JBoss 4.0.1 & multipart [was Re: multipart forms & file upload]

[Erik Gustavson <go...@gmail.com>]

So I haven't found a smoking gun just yet. I've gotten rid of tiles
but that didn't help. I've moved back to JDK 1.4.2 to double-check,
that did not change anything.

As far as I can tell, when I use a form with
enctype="multipart/form-data" under JBoss 4.0.1sp1 no ParameterMap
makes it through down into the LifeCycle. JBoss is using Tomcat/5.0.28
as its servlet engine. Regular forms work perfectly fine.

Does anyone have any ideas?
