Hi,
I've been successfully building my project each day. Today I come to
it and attempt to start it in the debugger when I get the above
error. Here is some of the stack trace:
----

So, it's when compiling the JSP. I don't know if it's when resolving
the tag or the jsp that it encounters this "unknown", but no matter -
neither has been changed(!) since it was compiling just fine. Also, I
can see the appengine-api jar on the build path (as it was from when
the project was setup under Eclipse).
Here's an extract from the JSP:
----
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page import="java.util.List" %>
<%@ page import="com.google.appengine.api.users.User" %>
<%@ page import="com.google.appengine.api.users.UserService" %>
<%@ page import="com.google.appengine.api.users.UserServiceFactory" %>
<%@ page import="com.google.appengine.api.datastore.Key" %>
<%@ taglib uri="/WEB-INF/kickboxking.tld" prefix="kbk" %>
<html>
<body>
<div id="header">
<%
UserService userService = UserServiceFactory.getUserService();
if (session.getAttribute("activePlayerId") != null) {
%>
<kbk:playerName key="<%=
(Key)session.getAttribute("activePlayerId") %>"/>! (You can
<a href="signOut.jsp">sign out</a>.)</p>
</div>
...

It's falling over on that <kbk:playerName....> tag!!!! Pure bit-rot
as it was fine when I was running it yesterday :-(
