Trying to verify a user, but my check functions don't works

Posted 04 March 2012 - 03:38 AM

I am starting to learn using JSF and Beans, but I am having a problem, with my verify method, my verify code is like this:
public String verifyUser2(){
	   ArrayList<User> users = new ArrayList<User>(service.getUsers());
	   String dir ="error";
	   boolean found = false;
	   int i = 0;
	   
	   while(!found && i < users.size()){
		   User u = users.get(i);
		   System.out.print(u.getName());
		   System.out.print(u.getPassword());
		   
		   System.out.println(name);
		   System.out.println(password);
		   
		   if(u.getName().equals(name) && u.getPassword().equals(password)){
			   found = true;
			   dir="welcome";
		   }
		   else{
			   i++;
		   }
	   }
	   System.out.println(found);
	   
	   return dir;
	   
   }


And the way I call it is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html">
   <h:head>
      <title>#{msgs.title}</title>
   </h:head>
   <h:body>
      <h:form>
         <h3>#{msgs.heading}</h3>   
         <table>
            <tr>
               <td>#{msgs.hName}</td>
               <td><h:inputText value="#{userBean.name}"/></td>
            </tr>
            <tr>
               <td>#{msgs.hPassword}</td>
               <td><h:inputSecret value="#{userBean.password}"/></td>
            </tr>
         </table>
         <p><h:commandButton value="#{msgs.login}" action="#{userBean.verifyUser2}"/></p>
      </h:form>
   </h:body>
</html>


But for some reason I newer find the user and I use the sysout's to check if the username and password is the correct once and from what I can se I do type in the correct one. Can anyone tell me why I never get true returned. Am I calling something wrong or what?
Pleas tell if you need more of my code

i think you should query for only specific user that being typed in login form, not all of them. so the method should be service.getUsers(String _userId) or something like that.

//find only user typed in login form
ArrayList<User> users = new ArrayList<User>(service.getUsers("XYZ"));

for( int i=0; i<users .size(); i++ ) {    
     User u = (User) users.get(i);
}

if(u.getUserId().equals(loginForm.getUserId())){
     //do authenticate password
}


hopefuly that help, if not try visit this link, there is a authenticate() method there, you could learn more there

cheers :gun_bandana:
