In your struts-config, just define a forward that points to your servlet and have your Action return to that forward. If the parameters you want to add are static, make them part of your forward. If the parameters you want to add are dynamic, once you get get the ActionForward in your Action (via mapping.findForward), you can do a forward.getPath() to get the
String for your path, append "?p1=x&p2=y" or whatever parameters you need to the String, then pass it to forward.setPath() before returning the forward.
