getRequestDispatcher("/viewstudent.jsp?students="+studentList);

And on jsp just accept the value from the get method, e.g

List<Student> studentList = (List<Student>)request.getParameter("students")

Print it out like this;

<%for(int i = 0; i<student.size();i++){ out.print(sutudent.getName()); }

Just like that. The main point is passing the arrayList into the parameter of the link.
