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);
