<P>A quick Step by Step walk through of downloading, installing, and verifying the Tuscany Eclipse Plugins.</P>

<P>This section shows you how to install the lastest Tuscany Eclipse plugin. The plugin gives you the ability to run an SCA composite file from the Package Explorer. You will see a &quot;Run As Tuscany&quot; menu item when you bring up the context menu on composite files.</P>

<P>Start Eclipse and go to Help -&gt; Software Updates -&gt; Find and Install. Select &quot;Search for new features to install&quot; and then click next</P>

<P>Create a new Remote Site. On the next dialog, click on &quot;New Remote Site...&quot; to create a new site entry. Give it a name such as<BR>
&quot;Tuscany&quot; and add the site URL from the latest <B><A href="sca-java-1x-releases.html" title="SCA Java 1.x Releases">Tuscany release</A></B> (e.g  <B><A href="http://www.apache.org/dist/tuscany/java/sca/1.5.1/tuscany-sca-1.5.1-updatesite/" class="external-link" rel="nofollow">http://www.apache.org/dist/tuscany/java/sca/1.5.1/tuscany-sca-1.5.1-updatesite/</A></B>.</P>

<P>Select the &quot;Remote Site&quot; you just created, and click &quot;Finish&quot;</P>

<P>Select the &quot;Apache Tuscany SCA Tools&quot; and click &quot;Next&quot;, and then, on the next dialog, click &quot;Finish&quot;. Accept the &quot;Plugin License&quot; and next click on &quot;Install All&quot;.</P>

<P>When asked to &quot;restart eclipse&quot;, click the &quot;yes&quot; button. </P>

<H2><A name="BuildyourfirstWebServiceswithTuscany-CreateyourServiceBusinessLogic"></A>Create your Service Business Logic</H2>

<H2><A name="BuildyourfirstWebServiceswithTuscany-CreateaJavaProject"></A>Create a Java Project</H2>

<P>In this step you create a Java Project in Eclipse to hold the composite service application.<BR>
Click on the <B><EM>New Java Project</EM></B> button <SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/new_java_project.png" style="border: 0px solid black"></SPAN>&nbsp; in the toolbar to launch the project creation dialog.<BR>
Next you enter &quot;ws&quot; as the <B><EM>Project name</EM></B>, and for <B><EM>Project Layout</EM></B> select <B><EM>Create separate</EM></B><BR>
<B><EM>folders for sources and class files.</EM></B><BR>

&nbsp;<BR>
&nbsp;</P>

<H2><A name="BuildyourfirstWebServiceswithTuscany-ConstructServices"></A>Construct Services</H2>

<P>First you create the &quot;helloworld&quot; package folders into which later in this step you place service implementations.<BR>
Select the &quot;ws&quot; project and click on the <B><EM>New Java Package</EM></B> button <SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/new_java_pkg_btn.png" style="border: 0px solid black"></SPAN> in the toolbar to launch<BR>

<SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/ws_new_java_package.JPG" style="border: 0px solid black"></SPAN><BR>
&nbsp;</P>

<H3><A name="BuildyourfirstWebServiceswithTuscany-HelloWorld"></A><EM>HelloWorld</EM></H3>

<P>In this step you create the HelloWorld service interface and implementation.<BR>
Select the &quot;helloworld&quot; package. Next you click on the dropdown arrow next to the <B><EM>New Java Class</EM></B><BR>
button&nbsp; <SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/class_btn.png" style="border: 0px solid black"></SPAN>&nbsp; and select the <B><EM>New Java Interface</EM></B>&nbsp;&nbsp;&nbsp;<SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/interface_btn.png" style="border: 0px solid black"></SPAN> option from the dropdown list. In the dialog<BR>

&quot;HelloWorldImpl&quot; as the <B><EM>Name</EM></B> of the class, add &quot;Catalog&quot; as the interface this class implements, and<BR>
then select <B><EM>Finish</EM></B> to complete the dialog.</P>

<P>The Java editor will open on the new created Java class. Replace the content of the editor by<BR>
<B><EM>copy-paste</EM></B> of the following Java class code snippet.</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

</SPAN>		&lt;/service&gt;
	&lt;/component&gt;
&lt;/composite&gt;
</PRE>
</DIV></DIV>
<P>After completing these steps the content of the &quot;ws&quot; project will look as follows.</P>

<P><SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/ws_new_java_project_structure_3.JPG" style="border: 0px solid black"></SPAN><BR>

<P>Congratulations you completed your 1st composite service applications, now its time to take it into<BR>
action.</P>

<H2><A name="BuildyourfirstWebServiceswithTuscany-UseServices"></A>Use Services</H2>

<P>In this step you launch and use the ws composite service application you created.</P>

<P>First select the &quot;helloworld.composite&quot; file, in your &quot;ws&quot; project. <B><EM>Right click</EM></B> to get the<BR>
context menu, select <B><EM>Run As</EM></B>, and then <B><EM>Tuscany</EM></B>. The Tuscany runtime will start up adding<BR>
the helloworld composition to its domain and will make the helloworld web service live.</P>

<P>The Eclipse console will show the following messages.</P>

<P>&nbsp;<SPAN class="image-wrap" style=""><IMG src="build-your-first-web-services-with-tuscany.data/ws_new_project_console_output.PNG" style="border: 0px solid black"></SPAN></P>

<P>&nbsp;Next Launch your Web browser and enter the following address:</P>

<P><A href="http://localhost:8080/HelloWorld?wsdl" class="external-link" rel="nofollow">http://localhost:8080/HelloWorld?wsdl</A>&nbsp;</P>

<P>You should now have your web service live, and the url should give you back a generated wsdl for the service.</P>
