=====================================
我的webservice 文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">

<service>
<name>SimpleWs</name>
<namespace>wsclient.server.ws.mjp.com</namespace>
<serviceClass>com.mjp.ws.server.ISimpleWs</serviceClass>
<implementationClass>com.mjp.ws.server.SimpleWsImpl</implementationClass>
<style>wrapped</style>
<use>literal</use>
<scope>application</scope>
</service></beans>
ws 方法：
public String example(String message);

js 调用 soap 数据
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><sample xmlns="wsclient.server.ws.mjp.com"><message>{aa:123}</message></sample></soap:Body></soap:Envelope>
然后返回 500 错误
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>Invalid operation: {wsclient.server.ws.mjp.com}sample</faultstring></soap:Fault></soap:Body></soap:Envelope>
是啥原因？ 谢谢
问题补充：
我java 客户程序调用没有问题
主要是 看的 js ajax调用 是不是有问题？

我的调用方式：
webservice.postWs("sample","adsfas",function(data){
  alert(data);
  });

看看这个吧 我一直都是用这个的

500 错误一般都是ws服务端的 你先写个java程序调用试试 如果成功了再用js测试

ws发送的是soap 只要你能够通过http协议发送soap任何语言都可以 和框架首先肯定无关 框架主要是为了编码简单
