Dynamic forward and recursion in Action's execute method

[Rick Ashley <ri...@hotmail.com>]

Hello,

I have a own DispatchAction based class that should add more parameter's
dynamically to URI at runtime. Problem is that if I try to create a new 
ActionForward instance  e.g. /my/app/myaction?method=doIt&p=100 with a new 
parameter, programs starts to run in recursion.

I want to do this so dynamically that I don't need struts-config.xml
to get a handle to ActionForward objects or anything else. So, is this 
possible in Struts or what I am doing wrong? I use Struts's version 1.1 b2.

Below is sample code of my own DispatchAction class

- r.i.a

public class MyDispatchAction extends DispatchAction
{
// Overrided execute-method
public ActionForward execute(ActionMapping mapping,
			     ActionForm form,
			     HttpServletRequest request,
			     HttpServletResponse response)
     throws java.lang.Exception
{
   // getPath() returns e.g. /app/action.do?method=SomeAction
   String uriPath = mapping.getPath();
   StringBuffer sParams = new StringBuffer();

   // Adding another parameter dynamically.
   sParams.append(addParam(uriPath,
  			   "myParam",
			   "110"));
   ActionForward fwd =
	new ActionForward(sParams.toString());

   return fwd;  // Causes recursion!!!!!
}

// Toolmethod by T.Husted
public String addParam(String path, String name, String value)
{
   StringBuffer uri = new StringBuffer(path);
   boolean isQuery = (path.indexOf("?") >= 0);

   if (isQuery)
       uri.append("&");
   else
       uri.append("?");

   uri.append(name);
   uri.append("=");
   uri.append(value);
   return uri.toString();
}

}
