A new approach to UDDI and WSDL, Part 4: Publish from Java using the new OASIS UDDI WSDL Technical Note

Use UDDI4J to publish WSDL to UDDI

John Colgrave (colgrave@uk.ibm.com), Senior Software Engineer, IBM United Kingdom Limited
John Colgrave is the architect of the IBM WebSphere UDDI registry and a member of the OASIS UDDI Specifications Technical Committee. He is one of the authors of the new OASIS UDDI Technical Note on using UDDI and WSDL.

Summary:  This is the fourth in a series of articles that outline a new approach to using WSDL and UDDI, as described in a recent OASIS UDDI Technical Note. This article presents an example in which you apply the approach defined in the new Technical Note to publishing from a Java application.

In the first article in this series (see Resources for links to Parts 1, 2, and 3), you learned about a new approach to constructing a UDDI model of a WSDL description. The second article described the types of UDDI query this new approach enables, with examples of several queries given in the form of UDDI V2 API requests. The third presented a more complex example than the one in the Technical Note, including screenshots showing you how to publish the UDDI entities and how to construct the types of query described in the Technical Note and in Part 2.

In this fourth article, you'll see some sample Java code that will publish WSDL descriptions to UDDI programmatically. The fifth article in the series will describe how to write a Java application that can issue the queries described in the other articles in this series, using UDDI4J.

The UDDI registry

The UDDI registry used in this example is an instance of the UDDI implementation that is shipped with IBM® WebSphere® Application Server Network Deployment V5.1.

I added the tModels required by the new Technical Note to the registry, along with the tModel required by WS-I. These tModels are added using the UDDI Utility Tools that are new in Application Server V5.1. The definitions of the Technical Note tModels are shown in Listing 1 in this sidefile.

There are a couple of differences between the definitions in Listing 1 and the definitions given in the Technical Note:

  1. I removed the checked categorization, as the UDDI registry in WebSphere Application Server V5.1 has not been updated to check these category systems in the special way that they require.
  2. I added the IBM-specific keyedReferences necessary to use the custom taxonomy support for the WSDL entity types taxonomy.

The definition of the WS-I tModel is illustrated in Listing 2.

"WS-I Conformance"/>
            </categoryBag>
        </tModel>
    </promote:tModels>
</promote:uddiEntities>

I also added a custom taxonomy for the WSDL entity type category system so that the WSDL entity type can be chosen from the category tree view. Listing 3 illustrates the data for this taxonomy.


Listing 3. Definition of the WSDL entity type taxonomy
wsdltype#root#WSDL Entity Types#root
wsdltype#portType#WSDL portType#root
wsdltype#binding#WSDL binding#root
wsdltype#service#WSDL service#root
wsdltype#port#WSDL port#root

Finally, I added a custom taxonomy for the WS-I conformance taxonomy. Listing 4 illustrates the data for this taxonomy. Note that because taxonomy values are limited to 32 characters, it is not possible to include the entire string defined by the WS-I Basic Profile, as that string is 34 characters long. The remaining 2 characters have to be supplied manually after the value has been chosen.

Level of abstraction

The API presented here is at a fairly low level of abstraction. For example, the caller must be aware that a portType is mapped to a tModel, and must know the various keys. A higher-level API that reads a WSDL file and automatically publishes the UDDI model corresponding to it could be built on top of this API, but discussion of such an API is beyond the scope of this article.

Structure of the API

The API is structured as a single Java class that is a wrapper around an instance of the UDDI4J UDDIProxy class. An instance of the Publish class is constructed from an instance of the UDDIProxy class and the appropriate authInfo value to use for publishing.

The Publish class provides methods to publish each of the entities used in the WSDL Technical Note. There are two methods for each type of entity. The first takes as parameters only the information required by the WSDL Technical Note. The second takes, in addition, an instance of the corresponding UDDI4J type; this instance can be used to pass in additional information. For example, in the case of the publish_binding_tModel() method, the extra parameter tModel is used to pass any additional information that should be added to the binding tModel that is published. In the sample, this is used to pass in the WS-I conformance information by passing in a tModel that contains a categoryBag, which in turn contains the WS-I keyedReference.

