I should also mention that, if you really *do* want to get your hands
dirty with MBR/MBW implementations, the jersey-multipart source code
itself includes such implementations for the MultiPart class. If you
check out the source tree of the Jersey subversion repository, check out
the following files:
*
contribs/jersey-multipart/src/main/java/com/sun/jersey/multipart/impl/MultiPartWriter.java
*
contribs/jersey-multipart/src/main/java/com/sun/jersey/multipart/impl/MultiPartReader.java
The first class is used when writing out a MultiPart instance into the
"multipart/mixed" (or whatever) format that corresponds to the
standard. There's a bit of trickery inside that reuses the standard
Jersey providers for each body part (so that the multipart can contain
any media type that Jersey already has support for). The second class
is used at the opposite end, to convert the byte stream of the incoming
message back in to a MultiPart instance with appropriate BodyPart children.
The fact that Jersey gave me the capability to do this (and not have to
go reinvent a translation mechanism for all the body parts) is *way*
cool ... props to Paul and the Jersey team for making it possible.
