java - NullPointerException - Java - WCF 之上的 Web 服务客户端(使用 WS-Security)

Question

我正在使用 wsHttpBinding 构建 WCF 服务。(具有 WS-Security 和消息级安全性)

现在我想为其构建一个 JAVA 客户端，使用..

• 地铁
• Netbeans

到目前为止，一切都运行良好。我已经从 WSDL 创建了 Java 客户端。

现在，每当我调用客户端代理时，我都会收到以下错误:

Answer 1

从 Metro 2.0 升级到 Metro 2.3 有很大帮助，至少你会看到一个有意义的异常，在我的例子中，加密算法在我的 JRE 安装中不可用，我必须安装 Bouncy CaSTLe 加密库(http://bit.ly/8JWAF)。

编辑:这是一篇关于 jax-ws 客户端与 WCF 服务通信的文章，希望它有所帮助:Comunicating Jax-ws client with WCF service with server sertificate
