--------------------------------------

package org.taink.struts.action;

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts二.ServletActionContext;

import com.opensymphony.xwork二.ActionContext;

public class EmployeeAction {

public String execute() {
ActionContext actionContext = ActionContext.getContext();
actionContext.getApplication().put("application", "application 施用范畴");
System.out.println(actionContext.getApplication().get("application"));
actionContext.getSession().put("session", "session 运用范畴");
System.out.println(actionContext.getSession().get("session"));
actionContext.put("request", "request 运用范畴");
System.out.println(actionContext.get("request"));
return "success";
}

public String test() {
ServletContext servletContext = ServletActionContext.getServletContext();
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
HttpSession session = request.getSession();
request.setAttribute("request", "request**施用范畴");
session.setAttribute("session", "session**运用范畴");
servletContext.setAttribute("application", "application**施用范畴");
return "success";
}
