WSO2:RAMPARTUTIL抛出空指针执行选项

我用RAMPART实现创建了一个web服务

服务流程： 发件人->使用其私钥对邮件签名->使用服务器公钥加密邮件->发送给收件人 接收者->使用发送者的公钥验证消息->使用其私钥解密消息->处理信息

问题: 客户端正在对消息进行签名和加密并发送到服务器 服务器正在成功验证和解密邮件。 现在， 对消息进行解密后，服务器将处理这些值 &必须回复客户端状态。 返回时，我收到以下错误：

SEVERE: Servlet.service() for servlet [AxisServlet] in context with path [/webService] threw exception

另外，我在没有RAMPART的情况下实现了该服务，在这种情况下，响应是成功的

请告诉我，过去两天来我一直在努力。。

由于请求解密成功，无法理解m i缺少什么，但响应引发异常。

我添加了以下块，错误已解决：

<sp:Wss10 xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
  <wsp:Policy>
    <sp:MustSupportRefKeyIdentifier/>
    <sp:MustSupportRefIssuerSerial/>
  </wsp:Policy>
</sp:Wss10>

感谢您在3年多前就遇到了这个问题，我也遇到了同样的问题，您的解决方案运行得很好：D
