an existing registry provider, such as a UDDI or ebXML registry. The implemen-
tation of JAXR in the Application Server itself is an example of a JAXR pro-
vider.

The Application Server provides JAXR in the form of a resource adapter using
the Java EE Connector architecture. The resource adapter is in the directory

<JAVAEE_HOME>/lib/install/applications/jaxr-ra

(

<JAVAEE_HOME>

the directory where the Application Server is installed.)

This tutorial includes several client examples, which are described in Running
the Client Examples (page 199), and a Java EE application example, described
in Using JAXR Clients in Java EE Applications (page 206). The examples are in
the directory

<INSTALL>/javaeetutorial5/examples/jaxr/

. (

<INSTALL>

the directory where you installed the tutorial bundle.) Each example directory
has a

build.xml

file (which refers to a

targets.xml

file) and a

build.proper-

ties

file in the directory

<INSTALL>/javaeetutorial5/examples/jaxr/com-

mon/

Establishing a Connection

The first task a JAXR client must complete is to establish a connection to a regis-
try. Establishing a connection involves the following tasks:

· Preliminaries: Getting access to a registry

· Creating or looking up a connection factory

· Creating a connection

· Setting connection properties

· Obtaining and using a

RegistryService

object

Preliminaries: Getting Access to a Registry

To use the Java WSDP Registry Server, a private UDDI version 2 registry, you
need to download and install Java WSDP 1.5 and then to install the Registry
Server in the Application Server.

To download Java WSDP 1.5, perform these steps:

1. Go to the following URL:

http://java.sun.com/webservices/downloads/1.5/index.html

2. Under Java Web Services Developer Pack v1.5, click Download.
