JSP Tutorials - Herong's Tutorial Examples - Version 4.03, by Dr. Herong Yang
Code 1 - Display Options - UploadInit.html
This section provides a tutorial example of a static HTML page, UploadInit.html, presenting different upload options for the user to try different ways to upload a file
Now we know how to write a HTML page for uploading files. What's next is to know how to handle the uploaded files embedded in the HTTP request on the Web server side.
Unfortunately, normal Web servers do not offer any support to handle the uploaded files. JSP also does not offer any support to handle the uploaded files automatically. We need additional special programs on the Web server side to do this job.
Of course, there are a lot existing programs available on the Internet that can be installed on the Web server to handle uploaded files. But writing such a program yourself is also not very hard. I am planning to write following JSP pages to create a file upload test application:
As Part 1 of the file upload test, here is my UploadInit.html page, which will let you change the upload settings to see how your browser is submitting different types of input fields with different encryption types:
<?xml version="1.0"?> <html><body> <!-- UploadInit.html - Copyright (c) 2012, HerongYang.com, All Rights Reserved. --> <b>File Upload Test Settings:</b><br/> <form action="UploadForm.jspx" method="get"> File upload handler:<select name="action"> <option>UploadDump.jspx</option> <option>UploadSave.jspx</option> </select><br/> Submit method:<select name="method"> <option>get</option> <option>post</option> </select><br/> Encryption type:<select name="enctype"> <option value="x-www-form-urlencoded"> application/x-www-form-urlencoded</option> <option value="form-data">multipart/form-data</option> </select><br/> <input type="submit" name="submit" value="Submit"><br/> </form> </body></html>
