1. 首先下载好JSON-RPC-JAVA压缩包；
里面包含jsonrpc-1.0.jar 和 jsonrpc.js；
jsonrpc-1.0.jar放在项目的WEB-INF/LIB下
jsonrpc.js 放到你要使用的页面引用；
2. 创建测试程序TestObject.java：
package com.gameframe;
public class TestObject {
public Integer sum(Integer a, Integer b) {
return a + b;
}
}
3. 当前页面引入 <%@ page import="com.gameframe.TestObject"%> <script type="text/javascript" src="js/jsonrpc.js"></script> <body> <jsp:useBean id="JSONRPCBridge" scope="session" class="com.metaparadigm.jsonrpc.JSONRPCBridge" /> <% TestObject t = new TestObject(); JSONRPCBridge.registerObject("TestObject", t); %> </body> 4. web.xml 配置里面加入 <!--servlet config for JSON-RPC-JAVA--> <servlet> <servlet-name>com.metaparadigm.jsonrpc.JSONRPCServlet</servlet-name> <servlet-class>com.metaparadigm.jsonrpc.JSONRPCServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>com.metaparadigm.jsonrpc.JSONRPCServlet</servlet-name> <url-pattern>/JSON-RPC</url-pattern> </servlet-mapping> 5.网页测试代码： <form> <input type="text" name="a" /> <input type="text" name="b" /> <input type="button" οnclick="fnSum(this.form)" value="Sum" /> </form> 6. javascript脚本函数添加 <script type="text/javascript"> function fnSum(form) { try { //Create a jsonrpc object for doing RPC. jsonrpc = new JSONRpcClient("JSON-RPC"); // Call a Java method on the server result1 = jsonrpc.TestObject.sum(form.a.value, form.b.value); alert(result1); } catch (e) {} } </script> 测试页面即可
