JAX-WS 编组错误。 SomeClassV1R5 无法转换为 SomeClass 的目标类型

Question

We have migrated from JAX-RPC to JAX-WS services with Websphere(8.5.5 service pack 13) and default Axis2 implementation. All services are running fine but 1 client getting strange error for the same operations which are working fine for others. We enabled SOAP logs and tried same request with SOAPUI which worked fine. Below is the stack trace. The GetTransactionsV1R8RequestType is not extending GetTransactionsRequestType .

Caused by: javax.xml.ws.WebServiceException: An internal error occurred during JAX-WS marshalling. An object of type com.kk.v1.GetTransactionsV1R8RequestType cannot be converted into the destination type of com.kk.v1.GetTransactionsRequestType

Answer 1

After much struggle I am able find the root cause. In this scenario client calling our API using raw SOAP XML over HTTP . XML has request name as GetTransactionsV1R8RequestType and request is getting validated against XSD/schema successfully. In HTTP connection, client setting SOAPAction property with value as 'getTransactions' which is initial version of API. The request name is XML is getTransactionsV1R8RequestType with which expected SOAP operation is 'getTransactionsV1R8'.

Setting proper SOAPAction value resolved the problem.

Another observation with this is GetTransactionsV1R8RequestType is not extending GetTransactionsRequestType but was extending GetTransactionsV1R5RequestType and if we set SOAPAction value as ' getTransactionsV1R5 ' with SOAP XML GetTransactionsV1R8RequestType , it's get getting successfully called with operation ' getTransactionsV1R5 ' as GetTransactionsV1R8RequestType can be cast to GetTransactionsV1R5RequestType .
