I am able to generate a client for the web service in synch mode. I am using the JAX-WS framework.
When I check the asynch mode for client, I get the following error.

smakam ,

Sorry that you are seeing this issue. We have a PR filed for the same issue when the wsdl file path has spaces in it and the dev team is looking into it.

Can you check if your wsdl file path has spaces in it ? As a workaround , move the same wsdl to a location that does not contain spaces in its path.

Let us know how it works for you.

The problem is resolved when I removed the space in the directory path to the WSDL file.

thanks

smakam ,

Glad that it is working.
Do let us know if you have any other issues.
