Re: uploading files from a jsr168 portlet

[John West]

It's been a while since I did this, but if I remember correctly you need 
to parse each part of the request separately to find the find content. 
It's easier to use a pre-made class, and there are several of them.

I've used both the MultipartRequest class from 
http://www.servlets.com/cos/ and the FormFile class from Struts 
successfully; FormFile in a portlet and MultipartRequest in a servlet.

You should be able to use the same ideas in the portlet situation as you 
would in a servlet so a Google search would give you the exact answer 
you're looking for.

Good luck.
