Struts 2 Hello world Example

Hello World Appliction

In this tutorial, we will explain you how to create a simpler Struts 2 application and what are configurations are required before start your application. First we have to follow some fundamental configuration for Struts 2 application. The type of configuration is known as Declarative Architecture.

Declarative architecture is a specialized type of configuration that allows a developer to create an application’s architecture through description rather than programmatic intervention. The developer describes the architectural components in high level artifacts, such as XML files or Java annotations, from which the system will create the run time instance of the application.

Two mechanisms for declaring your architecture
1. XML based declaration architecture
2. Java Annotation based declaration architecture

Lets start with XML architecture :-
The following files are needed for this application.

1. web.xml
2. struts.xml
3. HelloWorld.java
4. index.jsp
5. success.jsp
6. error.jsp
