http://issues.apache.org/bugzilla/show_bug.cgi?id=31931 request wrapper class is not pluggable ------- Additional Comments From [EMAIL PROTECTED] 2004-10-28 05:16 ------- Hmm ... looks like RequestProcessor.processMultipart() always uses a MultipartRequestWrapper if the content type is "multipart/form-data". The controller setting you are trying to change sets the MultipartHandler class, not the request wrapper class. One could argue that the wrapper class ought to be pluggable as well (if you believe so, the best thing would be to submit an enhancement request into http://issues.apache.org/bugzilla/). In the mean time, one thing you can do is use the getRequest() method of each wrapper, and walk up the chain of wrappers to find the one you want. Something like: MySpecialRequest myRequest = null; if (request instanceof MySpecialRequest) { myRequest = (MySpecialRequest) request; } else if (request instance of HttpServletRequestWrapper) { HttpServletRequestWrapper wrapper = (HttpServletRequestWrapper) request; while (wrapper != null) { if (wrapper instanceof MySpecialRequest) { myRequest = (MySpecialRequest) wrapper; break; } wrapper = (HttpServletRequestWrapper) wrapper.getRequest(); } } You'll run into problems if for some reason your wrapped request isn't in the stack, so you might put some extra error checking in for that ... but something along these lines should get you access to the special things in your wrapper.
