| <h1>Introduction </h1> |
| <p> The Web Tools Platform (WTP) Project extends Eclipse with a set of open-source |
| Web services development tools and API's. This tutorial gives an overview of |
| the project and focuses on its Web Services support.</p> |
| <p>At present the project is divided into three sub projects:</p> |
| <p> Web Standard Tools (WST)<br> |
| J2EE Standard Tools (JST)<br> |
| Java Server Faces Tools (JSF) </p> |
| <p>The Web Standard Tools subproject contains support for XML Web services, including |
| tools based on standards defined by the W3C, Oasis, WS-I and others. WS-I is |
| an open industry organization chartered to promote Web services interoperability |
| across platforms, operating systems and programming languages. The organizations |
| diverse community of Web services leaders helps customers to develop interoperable |
| Web services by providing guidance, recommended practices and supporting resources.</p> |
| <p>The J2EE Standard Tools subproject contains support for standards defined by |
| the Java Community Process, such as JAX-RPC and JSR-109, and for reference implementations |
| of these standards, such as Apache Axis. The project contains both a set of |
| tools for Web services developers and a set of API's for Web services tool creators.</p> |
| <p>The Java Server Faces Tools project will provide tools and API's for JSR 127 |
| which is part of Java EE 5. The project will operate as an incubator during |
| the WTP 1.0 development cycle and will become a component of the JST subproject |
| in WTP 1.5.</p> |
| <p>Collectively, these three sub projects include tools for HTML, XML, Web Services, |
| J2EE and JSF development along with Server tools for integrating application |
| servers, including Apache Tomcat, Apache Geronimo, JBoss, IBM WebSphere and |
| BEA WebLogic.</p> |
| <p> </p> |
| <p><img src="images/tip.gif" width="62" height="13"> This tutorial uses the Eclipse |
| Web Tools Platform 1.0 and Apache Tomcat 5.5 for it's demonstrations. The locations |
| for downloads are given in the <em><strong>References and Resources </strong></em>section |
| at the end.</p> |
| <p> </p> |
| <p> </p> |
| <h1>Building a 'Stock Quote' Web Service Client Using the Eclipse WTP</h1> |
| <p> Although WTP provides many tools that are useful in Web Application development, |
| this tutorial will focus on the tools that are directly related to Web Services |
| development, testing and deployment. These tools, mostly integrated under the |
| Web Standards Tools sub project, are;</p> |
| <p> 1. Web Service Explorer<br> |
| 2. WSDL/XSD Editor<br> |
| 3. Web Service Wizard and<br> |
| 4. WS-I Test Tools <br> |
| </p> |
| <p>In the following sections of this tutorial, we will look into the usage of |
| these tools in Web Services development. We will consider a scenario where we |
| are entrusted to implement a Web Service client for a 'Stock Quote' service. |
| Using the Eclipse WTP, we will;</p> |
| <ul> |
| <li> Search for an exposed 'Stock Quote' service in a UDDI registry,</li> |
| <li>Access the WSDL for this service,</li> |
| <li>Import the WSDL to the Eclipse WTP workbench,</li> |
| <li>Generate code (stubs) using the WSDL,</li> |
| <li>Test the service and finally</li> |
| <li>Validate WS-I compliance</li> |
| </ul> |
| <p>At each stage of the tutorial, we will look at a demonstration of how the activities |
| described can be done in the Eclipse WTP.</p> |
| <p> </p> |
| <p> </p> |
| <h2>Finding a candidate service using the 'Web Services Explorer'</h2> |
| <p> The Web Services Explorer helps in the <em><strong>Discovery</strong></em>,<em><strong> |
| Testing </strong></em>and<em><strong> Publishing</strong></em> of Web Services. |
| In order to build a client, we need to first find an exposed Web Service, which |
| satisfies our requirements. After finding several candidates from the published |
| UDDI registry information, it is only natural to test the functionality of the |
| methods provided by the services. The 'Web Services Explorer' provided by the |
| Eclipse WTP provides support for each of these actions as outlined below.<br> |
| </p> |
| <p> <strong>1. Discovery</strong></p> |
| <ul> |
| <li> Searching UDDI Registries </li> |
| <blockquote> |
| <p>UDDI is an acronym for Universal Description, Discovery, and Integration. |
| UDDI defines a platform-independent, XML-based registry for businesses worldwide to list |
| themselves on the Internet. UDDI is an open industry initiative (sponsored |
| by OASIS) enabling businesses to publish service listings and discover each |
| other and define how the services or software applications interact over |
| the Internet. A UDDI business registration consists of three components:</p> |
| <p> 1. White Pages - address, contact, and known identifiers;<br> |
| 2. Yellow Pages - industrial categorizations based on standard taxonomies; |
| and<br> |
| 3. Green Pages - technical information about services exposed by the business</p> |
| <p>UDDI is nominally one of the core Web Services standards. It is designed |
| to be interrogated by SOAP messages and to provide access to WSDL documents |
| describing the protocol bindings and message formats required to interact |
| with the web services listed in its directory.</p> |
| </blockquote> |
| <li> Navigating WSIL (Web Services Inspection Language) Documents </li> |
| <blockquote> |
| <p>WS-Inspection is a web service specification for "discovery documents" |
| developed in a joint effort by Microsoft and IBM. WS-Inspection lists groups |
| of web services and their endpoints in an XML format. Currently, other standards |
| are being used for this purpose, such as Microsoft's DISCO. It is expected |
| that WS-Inspection will eventually replace these standards to become the |
| universally accepted discovery standard for web services.</p> |
| </blockquote> |
| <li> Importing WSDL into development project |
| <blockquote> |
| <p>The Web Services Description Language (WSDL) is an XML format published |
| for describing Web services. Version V 1.1 has not been endorsed by the |
| World Wide Web Consortium (W3C), however it has released a draft for version |
| 2.0 on May 11, 2005, that will be a W3C recommendation, and thus endorsed |
| by the W3C.<br> |
| </p> |
| </blockquote> |
| </li> |
| </ul> |
| <p><strong>2. Test</strong><br> |
| Dynamic invocation based on WSDL<br> |
| View SOAP messages<br> |
| </p> |
| <p><strong>3. Publish</strong><br> |
| Publish WSDL into UDDI Registries</p> |
| <p> </p> |
| <p>In the demonstration below we will 'search' a UDDI registry using the Eclipse |
| WTP and filter the results, in order to obtain a viable candidate service for |
| our client. Then we will invoke some 'service operations' to check the actual |
| outputs and finally 'import' the service WSDL to our workbench.</p> |
| <p> </p> |
| <h3>Demonstration</h3> |
| <h4> Launching the Web Services Explorer</h4> |
| <p><img src="images/tryit.gif" width="61" height="13"> Make sure that you are |
| in the <em><strong>J2EE Perspective</strong></em> in Eclipse. In the J2EE perspective, |
| clicking the 'Launch Web Services Explorer' button in the Eclipse WTP tool bar |
| will launch the Web Services Explorer in your default web browser (in this instance, |
| Mozilla Firefox). The default registry queried is the IBM Test UDDI registry. |
| </p> |

