You can handle such cases using the tiles support in Spring.

Define a component in tiles, and designate a ComponentControllerSupport 
subclass to it in your tiles config file, like this:

<definition name="name" page="/somepage.jsp" controllerClass="subclass of 
ComponentControllerSupport"/>

In that subclass, you fetch all the data that is required as the model for the 
view (the tiles component, which is a regular jsp page).

There is some info at www.springframework.org/docs/integration/tiles.html , 
but the controllers are not mentioned.
