Jquery + servlet complete file upload with progress bar appended (any jsjquery plug-in is required)

I can only tell you that js cannot know the upload progress. If you want to use js, you can use ajax to constantly ask the server. How much I uploaded, but the efficiency can be imagined. Currently, flash is used to upload progress bars. The specific name is missing.
There is a jquery hi.baidu.com/..0.html
 
Jsp + servlet implements file upload and download. The source code is online. This problem occurs during file upload.

FileUploadServlet is unavailable.

Check if your Servlet is configured in web. xml?
