[Building Sakai] Returning binary data (pdf) from Entity Provider?

[Steve Swinsburg]

Hi Curtis,

This is from the ProfileEntityProvider which returns the binary of an image:

final byte[] bytes = image.getBinary();
if(bytes != null && bytes.length > 0) {
	try {
		out.write(bytes);
		ActionReturn actionReturn = new ActionReturn("BASE64", image.getMimeType(), out);
		return actionReturn;
	} catch (IOException e) {
		throw new EntityException("Error retrieving profile image for " + ref.getId() + " : " + e.getMessage(), ref.getReference());
	}
}

Also, in your example, you have the output being sent as text/plain so change that to application/pdf.

cheers,
Steve
