The struts-config. xml configuration file is a link between the View and Model components in the Web Client. It plays an important role in building both Controller components and Application-specific configurations. In Web NMS, this file is created specific to every application in the format as
Struts is an open source framework that extends the Java Servlet API and employs a Model, View, Controller (MVC) architecture. It enables you to create maintainable, extensible, and flexible web applications based on standard technologies, such as JSP pages, JavaBeans, resource bundles, and XML.
The core configuration file for the framework is the default ( struts. xml ) file and should reside on the classpath of the webapp (generally /WEB-INF/classes ). The default file may include other configuration files as needed.
The Struts Framework is an open-source Web application framework used for creating Java Enterprise Edition Web applications quickly and efficiently. It makes use of and further extends the Java Servlet API to promote the model-view-controller (MVC) architecture.
WHAT IS OGNL INJECTION (OGNL)? Object-Graph Navigation Language is an open-source Expression Language (EL) for Java objects. Specifically, OGNL enables the evaluation of EL expressions in Apache Struts, which is the commonly used development framework for Java-based web applications in enterprise environments.
|Sr.No||Components & Description|
|1||Action Create an action class which will contain complete business logic and control the interaction between the user, the model, and the view.|
|2||Interceptors Create interceptors if required, or use existing interceptors. This is part of Controller.|
The controller servlet uses a struts-config. xml file to map incoming requests to Struts Action objects, and instantiate any ActionForm objects associated with the action to temporarily store form data. The Action object processes requests using its execute method, while making use of any data stored in the form bean.

A structural member, subjected to an axial compressive force, is called a strut. As per defi- nition, a strut may be horizontal, inclined or even vertical. But a vertical strut, used in buildings or frames, is called a column.
The struts application contains two main configuration files struts. xml file and struts. properties file. The struts.
web. xml defines mappings between URL paths and the servlets that handle requests with those paths. The web server uses this configuration to identify the servlet to handle a given request and call the class method that corresponds to the request method.
Struts provide structural support by connecting the upper strut bearing to the lower ball joint. This allows the strut to move as the tire is turned. Your vehicle’s suspension is in charge of keeping your tires in contact with the road surface at all times. Struts are a dampening device for your vehicle.
A strut is a structural component commonly found in engineering, aeronautics, architecture and anatomy. Struts generally work by resisting longitudinal compression, but they may also serve in tension.
After 18 years on the market, the Apache Struts project is still widely used by enterprises globally, with estimates suggesting that in 2017 at least 65 percent of the Fortune 100 companies relied on web applications built with the Apache Struts framework.
An OGNL injection vulnerability exists in Atlassian Confluence. The vulnerability is due to insufficient validation of user input used to set variables evaluated in Velocity templates within single quotes.
The Expression Language (EL) simplifies the accessibility of data stored in the Java Bean component, and other objects like request, session, application etc. There are many implicit objects, operators and reserve words in EL. It is the newly added feature in JSP technology version 2.0.
OGNL is the Object Graph Navigation Language (see [http://commons.apache.org/proper/commons-ognl/] for the full documentation of OGNL). … OGNL has a notion of there being a root (or default) object within the context. In expression, the properties of the root object can be referenced without any special “marker” notion.
Strut is defined as to walk in a stiff, swaggering way. An example of to strut is for a person to walk into a room in such a way as to appear that he is better than everyone else there. A structural element used to brace or strengthen a framework by resisting stress or compression.

web. xml defines mappings between URL paths and the servlets that handle requests with those paths. The web server uses this configuration to identify the servlet to handle a given request and call the class method that corresponds to the request method (e.g. the doGet() method for HTTP GET requests).
1. 3. FilterDispatcher was the filter that was provided by Struts 2 for handling all request which needs to be controlled by struts framework. After Struts 2.1. 3 use of this filter was deprecated.
In Struts1 you can use the attribute parameter from element(struts-config. xml) and access it’s value within the action class via the actionMapping. getParameter() method. For actions requiring multiple steps, the parameter is often used to indicate which step the mapping is associated with.
Struct is a composite type means it can have different properties and each property can have their own type and value. Struct can represent real-world entity with these properties. We can access a property data as a single entity. It is also valued types and can be constructed with the new() function.
Struts controller uses the Command design pattern and the action classes use the Adapter design pattern. The process() method of the RequestProcessor uses the Template method design pattern. Struts also implement the following J2EE design patterns.
SpringStrutsIt does not support tag library.It supports tag library directive.It has loosely coupled modules.It has tightly coupled programming modules.

Answers. It is an empirical formula used for the calculation of ultimate load both for short and long columns. Rankin’s formula is also known as Rankin Gordon Formula. It gives the ultimate load that column can bear before failure. If column is short, calculated load will be known as crushing load.
With Struts 1.2, it was required to put the struts-config. xml in the classpath (under WEB-INF folder) but with Struts 2.0, it is required to be in src/main/resources folder.
Q 14 – Which of the following is true about struts-config. xml? … xml configuration file is a link between the View and Model components in the Web Client. B – In form-beans section, you can map your ActionForm subclass to a name.
MVC2 Pattern is the struts framework based – Struts.
xml for servlet based application if you are using servlet version >3.0 and tomcat 7 as it will not run in the previous versions of tomcat. Annotation represents the metadata. If you use annotation, deployment descriptor (web. xml file) is not required.
Filters in web. xml are used for filtering functionality of the Java web application. They intercept the requests from client before they try to access the resource. They manipulate the responses from the server and sent to the client.
- From the File menu, choose New File.
- In the New File wizard, select the Web category, then select Standard Deployment Descriptor under File Types.
- Click Next.
- Click Finish. A basic web. xml file appears in web/WEB-INF/ .
Struts comes with a special action controller class called ForwardAction (org. apache. struts. actions. ForwardAction), to do the “forward-only” task as name described, and allow you to access the specified JSP page directly.
An ActionForward represents a destination to which the controller servlet, ActionServlet , might be directed to perform a RequestDispatcher. forward() or HttpServletResponse. sendRedirect() to, as a result of processing activities of an Action class.
The action tag allows the programmers to execute an action from the view page. They can achieve this by specifying the action name. They can set the “executeResult” parameter to “true” to render the result directly in the view.
Even though they do the same thing, shocks and struts are completely different parts. A shock cannot be used to replace a strut and a strut cannot be used to replace a shock. … The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system where a shock is not.
