-------------------------------------

             Summary: SoapJaxbDataFormat not handling correctly SOAP action with request wrapper
element
                 Key: CAMEL-6720
                 URL: https://issues.apache.org/jira/browse/CAMEL-6720
             Project: Camel
          Issue Type: Bug
          Components: camel-soap
    Affects Versions: 2.12.0
            Reporter: Ondrej Fischer


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.
