how to determine wsdl version?

how to determine which wsdl version is used by looking at wsdl xml?
is there any annotation to switch wsdl version in JAX-WS end point?

Hi!
To determine which version a WSDL is of, take a look at the namespace in the <description> element:
WSDL 2.0: xmlns="http://www.w3.org/ns/wsdl"
WSDL 1.2: xmlns="http://schemas.xmlsoap.org/wsdl/"

Regarding your second, question: I am not entirely sure that JAX-WS indeed supports WSDL 2.0. Perhaps someone else can enlighten us.
Best wishes!

Thanks Ivan, I think you're referring to definitions node.

Ah, you caught me! :-)
Of course I was referring to the <definitions> node, even though I wrote the <description> element.
Thanks for pointing this error out!
