[taglibs] Iterating over a Hashtable

[Garrett Smith]

Hey,
Having a problem iterating over a Hashtable. The iterator is getting the next entry set in the hashtable. Instead, I want to get the values.
Enough blabbering. Here's the code:

<c:forEach var='user' items='${applicationScope.users}'>
<c:out value="${user.username}"/>
</c:forEach>

<h2>With Scriptlet</h2>
<%
  Hashtable users = (Hashtable)application.getAttribute("users");
  if(users != null && users.size() > 0){

  for(Enumeration e = users.elements() ; e.hasMoreElements() ;) {
    User user = (User)e.nextElement();
%>
  <ul>
    <li><%= user.getUsername() %></li>
  </ul>
<%
  }
}
%>

You see the first one will cause an error but the second one, a scriptlet works (when the first one is omitted).

javax.servlet.ServletException: An error occurred while evaluating custom action attribute "value" with value "${user.username}": Unable to find a value for "username" in object of class "java.util.Hashtable$Entry" using operator "." (null)

Well noone answered this so I will.

<c:forEach var='users' items='${applicationScope.users}'>
  <c:out value="${users.class}"/>
</c:forEach>

Prints: class java.util.Hashtable$Entry
So now I now exactly which class I'm dealing with: Map.Entry.

<c:forEach var='users' items='${applicationScope.users}'>
  <c:out value="${users.value.username}"/>
</c:forEach>

Prints: jgirl-a******** (self-censorship, here--you figure it out.)
Explanation:
users -- Map.entry
users.value -- [com.dhtmlkitchen.User]
users.value.username -- jgirl-a******** (from getUsername())
I wonder how this converts users.value to a com.dhtmlkitchen.User. users.value should be a java.lang.Object. I didn't cast anything. Tag magic...
