I am trying to use the 'new' filter api to add a parameter to a request before a servlet is invoked. My first try involved calling getParameterMap()and doing a put() into it. It seems that map is locked readonly. So now I'm looking at HttpRequestWrapper but to use that I think I will have to emulate the whole parameter behaviour just to add a value. has anyone done this before, or can point me at an example?

Form my past reading on the ranch, this seems to be a good article on Filters. Never used Filters so far...... regds. - madhav
