The JAXR Inquiry and Publishing APIs





The JAXR Inquiry and Publishing APIs

In Part III: UDDI you learned about the UDDI Inquiry and Publishing APIs, two sets of SOAP operations designed for searching for and saving data in a UDDI registry. The JAXR API hides many of the Inquiry and Publishing operations behind compact and expressive Java code. For example, if you navigate from an Organization to its WSDL Concept, the underlying JAXR implementation may send several inquiry messages to the UDDI registry without your knowing—or needing to know. The JAXR implementation creates and sends the SOAP messages automatically, to construct a complete information model so that the registry is easier for you to peruse.[1]

[1] It's not specified whether the query messages are done all at once, or lazily, as needed. I suspect the latter in most cases, but JAXR is not an API in which performance is really important, so I'm not sure it matters which strategy is used.

The two major sections of this chapter show the mappings between the JAXR API and the UDDI Inquiry and Publishing APIs.
