you can not set anything in a request similar to ServletRequest.setAttribute.
Request attributes on the server side are kept in memory and accessed as
Java objects. Whatever you put into an HTTP request needs to be sent over
a connection to the server, and as such you have to indicate where in the
request it should be put and what transformation/encoding to use. The two
concepts are really completely different.

Have a look at the MultipartRequestEntity and the PartSource interface.
You can feed your byte array in as a ByteArrayInputStream with an empty
or invented filename.

hope that helps,
