jsp能写servlet类 吗 jsp页面当servlet类？
我做一个二次开发，我在想jsp不是能嵌套java代码吗,所以想在jsp页面写servlet类 但是不知道怎么调用，
（不要告诉我写在java里面，因为不行我才写到jsp页面）
在web.xml配置 通过
<servlet>
<servlet-name>testServlet</servlet-name>
<jsp-file>/jsp/test.jsp</jsp-file>
</servlet>
确实能访问到test.jsp 但是不会不调用doGet（） doPost方法
--以下是test.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="com.esoon.cisiss.common.BaseServlet" %>
<%@ page import="java.io.IOException" %>
<%@ page import="javax.servlet.ServletException" %>
<%@ page import="javax.servlet.http.HttpServletRequest" %>
<%@ page import="javax.servlet.http.HttpServletResponse" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<script type="text/javascript">
alert("");
</script>
<%
class testServlet extends BaseServlet{
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.print("----------1-------");
System.out.print("--------2---------");
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
}
%>

一个jsp写doPost干吗，想做什么直接做，想接值直接写request.getParameter
[解决办法]
其实可以在jsp中使用
<%!
public void method(){
}
%>
来定义全局方法提供调用就好了，，
另外 我尝试了使用楼主的方法，但是好像不行，每次都是执行jsp的_jspService ，，设置了url-pattern 亦如此。
我看编译文件终于发现了：
这个servlet是定义在方法内的，直接调用肯定行不通。。
具体我也不会。。

同意5楼啊~具体什么原因我也没试过，感觉配置文件这么写可能有问题吧~
感觉没什么实用价值啊~在jsp里添加java代码本来就很乱，再写servlet恐怕连执行效率都会降低啊~
[解决办法]
jsp最终会编译成一个servlet类，jsp偏向于表示层，servlet注重逻辑，这个你或许试试这个jsp编译成servlet的名字叫啥，在调用。 你这种具体我也没试过！ 求楼下大神解释吧！

不知道我理解的对不，LZ只是想写一个ajax请求，但是不能写JAVA类，只能修改jsp。
$.ajax({
url : "/brokermark/aaa.jsp",
type:'post',
context : this,
data : {"ddd" : "111"},
error : function(jqXHR, textStatus, errorThrown) {
alert();
},
success : function(data, textStatus, jqXHR) {
alert(data);
}
});
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%
String ddd = request.getParameter("ddd");
out.print(ddd+"====");
%>
