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

[Aaron Zeckoski]

You can always get the response and set things on it directly if you
like but the more automatic way would be to use the OutputStream to
dump the content and use the ActionReturn to set the headers and
content type.
actionReturn.encoding and actionReturn.mimeType must be set or it will
try to guess the mimetype itself based on really simple rules that
means it will assume JSON most of the time.
