What is a DO file

The DO file extension is a Java Servlet. It is a Web-based Java application executed by a Web server like the IBM WebSphere.

This format is usually mapped to the Struts controller. And it is utilized for the generation of dynamic Web contents.

A servlet is a language class of Java for extending the functionalities of servers hosting programs. It is accessible through a request-response infrastructure model.
This API supported by .do files provides with the ability of creating dynamic Web pages on a server running on the Java platform.
Normally, the dynamic contents are based on the HTML scripting language but can also be from other models like the XML.
Servlets are widely considered as the counterparts of the dynamic contents generated by the ASP.NET, CGI, and PHP technologies.
The functionality of this do extension supports the maintenance of state across various server transactions via HTTP cookies, URL rewriting, or session variables.

The Java package containing the servlet API identifies the interactions that can occur between the servlet and the Web container.

Basically, the Web container is a component of the Web server. It is the responsible for the management of the lifecycle attributed to the servlets.

It also maps a URL to a specific servlet and makes sure that that URL requester has the appropriate access privileges to communicate with its target.

Servlets supported by the DO file format can be generated by the JSP (JavaServer Pages) compiler. Also by template engines like the WebMacro.

Servlets executed in combination with the JSP are referred to as Model 2 patterns.

They are a variant of the model-view-controller outline.

The lifecycle of this do format in relation to the servlet consists mainly of its loading at startup by the container using the init() method.

Upon completion of the initialization, it begins servicing the client requests using the service() method.

The destroy() method is executed in the final stage to end the servlet service.
