Re: enctype="multipart/form-data" forms

Hi,

I think you should add

  <%@ page language="java" contentType="text/html; charset=utf-8" %>

at the absolute top of your page. And if that does not help, maybe

  <% response.setContentType("text/html; charset=utf-8"); %>

will help, but i think you won't need that last one.

You should take a look at e.g. the 'basic' jsp editors, which IIRC also
post multipart/form-data and
using them it should work fine. If that does work, I suggest you imitate 
them..

I took /mmexamples/taglib/upload.jsp and added a text input field 'title'.
Then after upload I use this field as input for the title for the
attachment. see below

The issue is rather complicated. IIUC, you should assume that the
characters are received encoded 
 according to the same encoding as the page which did the post.

You could also use the CharacterEncodingFilter to add a encoding to the
request, but I don' think it 
 is essential.

You might also be hit by bug #6569, but I have not the faintest idea how
your implementation does 
 look like.

You should take a look at e.g. the 'basic' jsp editors, which IIRC also
post multipart/form-data and
using them it should work fine. If that does work, I suggest you imitate
them.. 

 Anyhow, the problem is not the 'enctype'.
