I'm trying to update a simple boolean value on a collection of objects
returned by a query. The objects are being returned, and I set the
value on the bean, then persist, but it's not working. What am I
missing?
The Submission class has a "notifyAfter" as a Long (raw date), and an
"isNotified" Boolean.
public void notifySubmissions( ){
PersistenceManager pm = pmf.getPersistenceManager();
Long rawDate = new Date().getTime() ;
Query query = pm.newQuery(Submission.class);
query.setFilter("rawDate >= notifyAfter && isNotified == false");
query.declareParameters("Long rawDateParam");
try {
List<Submission> results = (List<Submission>)
query.execute( rawDate);
if ( results.size() > 0 ) {
log.info(" " + results.size() + " results found");
Properties props = new Properties();
Session session = Session.getDefaultInstance(props,
null);
for (Submission s : results) {
log.info("Emailing: " + s.getEmail());
Boolean mailed = true;
try {
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("...",
"...") );
msg.setText( ... );
msg.addRecipient(Message.RecipientType.TO,
new
InternetAddress(s.getEmail()));
msg.setSubject("... Notification");
Transport.send(msg);
log.info("Mail sent to: " + s.getEmail());
} catch (AddressException ae) {
log.warning( ae.getMessage() );
mailed = false;
} catch (Exception e2) {
mailed = false;
log.warning( e2.getMessage() );
}
if (mailed){
s.setIsNotified(true);
pm.makePersistent( s );
}
}
} else {
log.info("No results found");
}
} finally {
query.closeAll();
}
}
