Re-use Sitemesh layout

Question

I have a few webapps that I want to reuse an identical layout for. I was hoping I could bootstrap the layout via dependency consumption with the simplest method being:

<sitemesh>
    <property name="decorators-file" value="classpath:path/to/decorators.xml"/>
    <excludes file="${decorators-file}"/>

But that throws an exception.

I guess another option is to have some build trickery to copy the resources to the WEB-INF folder, but that seems like a hack.

I'd prefer some sort of Spring solution (I'm using SpringMVC). I wish Spring had some sort of namespace config so that I could essentially embed the sitemesh.xml and/or decorators.xml.

Does anyone know a way to accomplish this? Does Tiles have something like this?
