Create web service client cross SSL with eclipse

When creating web service cross SSL using eclipse, it occuss some error like below:

And it can't build the client source from this way.
To solve this problem, there are two ways to achieve it.
1. Connection wsdl using HTTP protocol.
and it seems to be a stupid way when this web service only provide HTTPS protocol.
2. Save the wsdl file from the url and use local file to create client.
a. Save the wsdl as a local file. (Such as myService.wsdl)
b. Copy the wsdl file to the project.
c. right click the wsdl file -> [ Web Services ] -> [ Generate Client ]
d. Congratulations. You got it.
