从Java访问.net WCF服务

3

我刚开始学Java,打算利用一个我已经熟悉的.NET WCF服务实现一个客户端应用程序来进行学习。

我使用最新的JAX-WS (https://jax-ws.java.net/) 运行wsimport.bat来生成客户端代理,但是我在认证部分卡住了。WCF服务使用应用程序级别的用户名/密码进行身份验证。我不知道在哪里提供凭据。

对于这个WCF服务,在C#中我只需要添加一个服务引用并执行以下操作:

var client = new ServiceClient();
client.ClientCredentials.UserName.UserName = "username";
client.ClientCredentials.UserName.Password = "password";
client.DoSomething();

从 Fiddler 中,调用 client.DoSomething() 会生成以下请求:

<?xml version="1.0"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
  <s:Header>
    <o:Security xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" s:mustUnderstand="1">
      <u:Timestamp u:Id="_0">
        <u:Created>2013-05-20T01:34:28.353Z</u:Created>
        <u:Expires>2013-05-20T01:39:28.353Z</u:Expires>
      </u:Timestamp>
      <o:UsernameToken u:Id="uuid-da5b7b57-dbb4-4c54-b529-f5b41fc728b4-1">
        <o:Username>username</o:Username>
        <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</o:Password>
      </o:UsernameToken>
    </o:Security>
  </s:Header>
  <s:Body>
    <DoSomething xmlns="http://tempuri.org/"/>
  </s:Body>
</s:Envelope>

这是我目前使用的Java代码:

SomeService service = new SomeService();
ISomeService port = service.getBasicHttpBindingISomeService();
DoSomethingResponse response = port.getDoSomething();

这将产生以下请求:
<?xml version="1.0"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
  <S:Body>
    <ns6:DoSomething xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:ns6="http://tempuri.org/" xmlns:ns7="http://schemas.microsoft.com/2003/10/Serialization/"/>
  </S:Body>
</S:Envelope>

缺少 Security 节点,因此我不确定如何在 Java 一侧进行设置。我漏掉了什么?

如果有更适合我的需求的更好的替代方案,我并不完全必须使用 JAX-WS。但是,WCF 服务无法修改或重新配置,因为超出了我的能力范围。

我正在使用最新的JDK在Windows 8 x64上


我目前遇到了非常类似的问题(wsdl中的安全策略与我连接的相同)- 你是否找到了添加安全节点的解决方案?我尝试将回调处理程序添加到我的代码中,但老实说我不太确定自己在做什么,而且我无法让它正常工作。 - kbbucks

您需要从Java客户端创建一个自定义CallbackHandler。我不是Java方面的专家,但我知道我的一些客户使用Metro库与我的WCF Web服务进行通信。
请尝试搜索如何使用/不使用Metro库创建CallbackHandler。
您可以从这里下载Metro库
这是我建议的示例
