Hi, I got the following exception in a method executing a query:
C 07-05 07:23PM 42.069
Uncaught exception from servlet
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found.

com.solveware.gwt.sample.stockwatcher.server.HistoricalQuote.getAllQuotesOnSymbol
(HistoricalQuote.java:130)
...
However, according to the admin console, the required index is up and
running
HistoricalQuote
id ▲ , symbol ▲ , date ▲ Serving
And the code for executing the query:
public static List<HistoricalQuote> getAllQuotesOnSymbol(String
symbol) {
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(HistoricalQuote.class);
query.setFilter("symbol == userSubmittedSymbol");
query.setOrdering("date ASC");
query.declareParameters("String userSubmittedSymbol");
List<HistoricalQuote> entries = (List<HistoricalQuote>)
query.execute(symbol);
return entries;
}
So I wonder if anyone can shed some light on why this is happening?
Is it a problem on the GAE side that is waiting to be fixed?
Any help is appreciated. Thanks.
Best,
Tommy
