Hi David, This sounds like normal behaviour though it seems wierd at first.
The reason you need to be able to recreate the input stream is because HttpClient sometimes needs to recreate and resend the entire request. The most common cause for this is when the server requires authentication, but there are a number of reasons.
If you want to avoid creating the input stream twice your only option is to buffer the content somewhere (memory or disk) and that may or may not prove to be just as slow.
Regards,
Adrian Sutton.

I created a little class called InputStreamPartSource to wrapper an input stream as a part source.
MultipartPostMethod post = new MultipartPostMethod("http://192.168.1.4:8080/someServlet";);
InputStreamPartSource source = new InputStreamPartSource(stream, "business.xml");
FilePart part = new FilePart("business.xml", source);
post.addPart(part);
int status = client.executeMethod(post);
It seems that the abstract class Part is calling createInputStream twice on my source.
Why does it need to create the stream twice?
This causes a bad file descriptor since the stream was already closed after the first call.
The stream is an expensive resource which comes from a CMS system and I prefer not to create it twice.
Is this a bug are normal/required behavior?
InputStreamPartSource Class included below
public class InputStreamPartSource implements PartSource
{
InputStream stream = null;
String filename = null;
int length = 0;
public InputStreamPartSource(InputStream stream, String filename, int length)
{
this.stream = stream;
this.filename = filename;
this.length = length;
}
