Struts2 + Sitemesh + Freemarker doesn't work

I\'ve tried every example i could find and I can\'t get struts2 + sitemesh + freemarker to work on a simple jsp.

I've tried every example i could find and I can't get struts2 + sitemesh + freemarker to work on a simple jsp.

I have a very simple web.xml, a single action that just goes to index.jsp, and a simple .ftl decorator that just adds some text to the result.

When I hit index.action, the page "seems" to be decorated, but I get the literal ${body} instead of the actual contents.

Here's my setup:

web.xml

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
         version="2.4">

    ${body}<br />

index.jsp

<html>
<head>
    <title>my title</title>
    </head>
<body>
my body

Any ideas???

See http://struts.apache.org/2.x/docs/sitemesh-plugin.html for working docs. You probably need to add:

<servlet-mapping>
     <servlet-name>sitemesh-freemarker</servlet-name>
     <url-pattern>*.ftl</url-pattern>
</servlet-mapping>

to your web.xml.

And rename index.jsp to index.ftl. Incidentally if you're going to go with sitemesh + freemarker I usually prefer the convention of *.dec for the decorators and *.ftl for the freemarker templates.