| <p>Figure 1 - Eclipse WTP workbench with the ' <em><strong>Launch Web Services |
| Explorer</strong></em>' button highlighted </p> |
| <h4> </h4> |
| <h4>Web Services Explorer Launched In the Eclipse WTP</h4> |
| <p>In this tutorial we will use the 'XMethods' UDDI registry to get ourselves |
| familiar with the Web Services Explorer. </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Select the registry from |
| the drop down list, register for an account, activate the account and we are |
| ready to move forward.<br> |
| Click the 'Go' button to begin exploring the registry.</p> |
| <h4><img src="images/web-service-explorer.jpg" width="1024" height="768"></h4> |
| <p>Figure 2 - The Web Services Explorer<br> |
| </p> |
| <p> </p> |
| <h4>Searching For Exposed Web Services in the UDDI registry<br> |
| </h4> |
| <p>After accessing the registry, we need to find a Web Service to work with. </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Click the 'Find' button |
| and type 'Stock Quote Services' as the <em><strong>name of this query</strong></em>. |
| In the <em><strong>name</strong></em> text box, type 'Stock Quote' (which we |
| know exists). In the combo box you get three selections as <em><strong>Businesses</strong></em>, |
| <em> <strong>Services</strong></em> or <em><strong>Service Interfaces</strong></em>. |
| Select Services there. Click Go to execute the search.</p> |
| <p><img src="images/search-services.jpg" width="1024" height="768"></p> |

