 Hi!

 I want to program the following drl rule in xml:

 rule average calculation
 no-loop true
 when
 _i : Instance()
 _average : Double()
 from accumulate(accInst: Instance(),
average(
 accInst.value(tend)))
 eval(_average  2)
 then
 _i.setValue(tend,2000);
 end


 For it, I have implemented the following xml file:

 ?xml version=1.0 encoding=UTF-8?
 package name=org.prophet.fuzzy xmlns=http://drools.org/drools-4.0;
 xmlns:xs=http://www.w3.org/2001/XMLSchema-instance;

 import name=org.prophet.gui.docking.*/
 import name=org.prophet.persistence.*/
 import name=org.prophet.persistence.hibernate.*/
 import name=org.prophet.rules.*/
 import name=org.prophet.*/
 rule name=Rule1
 rule-attribute name=no-loop value=true/
 lhs
 pattern identifier=_i object-type=Instance/
 pattern identifier=_average object-type=Double
 from
 accumulate
 pattern identifier=accInst
 object-type=Instance/
 external-function evaluator=average
 expression=accInst.value(quot;tendquot;)/
 /accumulate
 /from
 /pattern
 eval_average lt; 2.0/eval
 /lhs
 rhs
 _i.setValue(tend, 2000.0); manageRuleFired(Rule1, null, _i);
 modify(_i);/rhs
 /rule
 /package

 And I have the following error when reading the rule package:

 org.drools.rule.InvalidRulePackage: Rule Compilation error _average
 cannot
 be resolved _i cannot be resolved _i cannot be resolved _i__Handle__
 cannot
 be resolved _i cannot be resolved


 I also have tried to replace the xml identifier pattern by column
 with
 no result. Can you help me, please?

Re: [rules-users] accumulate funtion in xml

2007-09-28 Thread Isabelle Hupont 

Sorry!! I mixed the .class and. java files!! ;)
Here is the source code. I also paste the code I am using to read the rule
package: 

public RuleBase readRulePackage() throws PersistenceException{
// Reads a set of rules from XML file
try {   

PackageBuilder builder = new PackageBuilder();
builder.addPackageFromXml(new InputStreamReader(new
FileInputStream(ruleFile)));

ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(builder.getPackage());
return ruleBase;

} catch (Exception e){
e.printStackTrace();
throw new PersistenceException(Error reading rules 
file);
}
}

thx! http://www.nabble.com/file/p12935779/Instance.java Instance.java

 Hi Fernando!!

 I have fixed the problem... I didn't changed drools v3 modify(_i)
 statement
 by drools v4 update(-i).
 Now everything works well!
 Thanks a lot for your attention.
