| If you now deploy both the Dog and Cat snaps, two new items will appear on the menu bar, each providing content |
| from their respective snaps. |
| </p><p> |
| <img src="images/sampleCat.png"> |
| </p><p> |
| If you look at the Cat page you will see it is also displaying some properties. The Cat Snap is a little more |
| complex, it has it's own <code class="literal">DispatcherServlet</code> defined in its <code class="literal">web.xml</code> and a |
| controller defined using annotations. If you look at the controller code you will see where these two properties |
| come from. |
| </p><pre class="programlisting"> |
| @Controller |
| public class CatController { |
| |
| @RequestMapping("/meow") |
| public ModelAndView cat(HttpServletRequest request) throws IOException { |
| URL host = request.getServletContext().getResource("host:/WEB-INF/sample.properties"); |
| Properties host_props = new Properties(); |
| if(host != null){ |
| host_props.load(host.openStream()); |
| } |
| URL snap = request.getServletContext().getResource("/WEB-INF/sample.properties"); |
| Properties snap_props = new Properties(); |
| if(snap != null){ |
| snap_props.load(snap.openStream()); |
| } |
| return new ModelAndView("index").addObject("host", host_props.getProperty("some.property")) |
| .addObject("snap", snap_props.getProperty("some.property")); |
| } |
| } |
| </pre><p> |
| There are two properties files called <code class="literal">sample.properties</code> located at the same path within both |
| the Cat snap and the host. Each contains a property called <code class="literal">some.property</code> but with distinct |
| value. Looking at the code above you can see the <code class="code">host:</code> prefix being used to ensure the first lookup |
| only looks in the host and skips the snap. These values are then placed in the Model for the JSP page to render. |
