Struts 2 - Basic

This exam is focused on the struts2 framework which results of the joined forces of the Struts and Webwork comunities to create new version of Struts2 that is simpler to use and closer to what Struts was always meant to be. It covers everything a developer will need to get up and run using struts2 and assumes a working knowledges of some JEE technologies, including:

Filters, JSP, and Tag Libraries
HTML and HTTP
Web Containers (such as Tomcat)
XML

The following topics are not part of the Struts2 Basic exam (they are kept for the intermed exam):

Annotations
Advanced Interceptors
Type Conversion
Advanced Localization
Zero Configuration Pattern
Advanced Validation
Extension

Set up and Configuration
Setup the Web Application Deployment Descriptor (web.xml) 1 question The web.xml web application descriptor file represents the core of the Java web application, it is also part of the core of the Struts framework. Write the web.xml for configuring a basic struts2 web application. Register a FilterDispatcher to initialize and enable framework functionality for handling requests. Explain and define the following optional initialization parameters: config actionPackages	4	5	2	Add a question Beta questions
Setup the Struts Configuration (struts.xml) 1 question Define a basic struts.xml file which is the core configuration file for the framework. Describe the way to break up a large struts.xml into smaller pieces.	2	10	3	Add a question Beta questions
Constants Configuration 1 question Constants provide a simple way to customize a Struts application by defining key settings that modify framework behavior. Describe the several ways we can declare constants.	4	4	0	Add a question Beta questions
Packages Configuration 1 question Packages are a way to group actions, results, result types, interceptors, and interceptor-stacks into a logical configuration unit. Describe package configuration usage.	1	9	2	Add a question Beta questions

Actions
Coding Actions 2 questions Describe basic struts2 action usage. Write actions that perform work with a single result being returned. Write actions that can return different results depending on the outcome of the logic.	10	19	5	Add a question Beta questions
Configuring Actions 1 question Dynamic Method Invocation and Wildcard Method are not covered. Describe action mapping configuration attributes(exception handlers and interceptors attributes are not covered). Describe how to specify multiple results type and a single result type with the action mapping. Explain the way to create more than one entry point to an action with the action mapping "method" attribute.	4	1	2	Add a question Beta questions
Results 3 questions When an Action class method completes, it returns a String whose value is used to select a result element. Describe the way to determine the result for an action (annotation and code behind plugin are not covered). Name the predifined result names defined by the ActionSupport base class. Describe the base result types below semantics: Dispatcher Result Redirect Result Redirect Action Result All the other result types (Chain, Freemarker, HttpHeader, Stream, Velocity, XSL, PlainText, Tiles)are not covered.	5	1	3	Add a question Beta questions
Value Stack/OGNL 3 questions Explain the purpose of the value stack. Describe the OGNL usage in struts2 (only this part of OGNL is covered). List the default variables in the value stack. Enumerate the object that are in the value stack and their usages. Write code that can acces to object placed on the value stack. Describe the several ways you can access the value stack.	12	1	1	Add a question Beta questions
