Re: [appengine-java] Mutation pool bug?

2011-01-15 Thread Stephen Johnson 
Do you have this defined in your mapper class?

@Override

public void taskCleanup(Context context) {

try {

// make sure to call super classes taskCleanup so that the
DatastoreMutationPool

// gets flushed properly otherwise puts/deletes can be lost;

super.taskCleanup(context);

} catch (Exception ex) {

log.severe(ex.toString());

}

}

Re: [appengine-java] Custom location for local_db.bin?

2011-01-15 Thread A. Stevko 
Why not just back it up or check-in to version control?
Another option is to use ln -s to move it.

[appengine-java] Custom location for local_db.bin?

2011-01-15 Thread Daniel Kvasnicka jr. 
Hey,

is it possible to customize the location of local_db.bin? I need it to be 
somewhere outside the application, so that it doesn't get harmed.
I'm using NetBeans to develop apps and Clean & Build always destroys my 
data.
There must be some option for this, e.g. in appengine-web.xml, right?

There's another function executeWithArray on the query object that you

[appengine-java] Instead transparency I get black

2011-01-15 Thread Christian Reiter 
Hi,

if i use the image service there seem to be some problems with transparency.

I tried to comibe two pictures. the first one without any transparency 
information and the second with some.
The picture with transparency is this 
one
:

some parts are complete white and some are transparent white. But what i get 
is the following:





which obviously does not using transparency for combining the two pictures. 
There seems to be a black background behind the picture with the 
transparency.












code looks like this:
private byte[] createThumbnail(String path, int width, int height) throws 
IOException
{
/* some missing parts*/
 
 Image thumbnail = imagesService.applyTransform(crop, oldImage, 
ImagesService.OutputEncoding.PNG);
 
 // create overlay
 Composite th = ImagesServiceFactory.makeComposite(thumbnail, 0, 0, 
1.0f, Anchor.TOP_LEFT); // TODO: check if online works with transparency
 Composite ov = ImagesServiceFactory.makeComposite(overlay, 0, 0, 1.0f, 
Anchor.TOP_LEFT);
 LinkedList finalImage = new LinkedList();
 
 finalImage.push(ov);
 finalImage.push(th);
 
 thumbnail = imagesService.composite(finalImage,THUMBNAIL_WITH, 
THUMBNAIL_HEIGHT,0,ImagesService.OutputEncoding.PNG);
 
 return thumbnail.getImageData();
}

first i get the first pictures, which is in .jpg format, crop it and 
transform to .png. Then i try to stack the overlay with some transparency on 
it. 

Have you any ideas what causes the problem and/or have an idea how to work 
around this?

thanks

[appengine-java] Re: Error while trying uploading an image on live server

2011-01-15 Thread Christian Reiter 
I think i no got the error. The request seemed to be incorrect because of 
the two write(baos, "--"+boundary+"\r\n");

Now it seems to work properly.
