Open DO File


  • File type: Java Servlet
  • File Developer: Java

 

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

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

 

Essentially, a servlet is a development language class of Java for extending the functionalities of servers hosting programs accessible through a request-response infrastructure model.

 

This API supported by .do files provides the programmer 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 generated using other development 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 file extension supports the maintenance of state across various server transactions via HTTP cookies, URL rewriting, or session variables.

 

How to Open DO Files

These are the programs that you can use to view these do files. The web browser can be used to view a do file

Category: Web Files
File format: Open-Source

Open With Windows: Requires a Web server that supports JSP to run, may be viewed in a Web browser:

Open With Linux: JSP-supported Web browser, may be viewed in a Web browser:
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 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 or by template engines like the WebMacro.
Servlets executed in combination with the JSP are normally referred to as Model 2 patterns. They are considered as 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 terminate the servlet service.
