How to set wsdl inner schema to Jaxb2Marshaller to validate each post i wold make?
I\'m consuming a SOAP webservice where I have to validate every xml post before call it.
So I\'m using:
- The cxf-codegen-plugin to generate
-
finally I found an implementation that works for me.
The idea is:
- to extract the embedded schema's from the wsdl,
- configure each schema namespace,
- adding all posible namespaces non defined yet in it but that are defined on <wsdl:definition> tag,
- configure each schema import and locations,
- store each schema into an implementing class of spring's Resource interface,
- store all of them into an Resource array
- and pass this array to the Jaxb2Marshaller through setSchema[s], instead of setSchema (as I have been doing).
Based on the question, I had to modify the XxxxMarshallerProperties class and the applicationContext-xxxx-base.xml files, only.
XxxxMarshallerProperties:
