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?
With Regards
Prateek
