Get the HttpServletRequest (request) object from Java code

Question

I need to get hold of the request object in Java code. I can\'t pass this object down to my code for certain reasons. Is there any way I can say something like: getCur

Jon Skeet said practically everything, but one clarification to his advice "just the bits that you need" - if you need your request parameters passed down, but you don't need a dependency on HttpServletRequest, pass request.getParameterMap().

And extending a bit on the ThreadLocal option - you can have a Filter which handles all incoming requests, and sets the request in a

public final static ThreadLocal httpServletRequestTL =
      new ThreadLocal();

Because you are setting it on each request (careful with the filter mapping), you won't have to worry about the servlet-container thread pool - you will always have the current request.

P.S. this is the logic behind the spring utility proposed by skaffman - I join him recommending the stable component, rather than making your own.
