Running the Client Examples

The simple client programs provided with this tutorial can be run from the command line. You can modify them to suit your needs. They allow you to specify the Java WSDP Registry Server for queries and updates. (To install the Registry Server, follow the instructions in Preliminaries: Getting Access to a Registry.

The examples, in the <INSTALL>/javaeetutorial5/examples/jaxr/simple/src/ directory, are as follows:

JAXRQuery.java shows how to search a registry for organizations.

JAXRQueryByNAICSClassification.java shows how to search a registry using a common classification scheme.

JAXRQueryByWSDLClassification.java shows how to search a registry for web services that describe themselves by means of a WSDL document.

JAXRPublish.java shows how to publish an organization to a registry.

JAXRDelete.java shows how to remove an organization from a registry.

JAXRSaveClassificationScheme.java shows how to publish a classification scheme (specifically, a postal address scheme) to a registry.

JAXRPublishPostal.java shows how to publish an organization with a postal address for its primary contact.

JAXRQueryPostal.java shows how to retrieve postal address data from an organization.

JAXRDeleteScheme.java shows how to delete a classification scheme from a registry.

JAXRPublishConcept.java shows how to publish a concept for a WSDL document.

JAXRPublishHelloOrg.java shows how to publish an organization with a service binding that refers to a WSDL document.

JAXRDeleteConcept.java shows how to delete a concept.

JAXRGetMyObjects.java lists all the objects that you own in a registry.

The <INSTALL>/javaeetutorial5/examples/jaxr/simple/ directory also contains the following:

A build.xml file for the examples

A JAXRExamples.properties file, in the src subdirectory, that supplies string values used by the sample programs

A file called postalconcepts.xml that serves as the taxonomy file for the postal address examples

You do not have to have the Application Server running in order to run most of these client examples. You do need to have it running in order to run JAXRPublishConcept.java and JAXRPublishHelloOrg.java.

Before You Compile the Examples

Before you compile the examples, edit the file <INSTALL>/javaeetutorial5/examples/jaxr/simple/src/JAXRExamples.properties as follows.

If the Application Server where you installed the Registry Server is running on a system other than your own or if it is using a nondefault HTTP port, change the following lines:

query.url=http://localhost:8080/RegistryServer/ publish.url=http://localhost:8080/RegistryServer/ ... link.uri=http://localhost:8080/hello-jaxws/hello?WSDL ... wsdlorg.svcbnd.uri=http://localhost:8080/hello-jaxws/hello

Specify the fully qualified host name instead of localhost, or change 8080 to the correct value for your system.

(Optional) Edit the following lines, which contain empty strings for the proxy hosts, to specify your own proxy settings. The proxy host is the system on your network through which you access the Internet; you usually specify it in your Internet browser settings.

## HTTP and HTTPS proxy host and port http.proxyHost= http.proxyPort=8080 https.proxyHost= https.proxyPort=8080

The proxy ports have the value 8080, which is the usual one; change this string if your proxy uses a different port.

Your entries usually follow this pattern:

http.proxyHost=proxyhost.mydomain http.proxyPort=8080 https.proxyHost=proxyhost.mydomain https.proxyPort=8080

You need to specify a proxy only if you want to specify an external link or service binding that is outside your firewall.

Feel free to change any of the organization data in the remainder of the file. This data is used by the publishing and postal address examples.

You can edit the src/JAXRExamples.properties file at any time. The Ant targets that run the client examples will use the latest version of the file.

Compiling the Examples

To compile the programs, go to the <INSTALL>/javaeetutorial5/examples/jaxr/simple/ directory. A build.xml file allows you to use the following command to compile all the examples:

This command uses the default target, which performs the compilation. The Ant targets create subdirectories called build and dist.

Running the Examples

Getting a List of Your Registry Objects

To get a list of the objects you own in the registry--organizations, classification schemes, and concepts--run the JAXRGetMyObjects program by using the run-get-objects target:

It is a good idea to run this program first to make sure the Registry Server is running properly. The first time you access the Registry Server, you are likely to see a runtime error. If you run the program a second time, the program should run correctly.

Because you are logged in as the default user, testuser, you will see a list of all the objects in the registry when you run this program. Most of these objects are classification schemes.