Details of the API

As already mentioned, the API is a single Java class; its fully-qualified name is uddi.wsdl.v2.publish.Publish, and it has a constructor and eight methods. The class and the constructor are shown in Listing 5.

{
    private final static String WSDL_ENTITY_TYPE_TMODELKEY = 
    "uuid:6e090afa-33e5-36eb-81b7-1ca18373f457";
    private final static String WSDL_ENTITY_TYPE_KEYNAME = 
    "WSDL entity type";
    private final static String XML_NAMESPACE_TMODELKEY = 
    "uuid:d01987d1-ab2e-3013-9be2-2a66eb99d824";

    private final static String UDDI_TYPES_TMODELKEY =

    "XML local name";

    private String authInfo;
    private UDDIProxy proxy;
    
    public Publish(UDDIProxy proxy, String authInfo)
    {
        this.proxy = proxy;
        this.authInfo = authInfo;
    }
}

The first parameter is an instance of a UDDI4J proxy, which is assumed to be configured with the appropriate URLs and so on. The second parameter is the authInfo string to be used when making UDDI4J calls to publish to the UDDI registry.

The class's eight methods are made up of four pairs of methods, one pair for each of the different UDDI entities that can be published:

  • publish_portType_tModel()
  • publish_binding_tModel()
  • publish_service()
  • publish_bindingTemplate()

As mentioned above, the difference between the methods of each pair is that one method takes an instance of the appropriate UDDI4J type as an extra parameter. The method that does not take the extra parameter creates a new instance of the appropriate type and then calls the method that does take the extra parameter. The method that takes the extra parameter then generally adds the information required by the WSDL Technical Note to the instance passed in and publishes the instance to the UDDI registry represented by the UDDI4J proxy. The following sections detail each of these pairs of methods.

publish_portType_tModel()

The publish_portType_tModel() method that takes the extra parameter is shown in Listing 6.


Listing 6. Signature of the publish_portType_tModel() method with the extra parameter
public TModelDetail publish_portType_tModel(
        TModel tModel,
        String namespaceName,
        String portTypeName,
        String url)
        throws UDDIException, TransportException
    {
        // Overwrite any supplied name.
        tModel.setName(portTypeName);

        // Overwrite any supplied overviewDoc.
        OverviewDoc overviewDoc = new OverviewDoc();
        overviewDoc.setOverviewURL(url);
        tModel.setOverviewDoc(overviewDoc);

        // Add keyedReferences required by Technical Note.
        CategoryBag categoryBag = tModel.getCategoryBag();
        if (categoryBag == null)
        {
            categoryBag = new CategoryBag();
            tModel.setCategoryBag(categoryBag);
        }
        KeyedReference wsdlEntityTypeKR =
            new KeyedReference(
                WSDL_ENTITY_TYPE_KEYNAME,
                "portType",
                WSDL_ENTITY_TYPE_TMODELKEY);
        categoryBag.add(wsdlEntityTypeKR);
        KeyedReference xmlNamespaceKR =
            new KeyedReference(
                XML_NAMESPACE_KEYNAME,
                namespaceName,
                XML_NAMESPACE_TMODELKEY);
        categoryBag.add(xmlNamespaceKR);

        Vector tModels = new Vector();
        tModels.add(tModel);
        TModelDetail tModelDetail = proxy.save_tModel(authInfo, tModels);
        return tModelDetail;
    }

The publish_portType_tModel() method does the following:

  1. Sets the tModel name to be the value of the portTypeName parameter, overwriting any name supplied as part of the tModel parameter.
  2. Replaces any supplied overviewDoc with a new overviewDoc that has an overviewURL of the value of the uri parameter.
  3. Creates a categoryBag if one was not supplied in the tModel parameter and adds two keyedReferences to it: one for the WSDL entity type taxonomy and one for the XML namespace taxonomy, using the value of the namespaceName parameter as the namespace name.

The publish_portType_tModel() method that does not take an extra parameter is shown in Listing 7.


