Answer 1

This error is telling you that your class name is incorrect somewhere.

Quick Tip! - Scroll down and read the portion right below the error message that says "Caused by:". It will give you more insight.

Check your cxf-servlet.xml file to make sure the fully qualified class name actually exists in the specified package.

Also, check your classes that are annotated with @WebService to make sure that your endpointInterface parameter is correct.

Hope this helps.

Answer 2

This error can happen when you are using invalid class in cxf-servlet.xml. So make sure that the value for class is correct in the cxf-servlet.xml. You can find this file inside src>>main>>webapp>>WEB-INF directory.
