Ava Web Service, Help me please with this really simple project

Question

Hi,
I', using Tomcat 557 jdk 1.5.0.0_01, axis 1.2, and i have to build simple web service. The project is a list of students (their name, surname) and it has to do as the following:
-adding new student
-deleting existing student
-changing existing student (not a must)
-dispaying all students list
-searching student by id
And it has to operate with simple text file (the database is too complicated in my situation)
In C:\Java\jakarta-tomcat-5.5.7\webapps\axis i have student.jws file:
import java.util.*;
public class students{
                private Map dane = new TreeMap();
     public students() {
          dane.put(new Integer(1), new Students("Adam", "Alt"));
          dane.put(new Integer(2), new Students("Claudia", "Shift"));
     dane.put(new Integer(4), new Students("Gregor", "Tab"));
          dane.put(new Integer(3), new Students("Robert", "Enter"));
     public void new(String name, String surname){
     public int[] list() {
          Set klucze = dane.keySet();
          int[] list = new int[klucze.size()];
          int i = 0;
          for (Iterator it = klucze.iterator(); it.hasNext(); ) {
               list[i++] = ((Integer) it.next()).intValue();
          return list;
     public Student student (int nr) {
          Student u = (Student ) dane.get(new Integer(nr));
          return u;
}And in C:\Java\jakarta-tomcat-5.5.7\webapps\axis\WEB-INF\classes i have the Student.java file:
public class Student{
     private String name;
     private String surname;
     public Student() {
     public Student(String name, String surname) {
          this.name= name;
          this.surname= surname;
     public String getName() {
          return name;
     public void setName(String name) {
          this.name= name;
     public String getSurname() {
          return surname;
     public void setSurname(String surname) {
          this.surname= surname;
}And in IE http://localhost:8080/axis/students.jws?method=list
Shows the list of students.
The thing is, that it should work with at least simple text file (i don't even know the methods for connecting the database) and it should do the things, that i've already mentioned:
-adding new student
-deleting existing student
-changing existing student (not a must)
-dispaying all students list
-searching student by id
Could somebody add some code to this simple service? I know, that for you it's not any problem, you know java and it's a matter of life and death for me. Only if somebody help me, i will be able to finish current year of my studies. Normally i don't ask for such things, but now i don't have any choice - i have very important exam on monday, and i also have to present this project in this day.[/code

Answer 1

And in IE http://localhost:8080/axis/students.jws?method=list