Listing 7. publish_portType_tModel() method without an extra argument
public TModelDetail publish_portType_tModel(
        String namespaceName,
        String portTypeName,
        String url)
        throws UDDIException, TransportException
    {
        TModel tModel = new TModel();
        tModel.setTModelKey("");
        return publish_portType_tModel(tModel, namespaceName, portTypeName, url);
    }

publish_binding_tModel()

The version of this method that takes an additional parameter is shown in Listing 8.


Listing 8. Method to publish a binding tModel, with additional information
public TModelDetail publish_binding_tModel(
        TModel tModel,
        String namespaceName,
        String bindingName,
        String url,
        String portTypeTModelKey,
        String protocolTModelKey,
        String transportTModelKey)
        throws UDDIException, TransportException
    {
        // Overwrite any supplied name.
        tModel.setName(bindingName);

        // Overwrite any supplied overviewDoc.
        OverviewDoc overviewDoc = new OverviewDoc();
        overviewDoc.setOverviewURL(url);
        tModel.setOverviewDoc(overviewDoc);

        // Add keyedReferences required by Technical Note.
        CategoryBag categoryBag = tModel.getCategoryBag();
        if (categoryBag == null)
        {
            categoryBag = new CategoryBag();
            tModel.setCategoryBag(categoryBag);
        }
        KeyedReference wsdlEntityTypeKR =
            new KeyedReference(
                WSDL_ENTITY_TYPE_KEYNAME,
                "binding",
                WSDL_ENTITY_TYPE_TMODELKEY);
        categoryBag.add(wsdlEntityTypeKR);
        KeyedReference xmlNamespaceKR =
            new KeyedReference(
                XML_NAMESPACE_KEYNAME,
                namespaceName,
                XML_NAMESPACE_TMODELKEY);
        categoryBag.add(xmlNamespaceKR);
        KeyedReference wsdlPortTypeReferenceKR =
            new KeyedReference(
                WSDL_PORTTYPE_REFERENCE_KEYNAME,
                portTypeTModelKey,
                WSDL_PORTTYPE_REFERENCE_TMODELKEY);
        categoryBag.add(wsdlPortTypeReferenceKR);
        KeyedReference wsdlSpecKR =
            new KeyedReference(
                UDDI_TYPES_KEYNAME,
                "wsdlSpec",
                UDDI_TYPES_TMODELKEY);
        categoryBag.add(wsdlSpecKR);
        KeyedReference protocolKR =
            new KeyedReference(
                PROTOCOL_CATEGORIZATION_KEYNAME,
                protocolTModelKey,
                PROTOCOL_CATEGORIZATION_TMODELKEY);
        categoryBag.add(protocolKR);
        if (transportTModelKey != null)
        {
            KeyedReference transportKR =
                new KeyedReference(
                    TRANSPORT_CATEGORIZATION_KEYNAME,
                    transportTModelKey,
                    TRANSPORT_CATEGORIZATION_TMODELKEY);
            categoryBag.add(transportKR);
        }

        Vector tModels = new Vector();
        tModels.add(tModel);
        TModelDetail tModelDetail = proxy.save_tModel(authInfo, tModels);
        return tModelDetail;
    }

The publish_binding_tModel() method does the following:

  1. Sets the tModel name to be the value of the bindingName parameter, overwriting any name supplied as part of the tModel parameter.
  2. Replaces any supplied overviewDoc with a new overviewDoc that has an overviewURL of the value of the uri parameter.
  3. Creates a categoryBag if one was not supplied in the tModel parameter and adds the appropriate keyedReferences to it. The WSDL entity type keyedReference has a value of binding. The XML namespace keyedReference has a value that is the value of the namespaceName parameter. The portType reference keyedReference has a value that is the value of the portTypeTModelKey parameter. The tModel is categorized with the value wsdlSpec. The protocol categorization keyedReference has a value that is the value of the protocolTModelKey parameter. If the value of the transportTModelKey parameter is not null, then a transport categorization keyedReference is added; its value is the value of the transportTModelKey parameter.

The version of the method to publish a binding tModel that takes as parameters only the information required by the Technical Note is shown in Listing 9.


