I have read this below para from a website :
When a Action class requires objects such as the HttpServletRequest ,that can be obtained by asking the ActionContext or implementing ServletRequestAware.
Could anybody please tell me any scenario where a Action class requires HttpServletRequest object ??
Thank you very much .
I myself see very little or no use of binding your Action with HttpServletRequest object.I believe idea is to provide a way to access these objects in some specific use-case (which i myself have not seen so far)
It is more difficult to test Actions with runtime dependencies on HttpServletRequest.I myself looking forward if some one can come up with any such use-case where its like must to get a reference of HTTP object in Action Class as using such reference are against Struts2 philosophy of POJO action classes.
