If you are using the CAS WSDL client stubs provided with the Content Acquisition System, make any changes listed in the Required Changes chapter.
The WSDL namespace has changed in this release. If you are using a WSDL tool to generate stubs, you need to re-generate new CAS WSDL client stubs for CasCrawler, RecordStore, and the ComponentInstanceManager, and then make any changes listed in the Required Changes chapter. For details, see "Generating client stubs for the CAS Web Services" in the Endeca CAS API Guide.
