Since you set the Content Type to application/x-www-form-urlencoded you must
URL Encode the data.

Subject: Post a file to servlet from application
> Hi.
>
> I am trying very hard to post a binary file and some other parameters to a
> servlet from a java application. The servlet will look at the parameters
> and the associated file and write it to disk. I am having problems
getting
> it in the right format.
>
> I can post any number of name=value pairs fine. However, when I add my
> file byte array after my name=value pairs, it will generate an illegal
> argument exception in my servlet when I call req.getParameter("name").
> This means that I have the format wrong.
>
> Another question: When I send the binary data, do I have to encode that
> also?
>
> Here's the Java application code that posts to the servlet. The servlet
> stuff is pretty simple.

> Thanks. It's close to 1AM and I can't get this fixed!!
