| <h1 class="topictitle1">Publishing Web services and business entities</h1> |
| <div><p>Through UDDI and WSIL, other applications can discover WSDL documents |
| and bind with them to execute transactions or perform other business processes. </p> |
| <div class="section"><p>UDDI enables the discovery of Web services by providing a distributed |
| registry of businesses and their service descriptions, implemented in a common |
| XML format. In order for a service requestor to discover a service, |
| a service provider must first publish a business entity and at least one business |
| service, and service interface in a UDDI registry. The Web Services |
| Explorer is a Web application that supports the publication, discovery, and |
| maintenance of business entities, business services, and service interfaces.</p> |
| <p>WSIL |
| enables the discovery of Web services by defining a distributed service discovery |
| method that supplies references to service descriptions at the service provider's |
| point-of-offering, by specifying how to inspect a Web site for available Web |
| services. The WSIL specification defines the locations on a Web site |
| where you can look for Web service descriptions. Since WSIL focuses on |
| distributed service discovery, the WSIL specification complements UDDI by |
| facilitating the discovery of services that are available on Web sites |
| that may not be listed yet in a UDDI registry. The Web Services Explorer allows |
| you to generate and explore WSIL documents.</p> |
| <p>The favorites page of the |
| Web Services Explorer allows you to store the location of UDDI registries, |
| business entities, Web services, service interfaces, as well as WSIL and WSDL |
| documents.</p> |
| <p>Use the Web Services Explorer to do any of the following |
| tasks:</p> |
| <ul><li> <a href="taddreg.html">Add a registry to the Web Services Explorer</a> </li> |
| <li> <a href="tbkmrk.html">Adding a registry, business entity, business |
| service, service interface, WSIL, or WSDL service to Favorites</a> </li> |
| <li> <a href="tdiscov.html">Discover a Web service</a> </li> |
| <li> <a href="tpubent.html">Publish a business entity to a registry</a> </li> |
| <li> <a href="tpublish.html">Publish a business service to a registry</a> </li> |
| <li> <a href="tunpub.html">Remove a business entity, business service, |
| or service interface from a registry</a> </li> |
| <li> <a href="tupdate.html">Update a business entity, business service, |
| or service interface</a> </li> |
| <li> <a href="tbusproj.html">Manage referenced services</a> </li> |
| <li> <a href="tassert.html">Manage publisher assertions</a> </li> |
| </ul> |
| <p>Prerequisites:</p> |
| </div> |
| <ol><li class="stepexpand"><span>Before you can use the Web Services Explorer to perform any of |
| these functions, you must <a href="treg.html">register with a public registry</a>. There are many different |
| registries with which you can register.</span> </li> |
| <li class="stepexpand"><span>Ensure that you are using a supported Web browser.</span> The |
| following Web browsers and versions are supported:<ul><li>Internet Explorer: 6.0 and up</li> |
| <li>Mozilla: 1.2.1 and up</li> |
| </ul> |
| </li> |
| <li class="stepexpand"><span> <a href="tstrtexp.html">Launch the Web Services Explorer</a>.</span></li> |
| </ol> |
| <div class="section"><div class="p"><strong>Known limitations of the Web Services Explorer:</strong><ul><li>The taxonomy categories in the Web Services Explorer are not translated |
| since they must match those in the standards adhered to by UDDI (ISO, UNSPSC |
| 7.3, NAICS).</li> |
| <li>The Web Services Explorer will launch without the browser toolbar which |
| shows, amongst other things, the URL to the Web application. This URL should |
| only be used by users with accessibility needs. The URL to the Web Services |
| Explorer Web application can be obtained through the following steps:<ol><li>From the Window menu, select Preferences.</li> |
| <li>In the Preferences dialog, select <span class="uicontrol">Web Browser</span> in |
| the left pane.</li> |
| <li>On the right, select <span class="uicontrol">Use external Web Browser</span>.</li> |
| <li>In the <span class="uicontrol">Location: text</span> field, browse or type in |
| the full path of the Internet Explorer executable. (for example, C:\Program |
| Files\Internet Explorer\iexplore.exe).</li> |
| <li>Click <span class="uicontrol">Apply</span> followed by <span class="uicontrol">OK</span>.</li> |
| </ol> |
| Note that this preference will now apply to any browser windows that |
| are launched by the user or by the tools themselves (such as the Universal |
| Test Client). The Web Services Explorer will now launch in an external browser |
| and its URL should be in the Address field. This can then be pasted or opened |
| using am accessibility assisting browser such as IBM<sup>®</sup> Home Page Reader.</li> |
