Registries for Web Services
As you saw on Day 3, “Naming and Directory Services,” naming and directory services are an important part of any distributed environment. J2EE uses JNDI as a way of accessing information about application resources and the location of remote services, such as EJBs and databases.
Because Web Services also operate in a distributed environment, Web Service-oriented naming and directory services are required. In fact, the scope of such services is broader under the Web Services model than under J2EE, because the service will hold organizational and business information as well as Web Service metadata and location information. In Web Service terms, the place to find this information is called a registry or repository.
