I tried it out. For some reason, I always get this following statck trace. Could you please help?

This exception occurs when your application tries to write to a response that has already been committed. In this case, we use a MutableHttpRequest, which should capture all these writes and allow us to change them later in the filter. However, there may be a few methods - like addHeader perhaps - that aren't handled in the MutableHttpRequest. This is just a guess. Can you share what's happening in your JSP (welcome.jsp) that causes this error? --Jeff Williams 17:22, 20 April 2007 (EDT)