Listing 9. Method to publish a binding tModel, without any additional information
public TModelDetail publish_binding_tModel(
        String namespaceName,
        String bindingName,
        String url,
        String portTypeTModelKey,
        String protocolTModelKey,
        String transportTModelKey)
        throws UDDIException, TransportException
    {
        TModel tModel = new TModel();
        tModel.setTModelKey("");
        return publish_binding_tModel(tModel, namespaceName, bindingName, 
        url, portTypeTModelKey, protocolTModelKey, transportTModelKey);
    }

publish_service()

The publish_service() method that takes the extra parameter is shown in Listing 10.


Listing 10. publish_service() method with extra parameter
public ServiceDetail publish_service(
        BusinessService service,
        String namespaceName,
        String serviceName)
        throws UDDIException, TransportException
    {
        // Add name only if the user has not supplied one.
        Name defaultName = service.getDefaultName();
        if (defaultName == null)
        {
            defaultName = new Name(serviceName);
            service.setDefaultName(defaultName);
        }

        // Add keyedReferences required by Technical Note.
        CategoryBag categoryBag = service.getCategoryBag();
        if (categoryBag == null)
        {
            categoryBag = new CategoryBag();
            service.setCategoryBag(categoryBag);
        }
        KeyedReference wsdlEntityTypeKR =
            new KeyedReference(
                WSDL_ENTITY_TYPE_KEYNAME,
                "service",
                WSDL_ENTITY_TYPE_TMODELKEY);
        categoryBag.add(wsdlEntityTypeKR);
        KeyedReference xmlNamespaceKR =
            new KeyedReference(
                XML_NAMESPACE_KEYNAME,
                namespaceName,
                XML_NAMESPACE_TMODELKEY);
        categoryBag.add(xmlNamespaceKR);
        KeyedReference xmlLocalNameKR =
            new KeyedReference(
                XML_LOCAL_NAME_KEYNAME,
                serviceName,
                XML_LOCAL_NAME_TMODELKEY);
        categoryBag.add(xmlLocalNameKR);

        Vector services = new Vector();
        services.add(service);
        ServiceDetail serviceDetail = proxy.save_service(authInfo, services);
        return serviceDetail;
    }

The publish_service() method does the following:

  1. Sets the businessService name to the value of the serviceName parameter if the service does not already have a default name. The serviceName parameter is the name of the WSDL service; this should only be used as the name of the UDDI businessService if the businessService does not already have a name.
  2. Creates a categoryBag, if one was not supplied in the service parameter, and adds three keyedReferences to it: one for the WSDL entity type taxonomy, with a value of service; one for the XML namespace taxonomy, using the value of the namespaceName parameter as the namespace name; and one for the XML local name taxonomy, using the value of the serviceName parameter as the local name, regardless of whether or not the businessService name was supplied.

The version of the method to publish a service that takes as parameters only the information required by the Technical Note is shown in Listing 11.


Listing 11. Method to publish a service, without any additional information
public ServiceDetail publish_service(
        String businessKey,
        String namespaceName,
        String serviceName)
        throws UDDIException, TransportException
    {
        BusinessService service = new BusinessService();
        service.setBusinessKey(businessKey);
        service.setServiceKey("");
        BindingTemplates bindingTemplates = new BindingTemplates();
        service.setBindingTemplates(bindingTemplates);
        return publish_service(service, namespaceName, serviceName);
    }

publish_bindingTemplate()

The publish_bindingTemplate() method that takes the extra parameter is shown in Listing 12.


Listing 12. publish_bindingTemplate() method with an extra parameter
public BindingDetail publish_bindingTemplate(
        BindingTemplate bindingTemplate,
        String endpoint,
        String urlType,
        String portName,
        String bindingTModelKey,
        String portTypeTModelKey)
        throws UDDIException, TransportException
    {
        AccessPoint accessPoint = new AccessPoint(endpoint, urlType);
        bindingTemplate.setAccessPoint(accessPoint);
        TModelInstanceDetails tmid = new TModelInstanceDetails();
        InstanceParms ip = new InstanceParms(portName);
        InstanceDetails id = new InstanceDetails();
        id.setInstanceParms(ip);
        TModelInstanceInfo bindingTMII =
            new TModelInstanceInfo(bindingTModelKey);
        bindingTMII.setInstanceDetails(id);
        tmid.add(bindingTMII);
        TModelInstanceInfo portTypeTMII =
            new TModelInstanceInfo(portTypeTModelKey);
        tmid.add(portTypeTMII);
        bindingTemplate.setTModelInstanceDetails(tmid);

