Oracle ADF integrates seamlessly with web services, enabling applications to exchange data and functionality with external systems. Here's how ADF works with web services:
1. Consuming Web Services :
- Data Controls:
- ADF provides data controls that can represent web services as data sources.
- This allows developers to drag and drop web service operations onto their user interface, treating them like any other data control.
- Web Service Proxies:
- ADF can generate Java proxies for web services, allowing applications to invoke web service operations programmatically.
- This simplifies the process of making web service calls from within ADF applications.
- SOAP and REST Support:
- ADF supports both SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) web services, providing flexibility in integrating with various external systems.
2. Exposing ADF Business Services as Web Services :
- Service Data Objects (SDOs):
- ADF Business Components can be exposed as web services using SDOs, which provide a data-centric approach to web service development.
- Web Service Deployment:
- ADF provides tools for deploying ADF Business Components as web services, making them accessible to external applications.
- JAX-WS and JAX-RS:
- ADF leverages Java API for XML Web Services (JAX-WS) for SOAP web services and Java API for RESTful Web Services (JAX-RS) for REST web services.
3. Data Transformation and Mapping :
- Data Mapping:
- ADF provides tools for mapping data between web service payloads and ADF Business Components.
- This allows for seamless data exchange between different systems, even if they use different data formats.
- XML Processing:
- ADF's XML processing capabilities enable applications to transform and manipulate XML data exchanged with web services.
4. Security :
- Web Service Security:
- ADF supports various web service security standards, such as WS-Security, to protect web service communications.
- This ensures that sensitive data is protected from unauthorized access.
- Authentication and Authorization:
- ADF can handle authentication and authorization for web service calls, ensuring that only authorized users can access web service operations.
