Re: [rules-users] accumulate funtion in xml

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 Fernando Meyer Camargo wrote: > > Hi isabelle, > > When I said instance class, I was meaning your instance source code ;) > > Regards > > On 9/28/07, Isabelle Hupont <ihupont(a)ita.es&gt; wrote: >> >> >> Hi Fernando! >> >> Mi Instance class is the Weka class I attach.... >> Thanks for your attention. >> Isabelle. >> http://www.nabble.com/file/p12935480/Instance.class Instance.class >> >> >> >> Fernando Meyer Camargo wrote: >> > >> > Could you please provide your Instance class ? >> > >> > >> > On 9/27/07, Isabelle Hupont <ihupont(a)ita.es&gt; wrote: >> >> >> >> >> >> 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 < 20000) >> >> 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" >> >> xs:schemaLocation="http://drools.org/drools-4.0 drools-4.0.xsd"> >> >> <import name="weka.core.*"/> >> >> <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;tend&quot;)"/> >> >> </accumulate> >> >> </from> >> >> </pattern> >> >> <eval>_average &lt; 20000.0</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.
