strruts file upload problem(illegal argument exception)

[giggi]

Hi,
I am trying to do file upload using struts1.1. I am getting
illegal argument type exception(stack trace attached below). I am struggling
to fix this since three days. I would really appreciate any kind of
help.

I am using web logic 8.1, eclipse and java for my development.
I created a form with property type FormFile.
jsp with input field <html:file property="theFile"/>

and a submit button<html:submit/>. In action class I am just getting
the file with form.getTheFile() method. but the problem is that when I
hit submit button I am getting the following exception:
<Error> <HTTP> <BEA-101017> <[ServletContext(id=314
99063,name=cms-int-20040605,context-path=/cms-int-20040605)] Root cause
of Servl

You wouldn't happen to be using Opera as your browser? I recall having
issues with it and file uploads with Struts. It looked similar to what
you're describing.
