[rules-users] Drools - Query Problem

Dear All, I have created simple rule file and created model in that rule file only package com.sample import java.lang.String; declare Rating rate : int band : String name : String end query "employee with band E" ratg : Rating(band == "EBand") end rule "for E band" when r : Rating( rate == 1) then r.setBand("EBand"); System.out.println( "in E band" ); end rule "for D band" when r : Rating( rate == 2) then r.setBand("EBand"); System.out.println( "in E band" ); end rule "for C band" when r : Rating( rate == 3) then r.setBand("EBand"); System.out.println( "in E band" ); end rule "for B band" when r : Rating( rate == 4) then r.setBand("EBand"); System.out.println( "in E band" ); end At the end I want to know how many employees have got E band and so have written query for it in the rule file .and obtained the query results as below FactType bandType = kbase.getFactType( "com.source", "Rating" ); QueryResults results = ksession.getQueryResults( "employee with band E"); System.out.println( "we have " + results.size() + "employee with band E" ); System.out.println( "employee with band E:" ); for (Iterator i = results.iterator(); i.hasNext();) { QueryResultsRow row = (QueryResultsRow)i.next(); Object ratg = row.get("rating"); String name = (String) bandType.get( ratg, "name" ); System.out.println(name); } But am getting the result of query as 0 records. i am inserting objects one by one ( this for testing just purpose ) to learn how query works. Can someone plz point out what is wrong.Its Urgent ................ Thanks in advance.
