Java based configuration and Filters- ConfigurableSiteMeshFilter

[Ilyas Patel]

Hello

I am fairly new to Java and have been tasked with creating a filter to decorate a response depending on a particular HTTP_Referer.

I have created a filter which extends ConfigurableSiteMeshFilter according to the documentation here - http://www.sitemesh.org/configuration.html.

Here is the Class:

public class PageFilter extends ConfigurableSiteMeshFilter {

    @Override

    protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {

        System.out.println("1 : " + builder.toString());

    }

    @Override

    public void init(FilterConfig filterConfig) throws ServletException {

        System.out.println("2");

    }

    @Override

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)throws IOException, ServletException  {

        System.out.println("3");

        chain.doFilter(request, response);

    }

    @Override

    public void destroy() {

        System.out.println("4");

    }

}

Web.xml:

<filter>

        <filter-name>pageFilter</filter-name>

        <filter-class>com.company.mycompany.core.filters.PageFilter</filter-class>

</filter>

<filter-mapping>

        <filter-name>pageFilter</filter-name>

        <url-pattern>/*</url-pattern>

</filter-mapping>

<filter>

        <filter-name>sitemesh</filter-name>

        <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>

</filter>

<filter-mapping>

        <filter-name>sitemesh</filter-name>

        <url-pattern>/*</url-pattern>

        <dispatcher>REQUEST</dispatcher>

        <dispatcher>FORWARD</dispatcher>

</filter-mapping>

The problem I am having is applyCustomConfiguration() is never being called. I have stepped debug and only the doFilter() method is being called.  One of the experience developers tells me this method should be called automatically by the container. 

Is there anything else I need to do?

Thanks
