Oh, and another thing, it looks like your action is redirecting to your
jsp instead of forwarding. In struts config, remove the redirect="true"
from your forward. With redirect = true, any request attributes you set
in your action will not make it to your jsp, also request scoped forms
won't work. By changing this, request.getQueryString() will work as you
expect in your jsp so you may not need a filter after all.

One trick that can help you, is to create a variable (a bean) in an
action Struts, so that it can be used in the jsp file.
In step 4/5 (in the action struts), you can set :
request.setAttribute("myQuery", request.getQueryString());
And in your jsp file, you can use it, for example, like this :
<bean:write name="myQuery" />
I'm not perfectly sure that it works, but you can try it.