Running the JAXRPublish Example

To run the JAXRPublish program, use the run-publish target with no command-line arguments:

The program output displays the string value of the key of the new organization.

After you run the JAXRPublish program but before you run JAXRDelete, you can run JAXRQuery to look up the organization you published.

Note: When you run any program that publishes an object to the registry, a runtime warning appears in the server log (a com.sun.xnode.XNodeException). It is safe to ignore this warning.

Running the JAXRQuery Example

To run the JAXRQuery example, use the Ant target run-query. Specify a query-string argument on the command line to search the registry for organizations whose names contain that string. For example, the following command line searches for organizations whose names contain the string "coffee" (searching is not case-sensitive):

Running the JAXRQueryByNAICSClassification Example

After you run the JAXRPublish program, you can also run the JAXRQueryByNAICSClassification example, which looks for organizations that use the All Other Specialty Food Stores classification, the same one used for the organization created by JAXRPublish. To do so, use the Ant target run-query-naics:

Running the JAXRDelete Example

To run the JAXRDelete program, specify the key string displayed by the JAXRPublish program as input to the run-delete target:

Publishing a Classification Scheme

To publish organizations with postal addresses, you must first publish a classification scheme for the postal address.

To run the JAXRSaveClassificationScheme program, use the target run-save-scheme:

Running the Postal Address Examples

Open the file src/postalconcepts.xml in an editor.

Wherever you see the string uuid-from-save, replace it with the UUID string returned by the run-save-scheme target (including the uuid: prefix).

For a given registry, you only need to publish the classification scheme and edit postalconcepts.xml once. After you perform those steps, you can run the JAXRPublishPostal and JAXRQueryPostal programs multiple times.

Run the JAXRPublishPostal program. Specify the string you entered in the postalconcepts.xml file, including the uuid: prefix, as input to the run-publish-postal target:

ant -Duuid-string=uuidstring run-publish-postal

The uuidstring would look something like this:

uuid:938d9ccd-a74a-4c7e-864a-e6e2c6822519

The program output displays the string value of the key of the new organization.

Run the JAXRQueryPostal program. The run-query-postal target specifies the postalconcepts.xml file in a <sysproperty> tag.

As input to the run-query-postal target, specify both a query-string argument and a uuid-string argument on the command line to search the registry for the organization published by the run-publish-postal target:

ant -Dquery-string=coffee -Duuid-string=uuidstring run-query-postal

The postal address for the primary contact will appear correctly with the JAXR PostalAddress methods. Any postal addresses found that use other postal address schemes will appear as Slot lines.

Deleting a Classification Scheme

To delete the classification scheme you published after you have finished using it, run the JAXRDeleteScheme program using the run-delete-scheme target:

Publishing a Concept for a WSDL Document

The JAXRPublishConcept program publishes the location of the WSDL document for the JAX-WS Hello service described in Creating a Simple Web Service and Client with JAX-WS (page 496). Normally, you deploy the service before you publish the location of the WSDL document. However, this program runs correctly whether or not the service is deployed.

To run the JAXRPublishConcept program, use the Ant target run-publish-concept:

The program output displays the UUID string of the new specification concept, which is named HelloConcept. You will use this string in the next section.

After you run the JAXRPublishConcept program, you can run JAXRPublishHelloOrg to publish an organization that uses this concept.

Publishing an Organization with a WSDL Document in Its Service Binding

To run the JAXRPublishHelloOrg example, use the Ant target run-publish-hello-org. Specify the string returned from JAXRPublishConcept (including the uuid: prefix) as input to this target:

The program output displays the string value of the key of the new organization, which is named Hello Organization.

After you publish the organization, run the JAXRQueryByWSDLClassification example to search for it. To delete it, run JAXRDelete.

Running the JAXRQueryByWSDLClassification Example

To run the JAXRQueryByWSDLClassification example, use the Ant target run-query-wsdl. Specify a query-string argument on the command line to search the registry for specification concepts whose names contain that string. For example, the following command line searches for concepts whose names contain the string "helloconcept" (searching is not case-sensitive):

Deleting a Concept

To run the JAXRDeleteConcept program, specify the UUID string displayed by the JAXRPublishConcept program as input to the run-delete-concept target:

Do not delete the concept until after you have deleted any organizations that refer to it.

Other Targets

To remove the build and dist directories and the class files, use the command
