NPE when dumping XML -------------------- Key: JBRULES-746 URL: http://jira.jboss.com/jira/browse/JBRULES-746 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Components: Drl Parser/Builder Affects Versions: 3.1-m1 Reporter: Edson Tirelli Assigned To: Edson Tirelli Fix For: 3.1-m2 REPORTED BY SANJAY SINGH --------------------------------------------- What is wrong with this drl file ? When i try to create a xml out of it .. it keeps on failing on me .. while testing things out the rule works just fine .. its just the XmlDumper class which throws exception (InvocationTarget) .. Anybody else tried to generate xmls from drl files .. there are not many examples for the latest syntax of XML so i thought to create the DRL's first and then generate XML's off them .. but a very basic Drl failing is just killing my enthusiasm to go on with drools .. DRL package com.walmart.itemfile.item.rules import com.walmart.itemfile.item.vo.ItemVo; import com.walmart.itemfile.item.dao.ItemDao; import com.walmart.itemfile.item.dao.ItemValidationDao; import java.lang.String; global com.walmart.itemfile.item.dao.ItemValidationDao itemValidationDao; global com.walmart.itemfile.rules.ValidationErrorMap errors; rule "Item status sode cannot be null" when item : ItemVo(itemStatusCode == null) then errors.addValidationError("nullItemStatusCode","Item Status Code is null"); System.out.println("Item Status Code is " + item.getItemStatusCode()); end JAVA DrlParser parser = new DrlParser(); final PackageDescr pkgOriginal = parser.parse( new InputStreamReader( getClass().getResourceAsStream( "testRules.drl" ) ) ); final XmlDumper dumper = new XmlDumper(); final String result = dumper.dump( pkgOriginal ); EXCEPTION ...
