UDDI Involves Teamwork
The examples in this chapter use Microsoft’s UDDI site, but UDDI Web sites are supported by a group of industry leaders (including HP, IBM, Microsoft, and SAP), who formed a consortium to maintain the UDDI registry system. This system is a database of businesses and the URL of the Web Services they offer, any available WSDL files, and provided business information. Each of the vendors replicates the entries it receives back to the others. Regardless of where you enter the information about your Web Service, it should show up on the other sites as well. Figure 5.7 demonstrates the replication among the different UDDI sites.
The current working version of UDDI is Version 1. Table 5.1 displays the URLs of the Web sites and the vendors maintaining Web sites for this version.
| Vendor | URL |
|---|---|
| Microsoft | http://uddi.microsoft.com/ |
| IBM | http://www-3.ibm.com/services/uddi/find |
UDDI Version 2 should soon be available for production; as of this writing the UDDI Version 2 sites are in Beta. The main difference between the two different versions seems to be an improved Graphical User Interface (GUI), along with better security. Table 5.2 shows the URLs and their supporting vendor for Beta Web Sites demonstrating UDDI Version 2. Data in these Beta UDDI Web sites may not be saved when they go operational.
| Vendor | URL |
|---|---|
| Microsoft | https://uddi.rte.microsoft.com/search/frames.aspx |
| IBM | https://www3.ibm.com/services/uddi/v2beta/protect/registry.html |
| Hewlet Packard | https://uddi.hp.com/uddi/index.jsp |
| SAP | https://websmp201.sap-ag.de/~form/uddi_discover |
| Note | Notice that the URLs for UDDI Version 2 Beta use “HTTPS” instead of “HTTP.” This means that your searches of these sites are encrypted, preventing others from knowing what you searched for. This is the same protection you receive at many E-commerce sites when you make a credit card transaction. |
