Question

I want to perform a simple task ! but dont know if it is possible or not!

I have a groovy class which implements Runnable and it has been running using an ThreadPool! what I want to do in my Runnable class is the following:

    public void run() {
          EventPhoto.withTransaction { status ->

                EventPhoto photo = new EventPhoto(event:eventInstance)

                photo.imageUrl = "${resource(dir:'images/uploads',file:image.name, absolute:true)}"
                photo.thumbnailUrl = "${resource(dir:'images/uploads',file:thumb.name, absolute:true)}"
          }
    }

The thing is, as my thread is not running inside the webrequest I am getting the following error:

java.lang.IllegalStateException: No thread-bound request found: Are
you referring to request attributes outside of an actual web request,
or processing a request outside of the originally receiving thread? If
you are actually operating within a web request and still receive this
message, your code is probably running outside of
DispatcherServlet/DispatcherPortlet: In this case, use
RequestContextListener or RequestContextFilter to expose the current
request.

So Is there anyway to still use $resource() ??

thanks
