Encode your document in 64 bits (e.g., 
http://www.erlang.org/doc/man/base64.html) and slice it where you think 
it's optimal. For JAVA, I don't remember if there is or not such 
encoding. Nevertheless, the idea is used in messaging (and not only), 
where large quantity of data (e.g., file transfer in between users) is 
transfered.
