Hi All ! I have an existing web application "Bonus Calculation Management System" which has been developed in servlet and Hibernate which is interacting with DB. I have developed a product in Drools using Struts. Now the task is I have to integrate this drools product in the Existing Servlet application. I have integrating it converting Struts to Servlet. But it is giving this exception about my Rule File : * com.drools.action.PolicyAction hurrrrrrrrrrrrrr java.io.FileNotFoundException: Cannot find rule file:Sample.drl at com.drools.facts.RuleRunner.loadRuleFile(RuleRunner.java:89) at com.drools.facts.RuleRunner.loadRules(RuleRunner.java:67) at com.drools.facts.RuleRunner.getStatefulSession(RuleRunner.java:227) at com.drools.facts.RuleMain.main(RuleMain.java:46)* *In my Servlet class I have written like this :* public int calculate(HttpServletRequest req, String schId,String schStepID, Date clcFrDate, Date clcToDate,String runNo) { System.out.println("hurrrrrrrrrrrrrr"); InputFormBean inputFormBean=new InputFormBean(); inputFormBean.setFromDate(clcFrDate.toString()); inputFormBean.setToDate(clcToDate.toString()); String fromDateArray[]=inputFormBean.getFromDate().trim().split("/"); String toDateArray[]=inputFormBean.getToDate().trim().split("/"); inputFormBean.setFromDateArray(fromDateArray); inputFormBean.setToDateArray(toDateArray); RuleMain ruleMain=new RuleMain(); try { ruleMain.main(inputFormBean); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return 0; } *In the RuleMain.java* : public class RuleMain extends HttpServlet { private final String[] RULES_FILES8 = new String[] {"Sample.drl"}; // *I also tried : com.drools.rules/Sample.drl but dint work* static HashMap<Integer, Double>agntAPEMap=new HashMap<Integer, Double>(); public void main(InputFormBean inputFormBean) throws Exception { HashMap<String, Object> globals = new HashMap<String, Object>(); //globals.put("index", new Index(0)); StatefulSession statefulSession=new RuleRunner().getStatefulSession(RULES_FILES8,null,null, globals, null); ...... ........
