According to the Web Services Addressing 1.0 specification the format for an Action is (non-fault case):
[target namespace][delimiter][port type name][delimiter][input|output name]
The following definition of delimiter is supplied:
"is ":" when the [target namespace] is a URN, otherwise "/"."
I have a WSDL with the following relevant values:
target namespace - urn:xyz/BLAH
port type name - BlahServicePortType
input name - CountStuffRequest
I would expect CXF to generate the action:
However it appears to use a dot ('.') to delimit the fields:
I will dig around the cxf-rt-ws-addr module to see if I can narrow this down further...
