RE: SOLVED invalid multipart request in beta 3 Controller Wrapping Request

[Peter Doyle <pe...@teomedia.com>]

HAHA!

Right for anyone (not many) who came across this problem here is how to
solve it.

In the struts upload application you will see that control is sent to a JSP
after the uploading. If you send it to another action you get the
MultipartIterator problem. This is *I think* because the request is wrapped
in a MultipartRequest, as of beta 2. Now the action you forward to does not
expect the multipart request, I think, so it causes the exception... I guess
you could change the encrypt type of the destination action... anyway

What I did was forward control to a JSP that only contains a
<logic:redirect> to the action I want it to go to in the first place. As I'm
dumping everything into session anyway I don't need to worry about
replicating the request query.
The redirect jsp is rendered and control is redirected. You don't even know
its there.

The reason I don't use multipart in my original action is its not designed
to use multipart. I do the uploading in a separate form and action (that is
multipart) and then go back to the original action with the result, not to a
jsp.

Well it works for me :)

Request


Hi,
 I'm using IE 6 beta. I tired it with Netscape 6 and there was no change.
Its not a browser issue. The struts upload example works I think because the
forward is to a jsp and not to another action. In my case I forward to an
action that takes in the request from the controller. I guess the request is
Multipart but should be a regualar request....or the other way around.. Its
just confusing.

At least I'm not alone :)

Are you using IE 5.5?  Coz there are some documented issues with IE5 and
below and file uploads in Struts.

Unfortunately I AM using IE5.5 and this is not working for me in Struts
1.0b3 where it was in Struts 1.0b1 so something has definitely been broken
in either b2 or b3.
