@Mohammad Have a look at the code in “Quick Bit Notes” which is on Google code.

It’s pretty small and includes Restlets that access the GAE datastore.

You need to define the ImageFile class and of course populate it with the image data. I use the following class:

public class ImageFile implements Serializable { private byte[] content; private String filename; private String mimeType;


    public ImageFile(byte[] content, String filename, String mimeType) {

        this.content = content;

        this.filename = filename;

        this.mimeType = mimeType;

    }
    public byte[] getContent() {

        return content;

    }
    public String getFilename() {

        return filename;

    }

public String getMimeType() { return mimeType; } }
