WS-Discovery with WSO2 Carbon

WS-Discovery defines a protocol to locate web services on a network, more specifically in a SOA. The newest release of WSO2 Carbon platform (version 3.0.0) provides a complete implementation of the WS-Discovery managed mode . This post demonstrates an end-to-end workflow of WS-Discovery support in WSO2 Carbon. With WS-Discovery components for WSO2 Carbon, any Carbon server can act as a WS-Discovery client, a WS-Discovery proxy or a WS-Discovery target service. We will use three products from WSO2 Carbon product suite, namely WSO2 Governance Registry (G-reg), WSO2 ESB and WSO2 WSAS. WSO2 G-reg acts as the central repository in which the discovered services and the related meta data are stored. WSO2 WSAS is used to host the target services. WSO2 ESB participates in the scenario as a discovery client which looks for services and endpoints. Lets start with setting up the environment. Pre-requistes: Download WSO2 Governance Registry-3.5.0 , WSO2 WSAS-3.2.0
