In MZ's notes, there is a question:
"Which SAAJ type is used to present
SOAP message headers block?"
I hesitate between the options of javax.xml.soap.SOAPPart and javax.xml.soap.SOAPHeaderElement
The right option given in MZ's notes is SOAPPart because of this
But the question is asking for header block. I think the right answer should be SOAPHeaderElement.
For example,
I think if we want to retrieve <wsse:Security> header block content, we should use SOAPHeaderElement instead.
