Generating Interfaces 

Use

Once the service endpoint interfaces are generated, they schema-mapped classes are used as parameters in these interfaces. These interfaces are the Java representation of this Web service interface. For Web services, where input and output parameters are present, holder classes are generated in the holders sub-package of the root package, according to the JAX-RPX specification. Java classes for service-checked exceptions are also generated. These classes support service-specific exceptions and their automatic deserialization from the transport layer.
