Hi,
I have groovy script that read an image from a Blob field, and write
it to the response. It runs well on my local environment, but causes
java.security.AccessControlException on the google app engine.
Any idea why it happened and how to fix it?
The script (image.groovy) looks like this:
import com.google.appengine.api.datastore.*
import com.google.appengine.api.images.*
def k = KeyFactory.stringToKey( params.key )
def img = datastore.get(k).content.getBytes();
if ( img ){
def width = params.width;
def height = params.height;
if ( width && height ){
Image oldImage = ImagesServiceFactory.makeImage(img);
Transform resize =
ImagesServiceFactory.makeResize(width.toInteger(),
height.toInteger());
Image newImage = images.applyTransform(resize,
oldImage);
img = newImage.getImageData();
}
response.getOutputStream().write(img)
}else{
println "failed to find img"
}
And the error:
