【web.xml页面】

<servlet>

    <description>This is the description of my J2EE component</description>

    <display-name>This is the display name of my J2EE component</display-name>

    <servlet-name>InitSer</servlet-name>

    <servlet-class>servlet.InitSer</servlet-class>

【servlet部分】

public void init() throws ServletException {
// Put your code here
ArrayList<Grade> grades=gradeimpl.queryGrade("");
ServletContext app=this.getServletContext();//得到application的一个容器--属于tomcat
app.setAttribute("grades",grades);
String[] slikes={"唱歌","跳舞","篮球","乒乓","足球"};
app.setAttribute("slikes", slikes);
}
