You can make your own ActionServlet by extending
RequestProcessor class and overriding its methods. The
example is given below....

package com.visualbuilder;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.RequestProcessor;

public class CustomRequestProcessor extends
RequestProcessor {

public boolean processPreprocess(HttpServletRequest
request, HttpServletResponse response) {

System.out.println("Called the preprocess method before
processing the request");
return super.processPreprocess(request,response);
}
