How to set the id value for Student in delete()? [closed]

Answer 1

Use the action field to set the parameter id:

public class StudentAction extends ActionSupport {

    private List studentList;
    Student student;
    StudentDAO sdo = new StudentDAO();
     private Long id;
    //getter and setter


    public String delete() {
        System.out.println("delete action");
        System.out.println(getId()); 

        sdo.delete(getId());

        return SUCCESS;
    }
}

One more thing if you want to implement ModelDriven you should add the code for your model

private Student model = new Student();

public Object getModel() {
  return model;
}

The code is like in the documentation example.
