Failing to Regenerate Web Services Connector created in Older Version(8.2)

Hi All,

In my project all Webservice connectors were created in version Webmethods version 8.2.
Now my project is moved to Webmethods version : 9.7
Now after adding a new operation in Web Service Descriptor , I tried to regenerate my Web Service connectors to updated the changes.

But on regenerating WSC , my CAF project is showing errors (as if many Java classes are absent)
I think on regenerating Web Service .It is not deleting and creating all WSC again.

Can anyone please suggest how can I resolve this issue.
Thanks,
Anand

Which end point are you pointing for regenerating? Have you validated ws-clients.xml file?
