我想通過jsp中的jquery ajax請求來整合json。我正在使用org.json.simple包。客戶端的每一件事情都很好,但是從服務器響應中我得到了500個服務器代碼錯誤和4個readyState代碼。jsp json服務器:500錯誤
我得到的迴應是:
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);

Stacktrace:
我用來發送響應的JSP代碼:

pageEncoding="ISO-8859-1"%>
<%@ page

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

我使用Eclipse IDE中。我已經在項目中導入了jar文件。我已經重新啓動服務器並重新啓動了eclipse。 我在這裏做錯了什麼?
除了具體問題之外,您是否意識到您在此處將HTML與JSON混合在一起,並且您將JSON發送爲HTML? JSP在這裏是錯誤的工具。而是使用一個servlet。對於一些例子,檢查這個問題:http://stackoverflow.com/questions/4112686/update-current-page-with-a-servlet – BalusC 2011-04-02 21:00:02
