# 21.2 Creating Web Service Data Controls

The most common way of using web services in an application developed using JDeveloper's ADF framework is to create a data control for an external web service, and a usual reason for this is to add functionality that is readily available as a web service but which would be time consuming to develop with the application, or to access an application that runs on a different architecture.

Also, you can re-use components created by the ADF framework to make them available as web services for other applications to access.

## 21.2.1 How to Create a Web Service Data Control

JDeveloper allows you to create a data control for an existing web service using just the WSDL for the service. You can browse to a WSDL on the local file system, locate one in a UDDI registry, or enter the WSDL URL directly.

Note: If you are working behind a firewall and you want to use a web service that is outside the firewall, you must configure the Web/Browser Proxy settings in JDeveloper. Refer to the JDeveloper online help for more information.

To create a web service data control:

1. In the Application Navigator, right-click an application and choose New.

2. In the New Gallery, expand Business Tier in the Categories tree, and select Web Services.

3. In the Items list, double-click Web Service Data Control.

4. Follow the wizard instructions to complete creating the data control.

Alternatively, you can right-click on the WSDL node in the navigator and select the Create Data Control from the context menu.
