>             Project: Camel
>          Issue Type: Bug
>          Components: camel-soap
>    Affects Versions: 2.12.0
>            Reporter: Ondrej Fischer
>            Priority: Minor

> If an interface to be used as SOAP service interface is configured to have parameters wrapped in a request wrapper element (eg. using @RequestWrapper),
> then an attempt to invoke a its method will throw NPE:
> {code}
> java.lang.NullPointerException
> 	at org.apache.camel.dataformat.soap.name.ServiceInterfaceStrategy.findQNameForSoapActionOrType(ServiceInterfaceStrategy.java:207)
> 	at org.apache.camel.dataformat.soap.SoapJaxbDataFormat.createContentFromObject(SoapJaxbDataFormat.java:208)
> 	at org.apache.camel.dataformat.soap.Soap11DataFormatAdapter.doMarshal(Soap11DataFormatAdapter.java:77)
> 	at org.apache.camel.dataformat.soap.SoapJaxbDataFormat.marshal(SoapJaxbDataFormat.java:141)
> 	at org.apache.camel.processor.MarshalProcessor.process(MarshalProcessor.java:59)
> {code}
> The reason for this is sequence of following:
> # The ServiceInterfaceStrategy is creating a mapping of methods to MethodInfo.
> # In case of RequestWrapper, the wrapper class is used as a single input TypeInfo, and no TypeInfo is being held for the real parameters.
> # At method invocation, it tries to lookup the TypeInfo in the MethodInfo, but for the real parameter class, and it only contains mapping for the request wrapper. So it fails with NPE.