        Vector bindingTemplates = new Vector();
        bindingTemplates.add(bindingTemplate);
        BindingDetail bindingDetail =
            proxy.save_binding(authInfo, bindingTemplates);
        return bindingDetail;
    }

The publish_bindingTemplate() method does the following:

  1. Creates an AccessPoint based on the endpoint and urlType parameters and sets it as the accessPoint of the supplied bindingTemplate.
  2. Creates a new instance of tModelInstanceDetails and sets it as the tModelInstanceDetails of the bindingTemplate.
  3. Creates an instance of InstanceDetails and sets the value of the portName parameter as the InstanceParms of the InstanceDetails.
  4. Creates an instance of TModelInstanceInfo using the bindingTModelKey parameter value and sets the instanceDetails property to that created in the previous step. This instance of TModelInstanceInfo is added to the TModelInstanceDetails.
  5. Creates an instance of TModelInstanceInfo using the portTypeTModelKey parameter value and adds it to the TModelInstanceDetails.

The version of the method to publish a bindingTemplate that takes as parameters only the information required by the Technical Note is shown in Listing 13.


Listing 13. Method to publish a bindingTemplate, without any additional information
public BindingDetail publish_bindingTemplate(
        String serviceKey,
        String endpoint,
        String urlType,
        String portName,
        String bindingTModelKey,
        String portTypeTModelKey)
        throws UDDIException, TransportException
    {

Sample

The purpose of the sample application is to show how you can use the Java language to achieve the same effect achieved in Part 3 of the series using the UDDI GUI. The goal is to publish a UDDI model of the WSDL for an implementation of the WS-I sample application. Apart from the keys generated for the tModels and so forth, the UDDI model published should be exactly the same as the one described in Part 3.

Authentication

A full description of the support for authentication in the IBM WebSphere UDDI registry is outside the scope of this article. It should be noted that when WebSphere Global Security is off, no UDDI authentication is required. This is the mode of operation that this sample assumes.

Structure of the sample

Our sample application is written as a Java class with a main() method. The fully-qualified name of the class is uddi.wsdl.v2.publish.PublishSample. The class definition and the main() method are shown in Listing 14.

        "uuid:68DE9E80-AD09-469D-8A37-088422BFBC36";

    public static void main(String[] args)
    {
        UDDIProxy proxy = new UDDIProxy();
        try
        {
            proxy.setPublishURL(args[0]);
            try
            {
                String authInfo = ""; // Assume no security
                Publish publish = new Publish(proxy, authInfo);

                publishBusinesses(proxy, authInfo);
                publishPortTypeTModels(publish);
                publishBindingTModels(publish);
                publishServices(publish);
            }
            catch (TransportException te)
            {
                te.printStackTrace(System.err);
            }
            catch (UDDIException uddie)
            {
                uddie.printStackTrace(System.err);
            }
        }
        catch (MalformedURLException murle)
        {
            System.err.println("publish URL malformed");
        }
    }

The main() method expects a single argument: the publishURL to be used with the UDDI4J proxy. The method constructs the UDDI4J proxy and then constructs an instance of the Publish class using this UDDI4J proxy instance and a fixed authInfo value of "" (as WebSphere Global Security is assumed to be off).

The main method then calls the following private static methods in turn, passing in either the UDDI4J proxy or the Publish instance, as appropriate:

  1. publishBusinesses()
  2. publishPortTypeTModels()
  3. publishBindingTModels()
  4. publishServices()

The following sections consider each of these methods in more detail.

publishBusinesses()

As the WSDL Technical Note does not say anything about the businessEntity elements used to contain WSDL-described services, there are no special considerations for the businesses used for the WS-I sample application. Thus, this method only requires the UDDI4J proxy; it does not require the Publish instance. This method creates the five businesses used in Part 3 of this series and prints out the key of each businessEntity. The code for this method is shown in Listing 15.