| <p>Figure 4 - Search query results displayed</p> |
| <p> </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Click on one of the results |
| to view service information. Then click 'Add To WSDL Page' to add this service |
| to the WSDL page to further explore it.</p> |
| <p><img src="images/service-details-displayed.jpg" width="1024" height="768"></p> |
| <p>Figure 5 - Add to WSDL action selected</p> |
| <h4> </h4> |
| <h4> Invoking Service Operations Available for Developers</h4> |
| <p>We can explore and invoke WSDL operations in the WSDL Page. In this particular |
| service, we can invoke the operation available to get a Stock Quote for a given |
| symbol string. This is good because we can actually try out the service methods |
| and verify whether the expected output is provided by them.</p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Type 'IBM' and check the |
| 'Status' panel for the returned data.</p> |
| <h4><img src="images/invoking-service-operations.JPG" width="1024" height="768"></h4> |
| <p>Figure 6 - Invoking a WSDL operation</p> |
| <p></p> |
| <p> </p> |
| <h4>Importing the Service WSDL to the Workbench</h4> |
| <p> After exploring and finding our services, the next step is to start using |
| them in our Web Applications. In order to do this, we need to create Client |
| stubs along with <em>Web Service Emulators</em> (to test our clients). Using |
| the Eclipse WTP we can import the WSDL of the Web Service explored into the |
| workbench. </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Let's try this using the |
| steps below.<br> |
| </p> |
| <blockquote> |
| <p> 1. Create a simple project in your Eclipse WTP workbench (Ex: WTPtutorial)<br> |
| 2. Click 'Import WSDL To Workbench' button in the web services explorer, as |
| illustrated below<br> |
| 3. Select the appropriate project to import the WSDL to (in this instance, |
| WTPtutorial)<br> |
| 4. Give a name to the generated WSDL file in the project.</p> |

| <p>Figure 7 - Importing the WSDL of the service to the workbench</p> |
| <p></p> |
| <h2> </h2> |
| <h2>Editing Documents with the WSDL/XSD Editor</h2> |
| <p>As described previously, The Web Services Description Language (WSDL) is the |
| XML format published for describing Web services. WSDL describes the public |
| interface to the web service. This is an XML-based service description on how |
| to communicate using the web service; namely, the protocol bindings and message |
| formats required to interact with the web services listed in its directory. |
| The supported operations and messages are described abstractly, and then bound |
| to a concrete network protocol and message format.</p> |
| <p>WSDL is often used in combination with SOAP and XML Schema to provide web services |
| over the internet. A client program connecting to a web service can read the |
| WSDL to determine what functions are available on the server. Any special data |
| types used are embedded in the WSDL file in the form of XML Schema. The client |
| can then use SOAP to actually call one of the functions listed in the WSDL.</p> |
| <p>An XML Schema Definition (XSD) is an instance of an XML schema written in the |
| W3C's XML Schema language. An XSD defines a type of XML document in terms of |
| constraints upon what elements and attributes may appear, their relationship |
| to each other, what types of data may be in them, and other things.<br> |
| </p> |
| <p> The WSDL/XSD Editor provided by the Eclipse WTP provides the developer with |
| functionality expected from an advanced editor such as;<br> |
| </p> |
| <p> Graphical and Source editing modes<br> |
| Seamless integration for editing inline XSD<br> |
| Content Assist<br> |
| Pop-up actions<br> |
| Binding Wizard<br> |
| Validation, including WS-I profiles<br> |
| Extensible for WSDL extension elements</p> |
| <p>Illustrated below is the WSDL imported from the above section. It is displayed |
| in the WSDL editor running in <em><strong>graphical</strong></em> mode.</p> |
| <h3><img src="images/wsdl-editor-graphical-mode.JPG" width="1024" height="768"></h3> |
| <p>Figure 8 - The WSDL editor running in graphical mode</p> |

| <h3> </h3> |
| <h3>WSDL Editor Demonstration</h3> |
| <p><br> |
| <img src="images/tryit.gif" width="61" height="13"> We will try the editor following |
| the steps below.</p> |
| <blockquote> |
| <p><br> |
| 1. Open StockQuote.wsdl in WSDL Editor<br> |
| 2. Go into graphical view of XML schema for messages<br> |
| 3. Navigate into GetQuote element<br> |
| 4. Switch to Source tab<br> |
| 5. Navigate using linked Outline and Properties views</p> |
| </blockquote> |
| <p>In the illustration below, we can see the editor in 'Source' mode along with |
| the Eclipse workbench content outline.</p> |

| <h2> </h2> |
| <h2>Generating Code Using the Web Services Wizard</h2> |
| <p> The next stage in the tutorial is to start creating and accessing web services. |
| The Eclipse WTP Web Services Wizard provides the tools for doing just that. |
| </p> |
| <p>The wizard;<br> |
| </p> |
| <p> 1. Supports generate/deploy/test/publish lifecycle<br> |
| 2. Configures project, server, and SOAP engine<br> |
| 3. Has highly extensible |
| <ul> |
| <li> SOAP engines</li> |
| <li> Code generators</li> |
| <li> Test facilities </li> |
| </ul></p> |
| <p> </p><h3>Web Services Client Wizard Demonstration</h3> |
| <p> In this demonstration, we will create a Web Service client for our 'Stock |
| Quote' service. We will follow the Generate, Deploy, Test and Publish life cycle. |
| </p> |
| <h4><br> |
| 1. Configuring the Server</h4> |
| <p> First we must configure our server in the Eclipse WTP workbench. This demonstration |
| will use the Apache Tomcat server. </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Go to the Menu File -> |
| New -> Other and Select Servers. Fill your server information as illustrated |
| in the Add New Server wizard.</p> |

