It would be very easy to create a Spring FactoryBean for this.
(Checkout the Spring Documentation if that doesn't make sense) Then, to
access the servlet context, just do a:
ServletContext servletContext = ServletActionContext.getServletContext();
The FactoryBean would allow you to use dependency injection in spring to
inject the servlet context into any spring bean. (I'm doing a similar
thing with some of the our legacy services and components) You could
even convert the ServletContext into a Map to decouple yourself from the
servlet API. That way your process beans would only be dependent on a
Map instead of a ServletContext. Keep in mind that the
ServletActionContext is a thread local, so it must be executed from
within the context of a webwork request.

Hi Joe,
Thanks for the helpful information. I am just wondering is it possible
to get the ServletContext object in my spring applicationContext.xml?
What i am trying to do now is to create a Resource object
(ServletContextResource) and inject into a service class and then use
this service class in a struts action. At the moment, I have to pass
in the resource path (as a string) into the action, instantiate the
ServletContextResource in the action then pass it to the service class.
many thanks,
Jeff

You need to make sure that your action is passing through an
interceptor-stack that includes ServletConfigInterceptor

The struts-default package does include this.
http://struts.apache.org/2.x/docs/struts-defaultxml.html
Another thing you can do is call the static method
ServletActionContext.getServletContext() but this would be harder to
support
in a unit testing environment. If you implement
ServletContextAware, then
you could provide a mock ServletContext implementation in your unit test
setup, while you'd have a lot more awkward setup to do to make sure that
ServletActionContext.getServletContext was prepared to return a usable
value.
