There is no Tomcat magic configuration parameter to make this happen. Instead, take a look at HttpServletRequestWrapper. You can combine that with a Filter to override the behavior of getParameter() for the pages that need it such that it returns "" instead of "null" when no such parameter value exists.
If you're unfamiliar with the above concepts, check Google, so see: http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters-p4.html
Good luck, justin

Hi,
I have the following JSP fragment:
.... case 1 = <%=request.getParameter("no_such_thing")%> case 2 = ${requestScope["no_such_thing"]} ....
The output of the page is
... case 1 = null case 2 = ...
Is there any way that Tomcat can be configured to not display the word "null" if the value is null? It is easy to replace the above example in case 1 by case 2, but in my case it is not easy to make such change to my existing code base (which I am migrating from another servlet engine that outputs null as ""). I have pages with the <input type=text> elements displaying the string "null" when there is no default value.
Thanks, -- Rick
