Subject: [Beepcore-java-users] RFC 822 Header Parsing broken; Patch

Hi,
In an attempt to implement Beep as a protocol for JAXM and SAAJ using the
SOAP Profile specification, I noticed, that the implementation of the
RFC822 Header parser has not been complete.

The problems arises when sending attachments with SUNs default
implementation of JAXM. When sending an Attachment with Soap, the payload
actually contains a full mime multipart document, so one mime header
of a beep message contains the boundary which happens to be on a new line
with the SUN implementation; something like:

  Content-Type:multipart/related; type="text/xml";
             boundary="----=_Part_0_19610963.1069622873839"

This is correct according to RFC822 (Paragraph 3.2, field-body
production), but is not implemented in the Beep header parser which does
not understand multiline headers. So in this case the boundary is lost and
SOAP-Attachments won't work :-(

I fixed this for the current CVS by implementing a RFC822 parser (an
improved version found on w3c)

The patch can be found at:

http://jwsbuch.net/~hzeller/beep-rfc822-headerpatch.tar.gz

It will create a new java file and a patch file:

  rfc822-header-parse.patch
  src/org/beepcore/beep/util/Rfc822HeaderParser.java

The files can then be patched with
  patch -p0 < rfc822-header-parse.patch

With this patch, sending JAXM Attachments works without problems.

ciao,
 -hen

PS:
My JAXM-Implementation is just proof of concept and far from ready, but
anyone who wants to have a look:
  http://jwsbuch.net/~hzeller/jaxmbeep-0.0.1.tar.gz
The implementation was quite simple. Look in example/SimpleBeepServer.java
how easy it will become to implement a JAXM ReqRespListener. It actually
is that simple!
