跨应用获取application和session属性值

online应用

ServletContext onlineContex=this.getServletConfig().getServletContext().getContext("/online");?  if(onlineContex==null){??? out.print("onlineContex=null");    return;  }? HttpSession onlineSession=(HttpSession)onlineContex.getAttribute("online");   if(onlineSession.getAttribute("hello")!=null){???? out.print(onlineSession.getAttribute("hello"));??? ?}?

?另外注意online的数据源配置Context里需加上 crossContext="true"属性
