| <section name="Using FileUpload"> |
| <p> |
| Your application should detect whether or not FileUpload should be |
| invoked, based on the HTTP method and the content type of the request. |
| </p> |
| <p> |
| Assuming that you have decided that FileUpload should be invoked, you |
| might write the following code to handle a file upload request: |
| <pre> |
| // Create a new file upload handler |
| DiskFileUpload upload = new DiskFileUpload(); |
| |
| // Set upload parameters |
| upload.setSizeMax(MAX_UPLOAD_SIZE); |
| upload.setSizeThreshold(MAX_MEMORY_SIZE); |
| upload.setRepositoryPath(TEMP_DIR); |
| |
| // Parse the request |
| List items = upload.parseRequest(request); |
| |
| // Process the uploaded fields |
| Iterator iter = items.iterator(); |
| while (iter.hasNext()) { |
| FileItem item = (FileItem) iter.next(); |
| |
| if (item.isFormField()) { |
| processTextParameter(request, item); |
| } else { |
| processFileParameter(request, item); |
| } |
| } |
| </pre> |
| </p> |
