∟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:

Part 1 - UploadInit.html - A HTML static page that presents different upload options for the user to try different ways to upload a file.
Part 2 - UploadForm.jspx - A JSP page that presents a file upload form with user selected options. This JSP page also handles the submitted form and passes the uploaded file to other JSP pages for further processing.
Part 3 - UploadDump.jspx - A JSP page that reads the uploaded file and dumps it back to the browser.
Part 4 - UploadSave.jspx - A JSP page that reads the uploaded file and saves it to the server's file system.

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

<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>
