drools - How to remove Rules which are having errors -

i having list of rules created dynamically. after created check whether there errors. cannot find way remove rules having errors dynamically.

 public void validaterule(list<string> rules, collection<abstractfact> facts) {         kieservices kieservices = kieservices.factory.get();         kiefilesystem  kiefilesystem = kieservices.newkiefilesystem();          int ruleindex = 0;         (string rule : rules) {             stringbuilder rulename = new stringbuilder("src/main/resources/rule");             rulename.append(ruleindex).append(".drl");             kiefilesystem.write(rulename.tostring(), rule);             ruleindex ++;         }         kiebuilder kiebuilder = kieservices.newkiebuilder(kiefilesystem).buildall();          if (kiebuilder.getresults().hasmessages(message.level.error)) {             //remove rules failing           }          kiecontainer container = kieservices.newkiecontainer(kieservices.getrepository().getdefaultreleaseid());          kiesession ksession = container.newkiesession();          (abstractfact fact : facts) { // insert facts             ksession.insert(fact);         }         ksession.fireallrules();     }  

drools file validation

template header  name  package test;   template "test template"  rule "test rule"  when      $fact : fact(code != )  // expression wrong intentionally      $fact.setok(false);  end  end template 

write each rule kiefilesystem file try.drl , call buildall. keep track of filing rules.

delete try.drl.

in second pass, write now, skipping rules failed in first pass.
