Multipart problems

[Incze Lajos <in...@mail.matav.hu>]

Something really went wrong in the multipart request handling
(manipulation).

The only scenario that works at the moment for me, when the
file and the other request parameters all are good, so the
file upload was successful. I'm testing with tomcat3.3 and
tomcat4 (m3 and b5 versions) and the struts b3 version.

When something is wrong the multipart handlibg manipulates
something dirty (rewraps/repackages? the request) and there
is a problem here.

Tomcat3 and Tomcat4 fails differently but that's sensible.

E.g. the log shows this when the filename and upload was ok
but the ActionForm validation routine retuned an error (tomcat4b5,
struts1b3):
