Hallo Brian,
its couious, at first i have programmed a little example Application with
a form and one Servlet. It works ...
But in my productive Code something strange happens ...
Know i hava some Debugging Code added to the servlet.
System.out.println("-------------------------------------------------");
boolean isMultipart = ServletFileUpload.isMultipartContent
(request);
ParameterContainer paramContainer = new
ParameterContainer();
request.getSession().setAttribute("paramContainer",
paramContainer);
Enumeration<String> headerNames = request.getHeaderNames()
;
while(headerNames.hasMoreElements()){
String nameH = headerNames.nextElement();
System.out.println("Header Name: " + nameH + "
Header Value: " + request.getHeader(nameH));
}
System.out.println("Path Info: " + request.getPathInfo());
System.out.println("Content Type: " +
request.getContentType());
System.out.println("Content Length: " +
request.getContentLength());
System.out.println("Path Translated: " +
request.getPathTranslated());
Enumeration<String> parameterNames =
request.getParameterNames();
while(parameterNames.hasMoreElements()){
String pName = parameterNames.nextElement();
System.out.println("Parametername: " + pName + "
Parametervalue: " + request.getParameter(pName));
}
System.out.println("Query String: " +
request.getQueryString());
ServletInputStream sI = request.getInputStream();
String s = null;
BufferedReader in = new BufferedReader(new
InputStreamReader(request.getInputStream()));
for (String buffer;(buffer = in.readLine()) != null
;s+=buffer + "\n");
System.out.println(s);
The result in the logging File of Tomcat is:

Betreff: Re: Commons Upload: Can not read parameters if input type
file is empty ...
The code and HTML look good. I've gotten that message a number of times
and what it generally means is that the request body isn't properly
formatted. More specifically, when the MultipartStream is asking the
underlying stream (in this case the ServletInputStream) for more bytes it
returns -1 signifying the end of the body.
Is anything else touching the InputStream before your code does? That
could cause issues.
Another thing I would try is to read in the request body and output to
stdout. This will help you determine if it looks like properly formatted
multipart body. You could also post that output to the list and we can
take a look as well.
