I'm doing the "Getting Started" tutorial for the Google Web Toolkit
with App Engine, called "StockWatcher". This tutorial right here:
http://code.google.com/webtoolkit/doc/latest/tutorial/appengine.html
I finished writing the whole code, and deployed to GAE. But got an
error and found this DatastoreNeedIndexException on the log:
javax.servlet.ServletContext log: Exception while dispatching incoming
RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service
method 'public abstract java.lang.String[]
com.google.gwt.sample.stockwatcher.client.StockService.getStocks()
throws com.google.gwt.sample.stockwatcher.client.NotLoggedInException'
threw an unexpected exception:
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found.. <datastore-index kind="Stock" ancestor="false"
source="manual"> <property name="user" direction="asc"/> <property
name="createDate" direction="asc"/> </datastore-index>
The culprit is this method:
public String[] getStocks() throws NotLoggedInException {
checkLoggedIn();
PersistenceManager pm = getPersistenceManager();
List<String> symbols = new ArrayList<String>();
try {
Query q = pm.newQuery(Stock.class, "user == u");
q.declareParameters("com.google.appengine.api.users.User u");
q.setOrdering("createDate");
List<Stock> stocks = (List<Stock>) q.execute(getUser());
for (Stock stock : stocks) {
symbols.add(stock.getSymbol());
}
} finally {
pm.close();
}
return (String[]) symbols.toArray(new String[0]);
}
I don't understand what's wrong. Why is the index not matching and how
could I fix it? Is the tutorial wrong or did I screw up somewhere?
If it helps, here's the deployed app:
http://vib-test-01.appspot.com/
and here's the full source code if anyone cares:

Thanks in advance.