Listing 15. Method to publish sample businesses
private static void publishBusinesses(UDDIProxy proxy, String authInfo)
        throws UDDIException, TransportException
    {
        BusinessDetail result = null;
        Vector businessVector = new Vector();
        BusinessEntity configuratorA = new BusinessEntity();
        configuratorA.setBusinessKey("");
        configuratorA.setDefaultNameString("ConfiguratorA", "en-US");
        businessVector.add(configuratorA);
        BusinessEntity loggingFacilityA = new BusinessEntity();
        loggingFacilityA.setBusinessKey("");
        loggingFacilityA.setDefaultNameString("LoggingFacilityA", "en-US");
        businessVector.add(loggingFacilityA);
        BusinessEntity manufacturerA = new BusinessEntity();
        manufacturerA.setBusinessKey("");
        manufacturerA.setDefaultNameString("ManufacturerA", "en-US");
        businessVector.add(manufacturerA);
        BusinessEntity warehouseA = new BusinessEntity();
        warehouseA.setBusinessKey("");
        warehouseA.setDefaultNameString("WarehouseA", "en-US");
        businessVector.add(warehouseA);
        BusinessEntity retailerA = new BusinessEntity();
        retailerA.setBusinessKey("");
        retailerA.setDefaultNameString("RetailerA", "en-US");
        businessVector.add(retailerA);
        result = proxy.save_business(authInfo, businessVector);
        if (!result.getTruncatedBoolean())
        {
            Vector resultVector = result.getBusinessEntityVector();
            if (resultVector.size() == 5)
            {
                configuratorAKey =
                    ((BusinessEntity) (resultVector.elementAt(0)))
                        .getBusinessKey();
                System.out.println("configuratorA key is " + configuratorAKey);

                loggingFacilityAKey =
                    ((BusinessEntity) (resultVector.elementAt(1)))
                        .getBusinessKey();
                System.out.println(
                    "loggingFacilityA key is " + loggingFacilityAKey);

                manufacturerAKey =
                    ((BusinessEntity) (resultVector.elementAt(2)))
                        .getBusinessKey();
                System.out.println("manufacturerA key is " + manufacturerAKey);

                warehouseAKey =
                    ((BusinessEntity) (resultVector.elementAt(3)))
                        .getBusinessKey();
                System.out.println("warehouseA key is " + warehouseAKey);

                retailerAKey =
                    ((BusinessEntity) (resultVector.elementAt(4)))
                        .getBusinessKey();
                System.out.println("retailerA key is " + retailerAKey);
            }
        }
    }

publishPortTypeTModels()

This method creates five portType tModels, one for each of the interfaces in the WS-I sample application. As there is no extra information required for the portType tModels, the version of publish_portType_tModel() that does not take the extra parameter is called; only the appropriate namespace name, portType name, and URL are required. The key of each created tModel is printed out. The code for this method is shown in Listing 16 in this sidefile.

publishBindingTModels()

This method creates five binding tModels, one for each of the portType tModels. As mentioned earlier, because the WS-I conformance information needs to be added to the binding tModels, this example uses the publish_binding_tModel() method that takes an extra parameter. The TModel instance that is passed in contains only a categoryBag with a single keyedReference for the WS-I conformance statement. As the publish_binding_tModel() method updates the tModel instance passed to it, the instance must be recreated before each call to the method. The key of each created tModel is then printed out. The code for this method is shown in Listing 17 in this sidefile.

publishServices()

This method creates the five businessServices, and for each one creates a bindingTemplate. No additional information is required for either the businessServices or the bindingTemplates, so the appropriate methods that do not take the extra parameter are used. The keys of each created businessService and bindingTemplate are printed out. The code for this method is shown in Listing 18.

Conclusion

In this article, you've learned how to use the Java language and UDDI4J to implement the approach to publishing as defined in the Technical Note. You also saw a sample class that publishes the UDDI model for the WS-I Sample Application.

The next article in this series will show you how to write code to issue the queries described in the Technical Note.
