Hello Everyone!
I am trying to upgrade from Struts 2.0.14 to Struts 2.1.8 and have hit a
small snag which I can't seem to resolve through some Google searching.
Following is part of my defined Inteceptor (the intercept method):
...
public String intercept(ActionInvocation invocation)
throws Exception
{
// Get the action context from the invocation so we can access the
// HttpServletRequest and HttpSession objects.
final ActionContext context = invocation.getInvocationContext();
HttpServletRequest request = (HttpServletRequest)
context.get(ServletActionContext.HTTP_REQUEST);
HttpSession session = request.getSession(true);
...
return invocation.invoke();
}
...
As soon as I upgraded to version 2.1.8, I started seeing the following error
when trying to pull the HttpServletRequest object from the context object:
java.lang.NoSuchMethodError:

I looked at the ActionContext API and it appears that the "get(Object)"
method is still valid, but I'm still missing something. With this new
version of struts, how do I ultimately get access to the HttpSession?
Thanks for the help.
