Re: [s2] getting servletContext in actions
hi Joe, Implementing the ResourceLoaderAware interface has solved my problem. many thanks! i havent tried to use ServletContextAware but I think it will work equally well. many thanks Jeff On 31 Jan 2007, at 16:38, Joe Germuska wrote: Jeff: I think there are a lot of possible routes, but I'm not sure I understand your goal. Could you just have your service implement ResourceLoaderAware? If your Spring ApplicationContext is a WebApplicationContext (as it would be if set up by ContextLoaderListener), then the ResourceLoader would check the ServletContext for resources in addition to the class path, etc. If you don't want your service to implement a Spring interface, there are some Spring beans that help bridge the gap, briefly name-checked here http://www.interface21.com/news-home/2005/spring-1.1.4-released These mostly just let you apply ServletContext attributes to Spring beans in various ways without binding your code to the Servlet API.

Re: [s2] getting servletContext in actions
Hi Tom,
I have tried your suggestion, my applicationContex.xml is now defined
as,
method="getServletContext"/>
class="org.springframework.web.context.support.ServletContextResource">
my StrutsServletContextLoader class consists of one method
public ServletContext getServletContext() {
return ServletActionContext.getServletContext();
}
i am getting error from spring complaining missing servlet context.
You mentioned ServletActionContext needs to the executed within the
context of a webwork request, i think the problem is related to that.
Do you know how can i make my StrutsServletcontextLoader be executed
within a webwork request?
many thanks
Jeff

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.

The struts-default package does include this.

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

setup, while you'd have a lot more awkward setup to do to make
sure that
ServletActionContext.getServletContext was prepared to return a
