Setting the content type to "text/html" is inconsistent with the data you are
actually sending -- a binary stream of serialized Java objects. Normally,
"application/octet-stream" or something like that is used for serialized Java
objects.

What kind of client program is submitting the request to get this data? If it
is a browser, you're going to be out of luck -- browsers have no clue how to
understand serialized Java objects. Only Java applets or client applications
can do that.
If you want to generate an HTML page displaying your output, you should be
writing HTML, not serialized Java objects.
