When you return null from any Action class execute method, that tells
framework not to bother about doing any forward or include or
anything. This means you need to handle the response by yourself.
Something like...
response.setContentType("text/plain");
response.getWriter().write("Bingo, you got it.");
Since you are not doing anything to handle the response, you will get errors.
Like I said in my last mail, you need AJAX to do something without
reloading the page. Check these:
http://struts.sourceforge.net/ajaxtags/index.html
