-------------------------------------
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.
