Hello, I have seen a few references to this problem but have not seen any known solution. I have a scenario where I want to create a mock request/response and forward that on using servletContext.getRequestDispatcher(myJspPath).forward(req, resp); I have created FakeRequest and FakeResponse which implement HttpServletRequest and HttpServletResponse respectively. Using Tomcat 5.0.28 I was able to simply use these instances directly in may call to forward. In upgrading to 5.5.19 I started to get a ClassCastException at ApplicationDispatcher line 814. I then found in the RequestDispatcher specs for forward: The request and response parameters must be either the same objects as were passed to the calling servlet's service method or be subclasses of the ServletRequestWrapper<http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletRequestWrapper.html>or ServletResponseWrapper<http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletResponseWrapper.html>classes that wrap them.
So I then wrapped these fake request/response objects in a HttpServletRequestWrapper and HttpServletResponseWrapper but this has the same results. Am I reading the specs incorrectly? Does the wrapper that I use have to be, in this case, the tomcat specific wrapper that is used internally? If this is the case, is there any sort of work around that I can use to get the intended results? Any insight would be appreciated. -Brandon
