How to get context-param from web.xml in struts app

The visibility of Context-param from web.xml is in servlet.In Struts the servlet is the ActionServlet. so in ActionServlet  class to get the context param values

example:

ServletContext cg=getServlet().getServletContext();

String driver = cg.getInitParameter("driver");

program:

package com.java.struts.Login;

import javax.servlet.ServletContext;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionMessages;

import org.apache.struts.validator.DynaValidatorForm;

public class UserLoginAction extends Action

{

public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request,HttpServletResponse response)throws java.lang.Exception

{

String driver,url,user,pwd1;

DynaValidatorForm dform=(DynaValidatorForm) form;

HttpSession session=request.getSession(true);

String result="failed";

try

{

if(session!=null)

{

ServletContext cg=getServlet().getServletContext();

driver = cg.getInitParameter("driver");

url = cg.getInitParameter("url");

user = cg.getInitParameter("user");

pwd1 = cg.getInitParameter("password");

System.out.println(driver+" "+url+" "+user+" "+pwd1);

String username=dform.get("username").toString();

String pwd=dform.get("password").toString();

if(username!=null&&pwd!=null)

{

System.out.println(username+" "+pwd);

System.out.println("success");

}

}

}catch(Exception e)

{

System.out.println(e.toString());

}

return mapping.findForward(result);

}

}
