Getting the below error when calling the webservice (JAX-WS). Because of the below issue, the request XML is not getting properly mapped and the service is failing

Server: Wildfly-8.2.0 (Both the webservice server and client is hosted here)

ERROR

15:12:56,974 WARNING [org.apache.cxf.service.factory.ReflectionServiceFactoryBean] (default task-8) Could not unwrap Operation {http://www.example.org/IFT/}InternalFundTrans to match method "public abstract void org.example.ift.IFT.internalFundTrans(org.example.ift.XferTrnAddRequestType,javax.xml.ws.Holder,javax.xml.ws.Holder,org.example.ift.IFTheadreq,javax.xml.ws.Holder)"

15:12:57,093 ERROR [stderr] (default task-8) Warning: Could not get charToByteConverterClass!

Scenario

This issue is coming when request and response header are part of the input parameter of the web method, else it is working fine.

When the standalone java file is used as the client, than also it is working fine.
