IBM 集成总线：SOAP 请求收到 HTTP 错误状态代码'500'

Question

我是Ibm集成总线的新手，一直在努力将数据从http节点转换为SOAP节点。我的消息Flow

问题是，当我使用SOAP输入时，它是有效的，但当我用Http输入更改它并将数据从JSON转换为XML时，错误不断出现。

计算节点代码：

DECLARE reftoOut REFERENCE To OutputRoot.XMLNSC.ns2:MessageExtraitRequest;
DECLARE reftoIn REFERENCE To InputRoot.JSON.Data;


SET reftoOut.ns2:No_du_compte = reftoIn.No_du_compte;
SET reftoOut.ns2:Date_operation = reftoIn.Date_operation;
SET reftoOut.ns2:REFERENCE = reftoIn.REFERENCE;
SET reftoOut.ns2:Libelle = reftoIn.Libelle;
SET reftoOut.ns2:Date_valeur = reftoIn.Date_valeur;
SET reftoOut.ns2:DEBIT = reftoIn.DEBIT;
SET reftoOut.ns2:CREDIT = reftoIn.CREDIT;

我的WSDL(它可以很好地与SOAPInput和poster配合使用(

错误消息的重要位为：

BIP3754E: The SOAP Request Node or SOAP Async Request Node WS_MF
encountered an error while processing the outbound SOAP request.
BIP3711E: A SOAP request received an HTTP Error Status Code '500',
but the response message body was not a SOAP fault.

换句话说：端点http://localhost:8000/wsdl的回复不是有效的SOAP回复；也许是纯文本。您应该分析这个端点，找出它为什么没有回复正确的SOAP回复。
