        at com.model.Student_College.main(Student_College.java:31)


Now i am sending my main class and .xls file.

public class Student_College {
       
        public static void main(String args[]) throws IOException
        {
               
                Student s=new Student();
                College c=new College();
                s.setAge(20);
                s.setMarks(35);
                c.setRanking("B");
                c.setLocation("elhi");
               
               
               
                try
                {
                        KnowledgeBase kbase = readBase();
                        StatefulKnowledgeSession ksession  = kbase.newStatefulKnowledgeSession();
                       
                        ksession.insert(s);
                        ksession.insert(c);
                        ksession.fireAllRules();
                        System.out.println("Department is "+s.getDepartment());
                       
                        System.out.println("Status is " + c.getStatus());
                         
                        ksession.dispose();
                       
                       
                       
                }
                catch(RuntimeException re)
                {
                        System.out.println("Error in main ...");
                        re.printStackTrace();
                        System.out.println("Error is "+re);
                       
                }
               
        }
       
        private static KnowledgeBase readBase() throws IOException
        {
                DecisionTableConfiguration dconf = KnowledgeBuilderFactory.newDecisionTableConfiguration();
                dconf.setInputType(DecisionTableInputType.XLS);
               
                KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
                kbuilder.add(ResourceFactory.newClassPathResource("manohar.xls", Student_College.class), ResourceType.DTABLE, dconf);
               

            if(kbuilder.hasErrors())
                {
                        System.out.println("Error in kbuildefr ......");
                        throw new RuntimeException(kbuilder.getErrors().toString());
                       
                }
               
                KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
                kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
                 
                return kbase;
               
               
        }

}


In above main class i used the following code to interpret my manohar.xls file...

String drlString = null;
                try {
                        drlString = DecisionTableFactory.loadFromInputStream(ResourceFactory.newClassPathResource("manohar.xls", Student_College.class).getInputStream(), dconf);
                } catch (IOException e) {
                        // TODO Auto-generated catch block
                        System.out.println("Error in drl String .....");
                        e.printStackTrace();
                }
                 
                  System.out.println("..........."+drlString);




manohar.xls:
