Multiple file download using jsp

Inside the scriptlet call the isMultipartContent method of class ServletFileUpload which takes one parameter request. This method checks whether there is a file upload request or not. It returns the boolean value. The implementation of FileItemFactory means that it creates FileItem instances which keep their content either in memory or disk. While using the DiskFileItemFactory the temporary files are automatically deleted as soon as they are no longer needed.

This is used to constructs an instance of this class which uses the supplied factory to create FileItem instances. Now declare a variable of type List with the initial value null. Use the method parseRequest and pass a request object as its parameter which returns a list of FileItem instances parsed from the request, in the order they were transmitted.

This method will throw FileUploadException if there is any problem while reading or parsing the request. Don't worry this is not going to happen in this example.

A file download is just an HTTP response data stream that has certain characteristics designed to alert the client to the need to save the response contents as a file instead of doing something like displaying it as a web page.

The client will then display a dialog asking the user what directory that response should be written into as a file. There is a reason for the dialog. Downloading Multiple Files As Zip.

It this chrome-compatible? It works fine when using Firefox though. This code is not compatible with chrome. You are commenting using your WordPress. You are commenting using your Google account. You are commenting using your Twitter account. You are commenting using your Facebook account.
