I developed an Applet for uploading files (some of which will be hundreds of megabytes) over http to a database (through a Servlet). Because of the large files I have to set the HttpURLConnection to chunked streaming mode, like so:

HttpURLConnection con = (HttpURLConnection) myUrl.openConnection();
url.setChunkedStreamingMode( 4*1024*1024 );
...

In the Servlet I wanted to use OrdHttpUploadFormData to make it easier to insert the files in the database tables:

OrdHttpUploadFormData formData = new OrdHttpUploadFormData( request );
formData.parseFormData();
...

But the parseFormData() method returns an Exception:
java.lang.IllegalArgumentException: Buffer size <= 0

Any ideas what causes this and/or what to do to solve the problem?

Thanks and best regards
