If you want to practice using the uddi registry via jaxr apis then you can even use the locally hosted uddi registry service RI which comes with Sun
Java AS 8.2 (and install jwsdp 1.5+). The registry service is installed as a web application on Sun AS and you can use that to publish and inquire.
The best way to verify that your installation has worked is to see the list of web applications hosted by the server (using AdminConsole of SunAS for example) and if there is one RegistryServer listed then your integration was
successful and you can access the UDDI v2 registry JSE with the URL
http://localhost:<port>/RegistryServer/ (the end slash in the URL is important) or both the publish and query webservice. There's a Registry Browser (a standalone java application) installed with the JWSDP 1.5 installation which can be used to test the connection with the UDDI registry service.
