I am writing a program based on CURD operation based on Spring-orm module.
//dao class
//StudentDAO.java
package com.nt.dao;
import com.nt.domains.StudentInfo;
public interface StudentDAO {
public StudentInfo getStudentInfo(int sid);
}
//StudentInfo.java
package com.nt.dao;
import org.springframework.orm.hibernate5.HibernateTemplate;
import com.nt.domains.StudentInfo;
public class StudnetInfoImpl implements StudentDAO {
//bean
private HibernateTemplate htemplate;
public void setHtemplate(HibernateTemplate htemplate) {
this.htemplate = htemplate;
}
@Override
public StudentInfo getStudentInfo(int sid) {
StudentInfo studentInfo=null;
studentInfo=(StudentInfo)htemplate.save(sid);
return studentInfo;
}
}
//service class
//studentservice.java
package com.nt.service;
import com.nt.domains.StudentInfo;
public interface StudentService {
public StudentInfo getStudentDetails(int sid);
}
//studentserviceimpl.java
package com.nt.service;
import com.nt.dao.StudentDAO;
import com.nt.domains.StudentInfo;
public class StudentServiceImpl implements StudentService {
//beans
private StudentDAO dao;
//setters
public void setDao(StudentDAO dao) {
this.dao = dao;
}
//override method
@Override
public StudentInfo getStudentDetails(int sid) {
StudentInfo info=null;
info=dao.getStudentInfo(sid);
return info;
}

When I'm trying to run this program on Tomcat 8.0 server I am getting the following exception. Can you please help me how to proceed further...
