Your first JSP Page

In the previous section we learnt how to create a controller. Now that geeMVC has found our controller and has executed our method handler, we want to send some content to the user. For this we returned the string forward: hello-world.

Lets continue with a concrete example by creating a JSP page:

hello-world.jsp

<h1>Hello World</h1>

<p>It worked!</p>

In your Java-IDE it should look something like this: JSP Page

"Hang on" you say, "how does geeMVC know which file to load when we have only specified 'forward: hello-world' and not 'forward: hello-world**.jsp**'?"

This is simply because we told geeMVC so when setting up our servlet in the web.xml, as shown in Setting up your Webapp:

<servlet>
        <!-- The main entry point to geeMVC. -->
        <servlet-name>geeMVC-Servlet</servlet-name>
        <servlet-class>com.geemvc.DispatcherServlet</servlet-class>
        <!-- Tell geeMVC in which folder JSPs or templates reside, relative to 
            the WEB-INF directory. -->
        <init-param>
            <param-name>view-prefix</param-name>
            <param-value>/jsp/pages</param-value>
        </init-param>
        <!-- Specifies the ending of JSP or template files. -->
        <init-param>
            <param-name>view-suffix</param-name>
            <param-value>.jsp</param-value>
        </init-param>

        <!-- [ ... ] -->

<servlet>

Now that we have created our first method handler and JSP page it is time to build the code and start our webserver.
