Hi Art,
Jersey does not provide message body workers for java.awt.Image class
out of the box. You can get access to the message body input stream,
or get it (the message body) written into a temporary file and process
it from there, e.g.:
File imgFile = wr.accept("image/*").get(File.class);
Image image = ImageIO.read(imgFile);
After you fix this, you will get similar problem, when
trying to return the Image instance out from your resource method.
This time, you will be getting a missing message body writer error.
And again, you can return an OutputStream/File instead of the Image
to fix this.
Another approach would be, if you wish to make your original code
work intact, to implement your custom java.awt.Image message
body workers. Please see the entity-provider example [1]
for reference.
HTH,
~Jakub
