Struts2 Data Tags Struts2 comes with rich tags that can be categorized into data, control and UI tags. This article provide details about majorly used Struts2 data tags with example project.
Struts2 Control Tags Struts2 control tags are used for manipulation and navigation of data from a collection. This article provide details about the Struts2 control tags and how we can use them for conditional flow and iterate over an array or collection.
We also learn about some other control tags used to sort list, merge lists, append lists and take subset of list with example project. UI tags are also responsible for binding form properties to action class properties. This article provide details about mostly used UI tags with example project. Struts 2 Localization Struts2 provides strong support for internationalization through I18nInterceptor and resource bundles. This article explains about i18n support in Struts2 framework with different locations of resource bundles with example project.
The article explains about this interceptor in detail with example project to upload files on server. Struts2 and log4j integration This article explains how we can integrate log4j with Struts2 framework in our web application for logging purposes.
Struts2 Exception Handling Struts2 provide convenient ways to configure error pages for exceptions thrown by our application at global package level as well as action level. Again this is done by Struts2 exception interceptor that is part of defaultStack. Figure 1. Struts 2 Action, Interceptor, and Result View image at full size In this article, learn about dynamic data handling in a Web-based application.
You will explore how to send user data at run time with a few special use cases, such as pre-filling a form with user data values and setting the UI field to display a default value from a list of values.
The article focuses on the implementation details of the flow of dynamic data between Struts 2 Action classes and the result pages. Dynamic data handling using Struts 2 ValueStack ValueStack, one of the powerful features of Struts 2, holds all the data during processing of a request.
Action classes also store data in the form of beans.
Struts The Complete Reference
In Struts 2 you use getter and setter methods. Once the data is stored in the action class objects, Struts 2 puts that data onto the ValueStack in the form of the Action object.
ValueStack stores a stack of objects, and this data will be exposed to the other parts of the framework. In Figure 2, the action class sets the values of two variables using getter and setter methods.
This data will be saved to the ValueStack during processing of requests. Figure 2. Data on ValueStack View image at full size Static data versus dynamic data If data that will be displayed on the UI is known in advance, it can be called static data.
Figure 3 shows a static data situation. Figure 3.
Static data View image at full size If a user wants to display the data retrieved from the user database, you need a mechanism to appropriately handle the data in the Action and JSP and to display the data on the UI. With Struts 2, the building blocks for this type of scenario are the Action class and ValueStack. By using getter and setter methods, the Action class will save the user values onto the ValueStack.
See Figure 4. Figure 4. Dynamic data View image at full size Setting UI fields and tags with user data Struts 2 provides a tag library that displays data in rich and reusable HTML to help you create interactive, form-based applications. Struts 2 comes with generic tags control tags and data tags and UI tags. UI tags are designed to get data from the ValueStack action added data onto the ValueStack or from data tags.
In contrast, server-side scripts utilize the functions provided by the server. When the client sends a request to the server, the server responds to the request by sending some type of content to the client. This HTML is understandable to the browser and tells the browser how to render the data to the viewer.
Further, a Web application can be a combination of both active and passive resources. A passive resource, also known as static resource, is the one which does not have any processing of its own. For example, an HTML file is a passive resource because its contents do not change.
On the other hand, active resources are those which have their own processing. For example, Servlets and JSPs are active resources. They generate the result dynamically. Today, almost all the Web applications include dynamic content or active resources to increase interactivity between the user and the Web application.
Web applications have to face a number of technical challenges, when they are developed using traditional architectures.
Struts 2 Tutorial – Struts2 Tutorial
We have different Web application Frameworks, like Struts 2, that help to build Web applications with reduced number of errors and efforts. A new framework is always developed over some existing technologies, e. Though using a framework alleviates a developer from interacting with different technologies on which a framework is based, a working knowledge of these technologies is required.
HTTP is a network protocol used for communicating between the browser running on the users computer and the Web application running on the Web server. This protocol defines the rules for the ways some data can be transferred and decoded.Using tokens to prevent duplicate form submits Lists with This Book.
The power of Struts 2 lies in its ability to provide clean implementation of the Model-View-Controller MVC pattern with the following features: Actions Part of the framework's architecture, Actions provides clean implementation by keeping all the business logic in one place. What is the best way to learn Struts? Alright, fixed. Thanks for telling us about the problem.
