Well, I give up for now. So far I can't get the bytes by fetching them fast enough and the FileReadChannel won't read all the bytes. I've run out of time and ideas for today. I have an ugly hack going on which will allow me to move on for now, but it bugs me :). I guess my ultimate goal of reading image bytes, one to get the dimensions then to resize/scale it down is my goal. For me, this has been a real challenge with the 1.4.3 api, but I see progressive trend of improvements by the GAE devs, so I am looking forward to the future releases.

Yes. Stick the int var in your class with @Persistent. @Persistent private int myInt; http://code.google.com/appengine/docs/java/datastore/entities.html#Properties_and_Value_Types Casting from long to int should not throw anything I'm aware of. It might truncate a number into int. long test = 1234; int myInt; myInt = (int) test; should not throw.

[appengine-java] Re: jdo update is inserting when I don't want it to
pm.makePersistent( persistme ); is called after the deletion it will recreate it. You'll have to query it by objectid first and see if it exists. If it exists you could update. SQL would need an ID to update, but in JDO, it will make a new ID on insert and update depending on existence. like so: MyClassJdo exists = pm.getObjectById(MyClassJdo.class, keyId); Brandon Donnelson http://gwt-examples.googlecode.com -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: Timeout when trying to upload to Blobstore (files < 5k)
Hmmm, I can't see anything obvious. I know this can be be a bear b/c I've done it too. 10 seconds is all you got, unless you move to a task. Although, it will allow you to load any size file to the store, but after its loaded you got 10 seconds to do processing. It shouldn't hang. Can you find the file in the blobstore after running above and before you think it hangs? It should be before you hit the upload servlet? http://code.google.com/p/gwt-examples/wiki/DemoGAEMultiFileBlobUpload - here are some more notes I put together on blob stuff http://code.google.com/p/gwt-examples/wiki/gwt_hmtl5#Upload_Canvas_Image - another thing I do to upload Brandon Donnelson http://gwt-examples.googlecode.com -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: Performance of blobstore upload API vs the new files api
I've done them all and don't see any difference in the apis. The File api has a few bugs and is experimental, at least I think thats the one your talking about. I prefer the HTML post method b/c its well defined, and there are libs available to put together a post. Its a multistep process, one to get the blob url, which is very fast and then post and wait for upload. I figure either road you take same steps different way. Some more notes with demos.

Re: [appengine-java] Re: when will BigDecimal be supported in datastore?
I would have to agree, BigDecimal would be nice in the app engine. Storing as a String presents the sorting challenge. Double, Float, Long just won't work for money and latitude and longitude. And money has to do with everything. App Engine is storing phone numbers, ratings, and other objects, why not BigDecimal? Even the geo points need more precision. Geocoding spits out a double, and App Engine wants a float, that won't work either. BigDecimal is what geocoded coordinates should go into. Basically a String, with numeric sorting I think?

[appengine-java] Suggestiong New Feature: Add Geocoding Maps API service to the Quota System on App Engine
I'm suggesting adding the Maps Api Geocoding as a service in App Engine. Why: 1. I don't have 10,000+ for the maps API premier and I am hitting below 2500 request per day. 2. I hit the OVER_QUERY_LIMIT on batch request. On multiple batch request for geocoding and I am under 2500 request per day. (this only happens from appspot and not from 127.0.0.1) I'd like to use the service and pay as you go like the app engine format?

[appengine-java] ImagesServiceFactory.makeImageFromBlob(blobKey) > image.getImageData() > gets NULL error >
When trying to get image byte data I get null using this method: (any
thoughts?)
Image image = ImagesServiceFactory.makeImageFromBlob(blobKey);
Byte[] bytes = image.getImageData(); // this doesn't work as expected.
It would be nice to fix that method to give whats expected. In my opinion
the image api is thin and could use some enhancements to make it more
useable. I'd like to see it become more like image magick api or GD2 linux
api. Also to note, I'd like to see it have a method to stick the image into
a the blob store with a method call.
My Work around:
private byte[] getImageBytes(BlobData blobData) {
long endIndex = 1024;
long startIndex = 0;
BlobKey blobKey = new BlobKey(blobData.getKey());
ByteArrayOutputStream stream = new ByteArrayOutputStream();
if (endIndex > blobData.getSize()) {
endIndex = blobData.getSize();
}
while (endIndex <= blobData.getSize()) {
byte[] b = blobstoreService.fetchData(blobKey, startIndex, endIndex);
try {
stream.write(b);
} catch (IOException e) {
e.printStackTrace();
}
startIndex = startIndex + 1024;
endIndex = endIndex + 1024;
if (endIndex > blobData.getSize()) {
endIndex = blobData.getSize();
}
if (startIndex > endIndex) {
break;
}
}
byte[] r = stream.toByteArray();
return r;
}

[appengine-java] Re: GAE response returns null randomly
10 seconds is the limit from what I read. I use a task for anything that takes over 10 seconds. Setup a servlet to init the task. The task then will start your methods, then you have up to 10 minutes to do the task before starting another task. You can use another rpc call to watch for the task completing before getting what you need, although you'll need to pass some stuff to JDO store to do this, which is another topic.

