How can I resolve the binding failed error in doing wsdl2java - web-services

Question

I am trying to (re)generate code again from a preexisting WSDL. I am not able to use wsimport as it is giving binding failed error. So I tried WSDL validator from CXF. It gives this error. Please see below for my WSDL.
WSDLValidator Error :
Summary: Failures: 1, Warnings: 0
<<< ERROR!
Part <scheduledJob> in Message <{http://webservices.jobs.batch.prompt.com/}ImmJobWSIF_getScheduledJobResponse> referenced Type <{http://webservices.jobs.batch.prompt.com/}ScheduledJob> can not be found in the schemas
Here is the WSDL. Inline schema looks good comparing to some online schemas. I have no clue.
