hi there

i'm traing to send a multipart reqest using the InputStreamRequestEntity
in httpclient 3.0.1.
this is the code:

note: clientRequest is an incoming HttpServletRequest, and the stream
used for the InputStreamRequestEntity's constructor is obtained by using
the commons.FileUpload API.

        ServletFileUpload upload = new ServletFileUpload();
        FileItemIterator iter = upload.getItemIterator(clientRequest);
        while (iter.hasNext()) {
          FileItemStream item = iter.next();
          String name = item.getFieldName();
          if (item.isFormField()) {
            postMethod.addParameter(name,
Streams.asString(item.openStream()));
          } else {
            postMethod.setRequestEntity(new
InputStreamRequestEntity(item.openStream()));
          }
        }

Can you check if the 'item.openStream()' returns null? The reason the
exception is thrown is that the InputStream passed on to the
InputStreamRequestEntity is null.

upon executing the post method, the following exception is thrown:

java.lang.IllegalStateException: Content must be set before entity is
written
