How do I integrate Sitemesh 3 with Spring MVC 3? - spring-mvc

Question

I am trying to use Sitemesh 3 to control the decoration of JSP output from a Spring MVC application.
When I hit the application it seems that Sitemesh is making a request to the Spring servlet to try and retreive its decorator file. This may, or may not be correct behaviour but it is causing me all many of headaches.
My understanding of Sitemesh 3 is that it does its work after Spring, ie on the Response object.
The error I'm getting in the browser is a 404 and in the logs (config/code follows):
INFO: Server startup in 1367 ms

I suspect it's a problem in my web.xml and how I've defined the mappings(URLs):
<servlet>
<servlet-name>springiness</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springiness</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
<filter-name>sitemeshfilter</filter-name>
<filter-class>uk.co.hermes.filters.SitemeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemeshfilter</filter-name>
<!-- leaving SitemeshFilter class to decide which responses it should decorate -->
<url-pattern>/*</url-pattern>
</filter-mapping>
My custom filter:
public class SitemeshFilter extends ConfigurableSiteMeshFilter {
private Logger log = LoggerFactory.getLogger(SitemeshFilter.class);
/**
* See http://wiki.sitemesh.org/display/sitemesh3/Configuring+SiteMesh+3
*/
#Override
protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
log.debug("** hit the sitemesh filter");
// apply this decorator (template) to the path defined...
builder.addDecoratorPath("/*", "/WEB-INF/decorators/mainDecorator.html");
// ... when the response type matches one of these
builder.setMimeTypes("text/html", "application/xhtml+xml", "application/vnd.wap.xhtml+xml");
}
}
WEB-INF/
|-jsp
|-home.jsp
|-decorators
|-mainDecorator.html
And my super simple Controller:
#RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
return "home";
}

Since no one has posted actual content, here you go:
in pom.xml add:
<dependency>
<groupId>org.sitemesh</groupId>
<artifactId>sitemesh</artifactId>
<version>3.0.0</version>
</dependency>
in WEB-INF/web.xml † add:
<filter>
<filter-name>sitemesh</filter-name>
<filter-class>org.sitemesh.config.ConfigurableSiteMeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
in WEB-INF/sitemesh3.xml add:
<sitemesh>
<mapping path="/*" decorator="/WEB-INF/decorator1.jsp"/>
</sitemesh>
in WEB-INF/decorator1.jsp add:
<html>
<head>
...
</head>
<body>
<sitemesh:write property='body'/>
</body>
</html>
† put this below your Spring Security Filter Chain if using Spring Security.

In my case, I used this little tutorial to make it works.
