[Venkatesh Rangamani]

Ranchers,
I am using RMH to prepare for SCDJWS. All the examples for JAXR uses IBMs UDDI. But IBM , SAP and Microsoft have shutdown their UDDI registries. How to work with UDDI registries. Are there any public registries available?? or is there tools to create a UDDI registry in my PC ?? If yes please let me know the steps to do so.

Thanks
