  3. Open a web browser and navigate to http://localhost:8080/MY_PROJECT_NAME, to display the index page. The server is case sensitive, so make sure the spelling of the project name is correct.

 

The application configuration files

With the default settings the index.jsp composes the index page. It is in the Web Pages/WEB-INF/jsp directory.

The web.xml file in the Configuration Files directory points to the first Java Server Pages file: redirect.jsp

The redirect.jsp file is located in the Web Pages directory

The Dispatcher

The dispatcher-servlet.xml file contains the mapping between the HTML file, controller, and view.

<property name="mappings">
  <props>
    <prop key="index.htm">indexController</prop>
  </props>
</property>

The bean section specifies the name of the view for the controller.

 <!--
 The index controller.
 -->
 <bean name="indexController"
       class="org.springframework.web.servlet.mvc.ParameterizableViewController"
       p:viewName="index" />

Web Application Build and Deployment

To generate a war file of your web application

  1. In the Project Files directory right click the pom.xml file and select Run Maven > Goals
  2. In the Goals field type
    compile war:war

    and click OK

  3. NetBeans creates the war file in the target directory.
