I have three files in my project.
1.EmpDAO.java:
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
import org.springframework.dao.DataAccessException;

import org.springframework.jdbc.core.simple.SimpleJdbcTemplate;
public class EmpDAO {
private JdbcTemplate template;
public JdbcTemplate getTemplate() {
return template;
}
public void setTemplate(JdbcTemplate template) {
this.template = template;
}
public List<Student> getAllStudents(){
return (List<Student>) template.query("select * from test",new ResultSetExtractor(){
#Override
public List<Student> extractData(ResultSet rs) throws SQLException,
DataAccessException {
List<Student> list=new ArrayList<Student>();
while(rs.next()){
Student e=new Student();
e.setName(rs.getString(1));
e.setRoll(rs.getString(2));
list.add(e);
}
return list;
}
});
}
}
2.Student.java:
public class Student {
private String name;
private String roll;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getRoll() {
return roll;
}
public void setRoll(String roll) {
this.roll = roll;
}
public void display(){
System.out.println("Name: "+name+" Roll="+roll);
}
}

}
The jars that i included in reference library:
These are the jars i included
Kindly help me in this regards.A prevalentines day thank you is in advance.

Answer 1

The relevant part of your errormessage is:
java.lang.IllegalStateException: Could not load JDBC driver class [com.mysql.jdbc.Driver]
You can download that jar from here: 5.1.38, or look for different versions on the central nexus repository.
Note: you would be much better of employing some dependency management system, rather than doing this manually. I suggest taking a look at Maven.
