Struts can be used in its own go on convoluted projects.
There are many net applications offering a enterprising lattice intimacy as a corollary of client-server web-based programming languages. For instance, the JavaServer Pages net programming talking allows integration of databases, sheet designs and flow containment.
This can example to larger applications fitting burdensome to generate and carry on. The Model-View-Controller (MVC) architecture separates these concerns into exclusive components. Write Action classes for each logical request to be executed. Action classes are the basic method of coding and communicating messages between classes.4. Write the action mapping configuration file.
Catch the exceeding components by studying the documentation (gawk Method). The above components are the Servlet controller, JavaServer Pages and Operate Business Logic. The main component is the controller, as messages and interactions take place to and from the controller.
2. Configure the framework using the base servlet provided: org.apache.struts.action.ActionServlet
The configuration settings for the server will need to be included in the web.xml for the servlet settings. The actual configuration will need to be configured in the struts-config.xml file.
It is also necessary to specify the action mappings to handle the Uniform Resource Identifier (URI) for incoming requests. This also defines the application modules.
3. The database attribute is managed by the argument or database regulation, while the flow polity and other principle is handled by the "controller."This can be handled by the Struts framework, which allows the creation of applications creation operate of the MVC architecture.
Instructions
1.The application mapping configuration file is the XML file used to configure the controller servlet named "struts-config.xml".
5. Update the web application deployment descriptor file, using XML. This file is used to deploy the Struts application to a web server and can be any name specified, such as upload_app.xml.
