What is a DO file?
The files that contain the .do file extension are normally used to generate dynamic Web pages for websites on the Internet. The DO files contain Java program pages that have been created with the purpose of being run by a web server, with the information then being transferred back to the user's Web browser.
Files with the .do file extension work much in the same way that a PHP file works. The DO files are also known as Java Struts Application Files because the DO file provides an associated URL with the ability to "map" to specified Struts actions.
