There is the sun.misc.BASE64Encoder but it's undocumented and Sun recommends against using any classes in the sun.* package.
http://java.sun.com/products/jdk/faq/faq-sun-packages.html

Googling on 'sun.misc.BASE64Encoder' will yield both alternatives and, in some cases, the actual code to roll your own.

As for getting the post to begin with, look at the getInputStream method of the ServletRequest interface:

You can read the binary contents of your file without base64 by setting the mime type in the form as multipart/form-data and read the contents in the servlets.

This is how file-uploads and email attachments work in web-based applications. I am not sure if they are precisely applicable to your requirements.
