I was even thinking a bit more direct for read operations:

MyJaxb jaxb = parts.get(0,MyJaxb.class);

This variation seems to work out the best in my tests so far. I've  
gotten the basic reader details functioning, but it'll require more  
parts as we'll need our own Multipart and BodyPart classes. But it  
should be much more flexible than having the developer have to parse  
each part themselves.

I tried a variation on this whereby you'd have:

void post(@MimePart(0) String partOne, @MimePart(1) MyJAX object) {...

This still has the same limitations as you pointed out, but it's a bit  
more akin to @QueryParam, etc. The problem is that reading the data  
for the 2nd part was always failing. As of now, a JavaMail multipart  
provider has already.
