something like this: (omitting imports, decent error handling, etc)
public class MyFilter implements Filter {
public void doFilter(ServletRequest request,
ServletResponse response,
FilterChain chain) {
HttpServletRequest hrequest = (HttpServletRequest) request;
// make a mutable copy of its parameters
final HashMap myMap = new HashMap(hrequest.getParameterMap());
// put in the extra value, as a string array
myMap.put("foo", new String[] {"bar"});
hrequest = new HttpServletRequestWrapper(hrequest) {
// now override the parameter methods to use mymap
public Map getParameterMap() { return myMap; }
public String getParameter(String name) {
String[] value = getParameterValues(name);
return value == null || values.length() == 0 ? null : values[0];
}
public String getParameterValues(String name) {
return (String[]) myMap.get(name);
}
public Enumeration getParameterNames() {
return Collections.enumeration(myMap.keySet());
}
};
chain.doFilter(hrequest, response);
}
//... etc
}
