file and create a new data record in another file. This is done in a batch of any number of records, depending on the number of records sent to us in the first file. To accomplish this I have two classes, one representing each file, and I create and object for each of them, inserting them into the knowledge session and then fire the rule. ksession.insert(myObjectIn); ksession.insert(myObjectOut); ksession.fireAllRules(); The first object has around 1,000 fields and the second has 250, so my class structure is quite broad. In a DRL file I have created the following rule: rule "Primary Diagnosis Code" when $ccl : anObjectIn(IncomingDiag1 != null) $cdl : anObjectOut() then $cdl.PrimaryDiag = $ccl.IncomingDiag1; end This rule fires great and the PrimaryDiag field in myObjectOut is updated with what iss in myObjectIn.IncomingDiag. I can then write the object back out the the database fine. A requirement of my project is that I allow users (analysts) to create their own rules that are above and beyond those I might create in a .drl file. To do so we are looking to deploy Guvnor and let them use the Guided editor to create rules. I've already loaded my fact models into Guvnor and have them available in the drop down conditions. The questions that are hitting me now are: 1) On the LHS when I've chosen the fiels IncomingDiag the only options I have for conditions are "equal to", "not equal to", "matches", and "sounds like". I don't see an option for null or notnull. If I were to choose "not equal to" I then have the options for Literal Values, New Formulas, or Expression Editor (which has none by default). I haven't seen any examples where someone is evaluating a field in Guvnor for being either "" or null. How would one accomplish this? The literal value does not allow you to leave it blank as in "" and if you type "" in it, the source shows . 2) On the LHS, if I were to want to evaluate IncomingDiag1 == IncomingDiag2 I don't see a method except if I were to choose New Formula and type in the field name Incoming Diag2. Is there another way that they could be prompted for the field choises again? 3) On the RHS, when I go to add a new then, I'm prompted to choose only to either "insert fact anObjectIn" or to "logically insert fact anObjectIn" or to manually enter DRL logic. Both of the inserts appear to create logic that would create a new object with the data in it: anObjectIn fact0 = new anObjectIn (); fact0. IncomingDiag1 ( 11 ); insertLogical(fact0 ); But what I really want is something similar to my DRL from above. Am I missing something? Or would this have to be a case where they would manually enter the DRL statement? Thank you!

Re: [rules-users] Rule id / Rule name
If you really need the rule name in the consequence you can also access the
implicit KnowledgeHelper instance "drools":-
rule "test"
when
eval(true)
then
System.out.println("Rule name = " + drools.getRule().getName());

Re: [rules-users] Memory usage tied to rule report?
Hi Jared,
This was really a first attempt at getting something useful to look
inside the chest of a session and extract useful info. Feel free to
look at the classes and propose changes/provide patches. Once it
reaches a state we consider good enough, we can publish it in Drools
API.
Regarding use of "instanceof", I always prefer to use polymorphism
instead. So, define a method to do what you need in a super
class/interface and we implement it in all subclasses. Besides making
the code cleaner, this also makes sure that new nodes/classes created
in the future will not break or be absent in the report.

[rules-users] Could not initialize class org.drools.rule.builder.dialect.java.JavaDialect
Ok, I have been struggling with this error for days now. I am getting a NoClassDefFoundError: Could not initialize class org.drools.rule.builder.dialect.java.JavaDialect error. I understand that this is most likely a classpath problem but have done almost everything to try and resolve it. I have the drools-compiler-5.1.0.jar in my lib folder where all my other jars are (which successfully work btw) and adding this jar there resolves a packagebuilder error also. Does anyone have any idea? The JavaDialect.class files are in the jar if I open it with 7zip...so it's not like they are not there. I'm really at a loss with this one now. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Rule id / Rule name
Btw, is there a more elegant way to get from Drools the rule he caught?
my way foeces the user to set the ruleId for each rule he writes.

Hi,
I would like to return to the Fact object the rule id that was caught
my facts class has a memeber
String caughtRule;
and set and get
setCaughtRuleId (String s) { caughtRule= s;}
String getCaughtRuleId () {return caughtRule;}
my rule looks like:
rule "01"
salience 100
activation-group "mygrp"
no-loop true
when
d : CFactClass( someMember matches "some-string");
then
System.out.println("01 caught");
d.setCaughtRuleId("01");
d.setCaught();
end
when the rule is fired i see the the setCaught() worked (its a boolean
variable) but the setCaughtRuleId methids return empty string...
any ides?
Thanks

Thanks for the sample code. I also explored other operators in the jboss
code base and now have a fairly good understanding of it.
In my use case I have a fixed set of values in the right side of of the
operator. Only the left side changes as input fact --
when
MyContext(inputSetOfStings subsetOf ("StringVal1", "StringVal2",
"StringVal3", "StringVal4"))
How do I construct this rhs of the operator such that it is taken as a
collection when the rule is compiled?

[rules-users] Spring , Ruleflow and KnowledgeBuilderConfiguration
I'm using drools flow in my spring application and am currently using the following to configure the kbase I use: When I run I'm getting a big error: Process Compilation error : org.drools.lang.descr.processde...@7a40fc vcm/ingest/Process_vcm_ingest_0.java (7:281) : Syntax error on tokens, ( expected instead vcm/ingest/Process_vcm_ingest_0.java (7:281) : The left-hand side of an assignment must be a variable ... Firstly it looks like ProcessDescr needs a sensible toString method implemented - preferably actually saying which resource it is attempting to compile. I'm guessing that I've got some syntax errors in my ruleflow file (even though the eclipse plugin claims it validates fine). I've seen that the knowledge builder configuration has the option drools.dump.dir, but how can I set this within Spring?

[rules-users] Can Drools Flow Persistence Work without JTA
Hi list, According to the documents and some test cases, I found that Drools Flow persistence examples have to work with JTA to enable transaction management. Is there some way to not use JTA as my transaction manager? -- 唐睿 ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] OOME on JPA persistence of stateful session
Hi,
I'm trying to use JPA persistence for a stateful session (version 5.1.1),
the configuration is made using spring integration support.
During the integration tests almost always I get an OutOfMemoryException. I
chased the problem to the piece of code bellow (from
org.drools.marshalling.impl.OutputMarshaller).
The "for" statement marked "HERE" will cycle for ever (until no more memory
is left).
I also found the
http://www.mail-archive.com/rules-users@lists.jboss.org/msg12427.html
thread, I took out my split, but problem did not go away.
Cheers,
Dan
