Description

We are using struts 1.1 with tiles for our web application. During file upload, as the http request is wrapped as a MultipartRequestWrapper object , the org.apache.struts.tiles.UrlController throws ClassCastException at line requestDispatcher.include(...) [ in perform() method ]

On changing the UrlController class to include the following lines , the exception disappers.
// Unwrap the multipart request, if there is one.
if (request instanceof MultipartRequestWrapper)

{ request = ((MultipartRequestWrapper) request).getRequest(); }

this fix was done in RequestProcessor , but didnt make it to the UrlController class.

Exception stack trace :
