I have to tool to generate soap requests and it can do so in two ways. Either generating the request beginning with:
<soapenv:Envelope xmlns:ns="http://…" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
or with:
<soap:Envelope xmlns:ns="http://…" xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
I suspect that one is the current technique and the other is the legacy technique. But since only one has something resembling a date in the url I can't figure out which is.
Which of the two it the current version to be used for new requests?
It uses namespace as http://schemas.xmlsoap.org/soap/envelope/.
It uses namespace as http://www.w3.org/2003/05/soap-envelope.
Refer links for more details.
Which one should be used for new services?
SOAP1.2 should be used for new services as its latest and greatest, more cleaner and robust. Though now a days trend is more for Restfull Services then SOAP.
