Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Overloading Web Service Methods

SOAP and WSDL do not provide good support for overloading methods. Consequently, Apex does not allow two methods marked with the webservice keyword to have the same name. Web service methods that have the same name in the same class generate a compile-time error.
