Generating client web services from Onvif wsdl file

Question

I'm trying to create the client web services from the Onvif standard wsdl file located here. After I pass through all steps in Eclipse wizard using Apache CFX, I get this output:

Loading FrontEnd jaxws ...
Loading DataBinding jaxb ...

I'm new to web services. Can anybody explain me what is the problem and what should I do to solve it?

Answer 1

Finally, I managed to find a workaround to my scenario:

Instead of generating Java classes through Eclipse, I did it directly through CLI, with the command suggested in apache-cfx tutorial. After this I imported generated files in my Eclipse project. For those who need to dig more on this issue, here I have a response to a very similar question.

Hope to be useful for someone.
