You can use the UDDI Version 3 Client for Java to access the UDDI Version 3 application programming interfaces (APIs) from Java client code.
The UDDI Version 3 Client for Java is a JAX-RPC Java class library that provides an API that can be used by client programs to interact with a Version 3 UDDI registry. This class library can be used to construct UDDI JAX-RPC objects and to invoke the UDDI Version 3 WebService.
This client also contains an XML Digital Signature utility class called SignatureUtilities, provided to construct and validate Digital Signatures on UDDI elements. See Use of digital signatures with the UDDI registry for full details.
The UDDI Version 3 API supports both UTF-8 and UTF-16 encoding. Internally, UTF-16 characters are stored as UTF-8 characters. This behavior is transparent to the user application.

The UDDI Version 3 client provides port types which map onto the UDDI Version 3 SOAP inquiry, publish, custody transfer and security APIs. These APIs are protected as described in Access control for UDDI registry interfaces. A client program using the UDDI Version 3 client should get the appropriate port type for the request that is to be issued (such as the UDDI_Publication_PortType for a save_business request). If the role mappings are such that the request will require a WebSphere Application Server authenticated user ID, the client program should pass the user ID and password by setting the relevant properties on the JAX-RPC stub for that port.
These classes contain details on how to compile and execute the samples.
