[rules-users] Problem with Drools 4.0.3

Hello all I am using Drools4.0.3 I have a J2EE application that I am running on Tomcat. I am using a singleton class in which I am doing the following steps in the constructor : PackageBuilderConfiguration pkgBuilderCfg = new PackageBuilderConfiguration(); JavaDialectConfiguration javaConf = (JavaDialectConfiguration) pkgBuilderCfg.getDialectConfiguration( "java" ); javaConf.setCompiler( JavaDialectConfiguration.JANINO ); builder = new PackageBuilder(pkgBuilderCfg); ruleBase = RuleBaseFactory.newRuleBase(); Also I am using a method in the same class to validate the inputs which is as follows: private void validateXML() throws Exception { String drlStr = null; InputStreamReader drl = null; File ruleFile = new File(this.fileName); long curLMTime = ruleFile.lastModified(); if(!(curLMTime == lmdTimeForXML)) { lmdTimeForXML = curLMTime; if(strReader != null) { strReader.close(); strReader = null; } if(pkg != null){ String packageName = (ruleBase.getPackage("jbossrules")).getName(); if(packageName != null && packageName.equals("jbossrules")){ Rule[] rules = (ruleBase.getPackage("jbossrules")).getRules(); if(rules != null){ for (int i=0; i<rules.length; i++){ String ruleName = rules[i].getName(); try { ruleBase.removeRule(packageName,ruleName); }catch(NullPointerException ne){ } } } } } try { drl =new InputStreamReader(new FileInputStream(this.fileName)); drlStr = this.getInputStreamAsString(drl); strReader = new StringReader(drlStr); builder.addPackageFromXml(strReader); pkg = builder.getPackage(); ruleBase.addPackage(pkg); } catch (IOException e) { e.printStackTrace(); log.error("*********Can not create inputstrea************", e); lmdTimeForXML = 0; throw e; //removeRules(); }catch (Exception e) { e.printStackTrace(); log.error("*********CAN NOT CREATE THE RULE BASE INSTANCE************", e); lmdTimeForXML = 0; throw e; //removeRules(); }finally { try { if(drl != null) { drl.close(); } } catch (IOException e) { e.printStackTrace(); log.error("*********Can not create inputstrea************", e); } } } StatefulSession session = ruleBase.newStatefulSession(); session.insert(this.beanObj); session.setGlobal("response",this.response); if(this.assertObjArr != null && this.assertObjArr.length > 0) { for(int i=0; i<this.assertObjArr.length; i++) session.insert(this.assertObjArr[i]); } Agenda agenda=session.getAgenda(); AgendaGroup agendagroup=agenda.getAgendaGroup(this.getMethodName()); session.setFocus(agendagroup); session.fireAllRules(); ResponseBean res = (ResponseBean)session.getGlobal("response"); this.setResponse(res); session.clearAgenda(); session.setGlobal("response",null); session.dispose(); session = null; } Now when I am deploying any wrong rule,it gets stored in the memory.If again I am deploying the rules then the previous wrong rules are not deleting. Please suggest me how can I overcome this problem?
