Generating Derived Types

When a WSDL or schema includes derived types, you must choose the types that you want to include in the SOAP message.

For example, the WSDL defines a base type AddressType. The WSDL also contains a USAddressType and a UKAddressType that are the derived AddressTypes.

Each type contains the following elements:

AddressType: street, city

USAddressType (extends AddressType): state, zipCode

UKAddressType (extends AddressType): postalCode, country

When you choose a USAddressType in the Operation area, the Developer tool creates a group for the USAddressType element in the SOAP message. The group includes the street and city from the base address and the state and zipCode for the USAddress. Derived types that extend base types always include the elements from the base type.

If you choose all of the available derived types for the SOAP messsage, the Developer tool creates groups similar to the following in the SOAP hierarchy:

 Address
   Address: Address
     Street
     City

   Address:USAddressType
      Street
      City
      State
      ZipCode

   Address: UKAddressType
      Street
      City
      PostalCode
      Country

You need to define input port groups for Address, USAddress, and UKAddress.