| <li>When performing an advanced find or publish in the UDDI page of the Web |
| Services Explorer, the items in the drop down list for picking a language |
| in conjunction with a name or description is sorted according to the operating |
| system's locale settings. On Windows<sup>®</sup>, this order may be managed through |
| the Control Panel. To do this:<ol><li>Open the Control Panel.</li> |
| <li>Launch the Regional Options control panel applet.</li> |
| <li>In the General tab of the resulting dialog, there may be a "Sorting order" |
| drop-down list. If so, pick a sorting order and then click <span class="uicontrol">Apply</span> followed |
| by <span class="uicontrol">OK</span>.</li> |
| <li>In the Web Services Explorer, the new sorting order comes into effect |
| once the page reloads. This can be accomplished by pressing the back arrow |
| followed by the forward arrow in the main toolbar.</li> |
| </ol> |
| Note: The instructions above apply to Windows 2000. On Windows XP, |
| the tab mentioned in step 3 is called "Regional Options". Beside the language |
| drop-down, there is a <span class="uicontrol">Customize</span> button. When this is |
| clicked, a new dialog appears. A sorting tab will allow users to pick the |
| sorting method if applicable.</li> |
| </ul> |

| <li class="ulchildlink"><strong><a href="../tasks/tstrtexp.html">Launching the Web Services Explorer</a></strong><br /> |
| The Web services tools allows you to launch the Web Services Explorer |
| in several ways.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/treg.html">Registering with a UDDI registry</a></strong><br /> |
| In order to publish your business entity and Web service to a UDDI |
| registry, you must first register with the registry that you want to use.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/taddreg.html">Adding a Registry to the IBM Web Services Explorer</a></strong><br /> |
| Although the Web Services Explorer comes populated with several |
| registries, you can also add additional registries to your list of favorites.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tpubent.html">Publishing a business entity</a></strong><br /> |
| A business entity contains information about the business that |
| has published a service. Before you can publish a business service, |
| you must publish a business entity.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tpublish.html">Publishing a Web service</a></strong><br /> |
| The Web service, also known as the business service, describes |
| a Web service's endpoint and where its WSDL file resides. The WSDL file lists |
| the operations that service provides.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tupdate.html">Updating a business entity, Web service, or service interface</a></strong><br /> |
| After you have published a business entity, Web service, or service |
| interface, you can update it through the Web Services Explorer.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tunpub.html">Removing a business entity, Web service, or service interface from a registry</a></strong><br /> |
| After you have published a business entity, Web service, or service |
| interface, you can remove or unpublish it through the Web Services Explorer.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tbusproj.html">Managing referenced services</a></strong><br /> |
| A service projection enables a business entity to reference a service |
| that was published by another business entity. By using the businessService |
| structure as a projection to an already published businessService, businesses |
| can share or reuse services. Service projections are managed centrally |
| as part of the referencing businessEntity.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tassert.html">Managing publisher assertions</a></strong><br /> |
| A publisher assertion is a way in UDDI to associate businessEntity |
| structures. The publisher assertion defines a group of businessEntity |
| structures. Many businesses are not effectively represented by a single businessEntity. |
| A publisher assertion allows for associations to be formed between several |
| businessEntity structures. For example, a large company may have several subsidiaries |
| that have different descriptions but are still closely coupled and want to |
| make their relationships visible in UDDI registries.</li> |
| <li class="ulchildlink"><strong><a href="../tasks/tbkmrk.html">Adding a registry, business entity, business service, service interface, WSIL, or WSDL service to Favorites</a></strong><br /> |
| </li> |
| <li class="ulchildlink"><strong><a href="../tasks/tgenwsil.html">Generating a WSIL file</a></strong><br /> |
| Web Services Inspection Language (WSIL) is a service discovery |
| mechanism that is an alternative to UDDI as well as complementary to UDDI. |
| WSIL can be generated at any point in the Web service development cycle once |
| the WSDL file for the Web service has been created.</li> |