| <h4><br> |
| 2. Complete the Web Services Wizard</h4> |
| <p> <img src="images/tryit.gif" width="61" height="13"> The steps are illustrated |
| in the following screen shots. They can be briefly outlined as;</p> |
| <p>1. Run Web Service Client Wizard to generate Java proxy and JSP test page with |
| TCP/IP monitor<br> |
| Go to Menu File -> New -> Other. Expand '<em><strong>Web Services</strong></em>'. |
| Select '<strong><em>Web Service Client</em></strong>'. Click 'Next'.</p> |

| <h4>3. Test the Generated Client Stubs</h4> |
| <p><img src="images/tryit.gif" width="61" height="13"> Here we are setting the |
| end point of the web service (using setEndPoint() method) as http://localhost:9913/stockquote.asmx |
| instead of http://www.webservicex.com/stockquote.asmx. We do this in order |
| to monitor our SOAP requests using TCP/IP monitor.</p> |
| <p><img src="images/test-generated-stubs-1.JPG" width="1024" height="768"></p> |
| <p>Figure 20 - Testing using the generated JSP's hosted in the Tomcat server</p> |
| <p> </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Now go to the Menu Window |
| -> Show View -> Other. Expand Debug and select TCP/IP monitor. This will |
| launch the TCP/IP monitor GUI. Right click as illustrated and select Properties.</p> |
| <p><img src="images/test-generated-stubs-2.JPG" width="1024" height="768"></p> |
| <p>Figure 21 - The TCP/IP monitor GUI</p> |
| <p> </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> In the Properties dialog |
| click Add. In the next dialog, enter 9913 as monitoring port and the real |
| end points details as illustrated below. Click OK and Start to begin monitoring.</p> |
| <p>What happens here is that, all requests going to the real endpoint will be |
| monitored by the TCP/IP monitor. Hence, we get the opportunity to intercept |
| and view all SOAP messages and debug if required.</p> |

| <p>Now that we have all this set up, lets fire a test and see everything in action. |
| </p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Right click the project |
| in the workbench. Click Run As -> Run on Server. The test JSP page will come |
| up. Set the end point as described above. Make sure the TCP/IP monitor is configured |
| and running as illustrated above.</p> |
| <p><img src="images/tryit.gif" width="61" height="13"> Click on the getStockQuote() |
| method. Input a symbol (ex: ibm). If all is well you should get data similar |

| <h2>Maintaining Interoperability Using the WS-I Compliance Tools</h2> |
| <h2> </h2> |
| <h2>What is WS-I?<br> |
| </h2> |
| <p>The Web Services Interoperability Organization is an open industry effort chartered |
| to promote Web Services interoperability across platforms, applications and |
| programming languages. It acts an a standards integrator to help Web services |
| advance in a structured, coherent manner. The WS-I consists of approximately |
| 130 member organizations of which 70% are vendors and 30% are end-user organizations. |
| It has a strong non-U.S. membership, including the very influential Japan SIG.<br> |
| </p> |
| <h2>WS-I Goals</h2> |
| <p>1. Achieve Web services interoperability by integrating specifications, promoting |
| consistent implementations and providing a visible representation of conformance.<br> |
| 2. Accelerate Web services deployment by offering implementation guidance and |
| best practices, delivering tools and sample applications and providing a implementers |
| forum where developers can collaborate.<br> |
| 3. Encourage Web services adoption by building industry consensus to reduce |
| early adopter risks, providing a forum for end users to communicate requirements |
| and raising awareness of customer business requirements</p> |
| <p> </p> |
| <p>The WS-I Compliance tools in Eclipse WTP helps the developer to verify interoperability |
| of the web services developed. These tools are developed in the Eclipse Web |
| Service Validation Tools (WSVT) Project and supports;</p> |
| <p> WS-I Basic Profile 1.0/1.1<br> |
| Simple SOAP Binding Profile 1.0 and <br> |
| Attachments Profile 1.0</p> |
| <p>The Eclipse WTP provides us with;</p> |
| <p> 1. A WSDL 1.1 Validator and<br> |
| 2. A SOAP 1.1 Message Monitor/Analyzer</p> |

| <h1>Conclusion </h1> |
| <p> This tutorial illustrates a common life cycle of a Web Services application |
| in order to highlight the support provided in its development from the Eclipse |
| Web Tools platform. This tutorial is in no way complete, since it would require |
| a book to highlight all the features offered by the Eclipse WTP for Web Services |
| and Web Application developers. Further information on the features of the Eclipse |
| WTP can be found in the Eclipse WTP forums and mailing lists.</p> |
