Oracle9iAS Wireless device transformers convert the XML received from the Web service adapter to the markup language appropriate for the requesting wireless device. Oracle9iAS Wireless provides two types of transformers:
|
| Generic service transformers for languages such as WML. Generic service transformers convert the Oracle 9iAS Wireless-compliant XML to a generic WML format that works on any WAP-compliant wireless phone. |
| Device-specific transformers which are optimized for a specific device. For instance, instead of using the generic WML transformer, the developer may use a device-specific transformer that exploits the device characteristics of a specific phone. |
