我想通过 SOAP 方法从 CEP 调用 BPS 流程，但在 BPS 端出现异常。

事件输出格式化程序，例如：

 <?xml version="1.0" encoding="UTF-8"?>
 <eventFormatter name="output_formatter" statistics="disable"
     trace="enable" xmlns="http://wso2.org/carbon/eventformatter">
 <from streamName="output" version="1.0.0"/>
  <mapping customMapping="enable" type="xml">
  <inline>
  <TestEchoRequest>
    <input>{{meta_output}}</input>
  </TestEchoRequest>
</inline>
</mapping>
<to eventAdaptorName="outputadapter" eventAdaptorType="soap">
<property name="headers">SOAPAction:"http://wso2.org/bps/sample/process" </property>
<property name="username">admin@carbon.super</property>
<property name="password">admin</property>
<property name="url">http://192.168.20.213:9767/services/TestEcho/</property>
</to>
</eventFormatter>

但从 Enter Event Formatter Details 来看，headers 属性与 XML 版本不匹配，丢失了“SOAPAction”的下半部分。

如果从 Event Stream Simulator 触发事件，BPS 会出现异常：

TID[-1234] [BPS] [2015-08-27 09:51:08,064] ERROR {org.apache.axis2.engine.AxisEngine} - The endpoint reference (EPR) for the Operation not found is http://192.168.11.250:9767/services/TestEcho/ and the WSA Action = . If this EPR was previously reachable, please contact the server administrator.

CEP发送的消息是这样的，好像丢失了SOAPAction头：

POST / HTTP/1.1
Content-Type: text/xml; charset=UTF-8
SOAPAction: ""
User-Agent: Axis2
Host: 192.168.20.213:9767
Transfer-Encoding: chunked

这是一个错误还是任何建议？

以上是 WSO2 CEP 3.1.0 中的一个已知问题，请参阅 [1]。作为一种解决方法，您可以调用 TestEcho 服务的 soap12 端点，因为 SOAPAction 属性在 soap12 中是可选的（为 url 属性添加带有 soap12 端点的完整 url）。

例如， http: //192.168.20.213 :9767/services/TestEcho.TestEchoHttpsSoap12Endpoint/
