html:select and html:options simple question - please help

Question

Hi Friends,
I am having a problem, please help me .I want to run a query and display all the lastnames of all the users in my database.Here are my files:
UserForm.java
public class UserForm extends ActionForm{
     private name firstName;
     private name lastName;
     //all getter and setters
viewuser.jsp
<html:select property="lastName">
    <html:options collection="users" property="lastName" labelProperty="lastName" />
</html:select>
and my Java Utility class method
public ArrayList getusers() throws Exception {
         ArrayList aList = new ArrayList();     
          Connection con = ConnectionUtil.getConnection();
          PreparedStatement stmt = null;
          try {
               stmt = con.prepareStatement("select last_name from USERS);     
               ResultSet rs = stmt.executeQuery();
                  if (rs.next()) {
                      aList.add(rs.getString(1));
                  }else {
                       return null;
                  rs.close();
                  return aList;
          } catch (SQLException e) {
               e.printStackTrace();
               throw new ServiceProcessingException(e.getMessage());
          } finally {
               ConnectionUtil.closeStatement(stmt);
               ConnectionUtil.closeConnection(con);
     }My problem is what i need to do in my Action class,so that it sets the "users" variable
properly and i would be able to read that variable in my jsp and display the lastname
of all the users.I am tryin this but failing badly:
public class UserAction extends Action{
  ArrayList userssList = Utility_class_obj.getUsers();
  request.getSession().getServletContext().setAttribute("users", usersList);Please Please help,I would really appreciate your help.
Thanks

Thanks a lot friend...this time i made it work my style,next time i will use tha mehod.But I think I am not doing it the right way,please correct me:
This is the method in my utility class where i run the query and I doubt I am not doing it right here:
PreparedStatement stmt = null;
ViewForm vForm = null;
try {
stmt = con.prepareStatement("SELECT LAST_NAME FROM   USERS_ADD");     \
ResultSet rs = stmt.executeQuery();          
while(rs.next()) {
       vForm = new ViewForm(rs.getString(1));          
      aList.add(vForm);          
   rs.close();
   return aList;          }
}And I made this constructor in my viewForm class:
public ViewForm(String lastName){          this.setLastName(lastName);     }I do this in my Action class then:
ArrayList pList = csDAO.getUsers();  
     if(pList  != null){         
     request.getSession().getServletContext().setAttribute("plist", pList);      
}And finally this in my jsp:
    <html:select property="lastName"> 
    <html: options collection="plist" property="lastName" labelProperty="lastName" /> And it works,but i don't think I can keep adding constructors to my form class like that,and moreoever if I want to search by first name ,there would be a conflict between 2 constructors,so can someone please tell me the right way to do this.
Thanks
