I'm having a lot of difficulty getting file uploading to work using Teapot/Zinc. The documentation is not entirely clear about how it's supposed to work, and the example provided doesn't quite work. I'm referring to section "4.6 Submitting HTML Forms" in "Enterprise Pharo â a Web Perspective." Here's my setup... I have a Teapot route like: GET: '/upload-handler' -> [ :req | self uploadHandler: req ]; where uploadHandler: req ^ '<div> <form method="POST" action="upload-handler" enctype="multipart/form-data"> <input type="file" name="fileupload"> <input type="submit" value="Upload!"> </form> </div>' I have a submission form like: GET: '/submission' -> [ :req | self submissionPage: req ]; POST: '/submission' -> [ :req | self handleSubmission: req ]; where submissionPage: req ^ '<div> <form method="POST"> <input type="file" name="fileupload" value=""> <input type="submit" value="Submit"> </form> </div>' handleSubmission: req ZnClient new url: 'http://174.117.171.194/upload-handler'; addPart: (ZnMimePart fieldName: 'fileupload' fileNamed: 'S1-ABCD012345.st' ); post. When I submit the submission form, I get "FileDoesNotExist: File @ /S1-ABCD012345.st". It doesn't matter what path I use to get to S1-ABCD012345.st. I tried "/Users/richardeng/Documents". I tried "/Documents". I tried "/". I don't know what path it's looking for. The file is there â there's no reason why it can't find it. I guess I'm just not understanding how this whole thing is supposed to work. Any ideas? Richard