[appengine-java] Re: ImagesServiceFactory.makeImageFromBlob(blobKey) > image.getImageData() > gets NULL error >
The image service has limitations. It won't allow to resize a width thats > 4000px. The image service is for light duty small images. The current cameras on the market are producing very large images and scaling them is trouble some. I have panoramic images, where the widths are gigantic and this image service isn't cutting it. I suggest adding some beaf to the image service please :). I would think that this is a core function that spans most applications, and more beaf to it would conserve resources with the shared libraries across the entire app base. Besides, I am having to jump through lots of hoops to get this stuff to work, which is very boxy! Anybody use a library jar to do the job?

Tiling an image, (mapping it) is a challenge with a percentage, due to precision, or my perceived precision of division of the image. I figured out a work around I think using different math to divide it up to have a precise division that so no overlapping occurs. But to my point, I believe using a make crop with pixels would be nice.

Its pretty easy to store the blobkey in the datastore with the parameters needed to find the blob in the blobstore, all you then need is that blobkey, and serve it from the blobstore, and the only latency you get is for the session loading if one is not loaded.

[appengine-java] Re: DDL - move from boolean to String
Are you asking if you can change/morph your datastore values from Boolean to String? If so, you'll have to make a copy so the new property is added in older records. Or do a conversion when getting a record. You can add a persistance variable at any time, and the property going forward will be added to the record. To deal with previous records that have nothing null stored, then add logic to check for that. When I make adjustments to the datastore persistance classes, I increment my version before deployment. I've run across errors deploying the same version with new datastore enhancements with new class variables.

side of app engine. Is there a work around or am I missing something?
private String getRequest_Image(String fileName, String contentType, String
file) {
String s = "";
s += "Content-Disposition: form-data; name=\"File\"; filename=\"" +
fileName + "\"\r\n";
s += "Content-Transfer-Encoding: base64 \r\n";
s += "Content-Type: " + contentType + "\r\n\r\n"; //
s += file;
s += "\r\n";
return s;
}

[appengine-java] Re: problems with JDOQL query
I do know that calling it once works kinda like this. I never use
declarations in my code so I don't know if this works.
query.setFilter( "password == passwordParam && username == usernameParam &&
active == activeParam" );
But I do know setting a filter works like this:
query.setFilter( "password == \"" + passwordParam + "\" && username == \"" +
usernameParam + \" && active == \"" + activeParam + "\"" );
1. numeric types do not need quotes
2. ancestors and other object types are a bit different.
3. to debug, pause on the query object, it looks simliar to sql.
Here is a snippet from one of my query methods I use to get the data for GWT
RPC transport. There are many ways to do it:
public ThingStuffData[] query(ThingStuffDataFilter filter) {
if (filter == null) {
log.severe("ERROR: ThingStuffJdo.query() Set a filter");
return null;
}
String qfilter = filter.getFilter();
System.out.println("ThingStuffJdo.query(): filter: " + qfilter);
// nullify
queryThingStuffJdo = new ArrayList();
PersistenceManager pm = sp.getPersistenceManager();
try {
Query q = pm.newQuery("select stuffIdKey from " +
ThingStuffJdo.class.getName());
q.setFilter(qfilter);
q.setRange(filter.getRangeStart(), filter.getRangeFinish());
List ids = (List) q.execute();
Iterator iter = ids.iterator();
while (iter.hasNext()) {
Key key = (Key) iter.next();
queryKey(key);
}
q.closeAll();
} catch (Exception e) {
e.printStackTrace();
log.log(Level.SEVERE, "", e);
} finally {
pm.close();
}
// work in null if need be
if (queryThingStuffJdo == null || queryThingStuffJdo.size() == 0) {
return null;
}
// convert to object array
ThingStuffJdo[] tsj = new ThingStuffJdo[queryThingStuffJdo.size()];
if (queryThingStuffJdo.size() > 0) {
tsj = new ThingStuffJdo[queryThingStuffJdo.size()];
queryThingStuffJdo.toArray(tsj);
}
// convert for transport to client
List tjsa_list = Arrays.asList(tsj);
ThingStuffData[] tsd = convert(tjsa_list);
return tsd;
}
