From: Kenneth P. Turvey on 17 Jul 2008 15:53 I'm having some difficulty getting file upload to work. I'm using some sample code of questionable utility and I was hoping someone here could give me a hand. The basic problem is that I need to post to a servlet an image and some associated metadata. It should look just like it does when it is posted by the following web page: <html> <head> <title>Image Uploader</title> </head> <body> <form method="POST" enctype="multipart/form-data" action="http://www.squeakydolphin.com/ImageUpload/ImageUpload"> Category<input type="text" name="Category" /><br/> UserId<input type="text" name="UserId" /><br/> Image<input type="file" name="Image" /><br/> <input type="submit" /> </form> </body> </html> It is accepted as multipart data on the server end and that works fine. I just can't seem to get the client to produce the write output. Is there a class library I can use to ease getting this correct? Thanks for any help you can provide. -- Kenneth P.

I got it working with HttpClient. Thanks for the help, both of you. HttpClient really makes this stuff much easier. -- Kenneth P.
