Web Service is one of many well-defined extension points supported by the WSO2 Governance Registry. Read more on Supported Extension Points for a complete list of extension points supported by WSO2 Governance Registry. |
This sample explains how to use the Governance API of WSO2 Governance Registry to create a simple webservice which is capable of looking up service endpoints. WSO2 Governance Registry contains an Apache Axis2 based runtime as a part of the WSO2 Carbon Framework. You can deploy web services on this runtime, which can be used as internal endpoints to receive notifications generated on the WSO2 Governance Registry. We will be reusing the code of the Handler Sample in this example. This sample requires Apache Maven. See Installing Apache Maven for Governance Registry on Windows or Installing Apache Maven for Governance Registry on Linux. This example also explains how to use soapUI, which is a very useful tool for testing web services.
