我正在尝试通过jsp中的jquery ajax请求来集成json。我使用org.json.simple包来实现这一点。从客户端来看,一切都很好,但从服务器响应中,我得到了一个500服务器代码错误和4个readyState代码。
我得到的回应是:
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 12 in the generated java file
Only a type can be imported. org.json.simple.JSONObject resolves to a package
An error occurred at line: 15 in the jsp file: /interceptor_primaryengine_save.jsp
JSONObject cannot be resolved to a type
12: <body>
13: <%
14:
15: JSONObject obj = new JSONObject();
16:
17: String value = request.getParameter("value");
18: obj.put("value",value);

16:
17: String value = request.getParameter("value");
18: obj.put("value",value);
Stacktrace:我用来发送响应的jsp代码是:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page
import="org.jdom.*,java.util.*,org.jdom.input.SAXBuilder,org.jdom.output.XMLOutputter,java.io.*,org.jdom.filter.*,org.json.simple.JSONObject"%>

JSONObject obj = new JSONObject();
String value = request.getParameter("value");
obj.put("value",value);
out.print(value);
out.flush();

</body>
</html>我使用的是eclipse IDE。我已经在项目中导入了jar文件。我重新启动了服务器,也重新启动了eclipse。我到底做错了什么?!

如果在发送响应的webapp的类路径中找不到json-simple.jar,则可以获得该消息。
