<H2><A name="GettingStartedwithTuscany%28usingTuscanyEclipsePlugin1.1%29-InstalltheTuscanyEclipsePlugin%26nbsp%3B"></A>Install the Tuscany Eclipse Plugin&nbsp;</H2>

<P>The first thing you do is to start Eclipse and go to <B>Help &#45;&gt; Software Updates &#45;&gt; Find and Install</B>,<BR>
select &quot;Search for new features to install&quot; and then click next</P>

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update.jpg" style="border: 0px solid black"></SPAN></P>

<P>On the next dialog, click on <B>&quot;New Remote Site...&quot;</B> to create a new site entry. Give it a name such as<BR>
&quot;Tuscany&quot; and add the site URL as *<A href="http://people.apache.org/~jsdelfino/tuscany/tools/updatesite/*" class="external-link" rel="nofollow">http://people.apache.org/~jsdelfino/tuscany/tools/updatesite/*</A></P>

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update_new_site.jpg" style="border: 0px solid black"></SPAN></P>

<P>Make sure the <B>&quot;Remote&nbsp; Site&quot;</B> that was just created is selected, and click <B>&quot;Finish&quot;</B></P>

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update_finish.jpg" style="border: 0px solid black"></SPAN></P>

<P>Select the <B>&quot;Apache Tuscany SCA Tools&quot;</B> and click <B>&quot;Next&quot;</B>, and then, on the next dialog, click <B>&quot;Finish&quot;</B></P>

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update_search_results.jpg" style="border: 0px solid black"></SPAN></P>

<P>Accept the <B>&quot;Plugin License&quot;</B></P>

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update_feature_license.jpg" style="border: 0px solid black"></SPAN></P>

<P>and next click on <B>&quot;Install All&quot;</B></P>

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update_feature_verification.jpg" style="border: 0px solid black"></SPAN></P>

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

<P><SPAN class="image-wrap" style=""><IMG src="tools-install-tuscany-eclipse-plugins-11.data/install_update_restart_eclipse.jpg" style="border: 0px solid black"></SPAN></P>

<H2><A name="GettingStartedwithTuscany%28usingTuscanyEclipsePlugin1.1%29-Createyour1stCompositeServiceApplication"></A>Create your 1st Composite Service Application</H2>

<P>The following shows the composition diagram for the composite service application you are about<BR>
to create.</P>

<P><SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/first_composite.png" style="border: 0px solid black"></SPAN></P>

<P>The composite service application you will create is a composition of four services. The composed<BR>
service provided is that of an on-line store.<BR>
There is a Catalog service which you can ask for catalog items, and depending on its currency<BR>
code property configuration it will provide the item prices in USD or EUR. The Catalog service is not<BR>
doing the currency conversion itself it references a CurrencyConverter service to do that task. Then<BR>
there is the ShoppingCart service into which items chosen from the catalog can be added, it is<BR>
implemented as a REST service. The Catalog is bound using the JSONRPC binding, and the<BR>
ShoppingCart service is bound using the ATOM binding. Finally there is the Store user facing<BR>
service that provides the browser based user interface of the store. The Store service makes use of<BR>
the Catalog and ShoppingCart service using the JSONRPC, and ATOM binding respectively.</P>

<H2><A name="GettingStartedwithTuscany%28usingTuscanyEclipsePlugin1.1%29-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="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.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;store&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>
<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/new_java_project_dlg.png" style="border: 0px solid black"></SPAN><BR>
&nbsp;<BR>
<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/project_layout.png" style="border: 0px solid black"></SPAN><BR>
&nbsp;<BR>
Hit the <B><EM>Next</EM></B> button, and on the following page go to the <B><EM>Libraries</EM></B> tab. Use the <B><EM>Add Library...</EM></B><BR>
button on the right to add the <B>Tuscany Library</B> library to the project.<BR>
&nbsp;<BR>
<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/new_java_project_lib.png" style="border: 0px solid black"></SPAN><BR>
&nbsp;<BR>
&nbsp;<BR>
Hit the <B><EM>Finish</EM></B> button to complete the <B><EM>New Java Project</EM></B> dialog to create the &quot;store&quot; java project.&nbsp;<BR>
&nbsp;<BR>
<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/new_java_project_folder.png" style="border: 0px solid black"></SPAN><BR>
&nbsp;<BR>
&nbsp;</P>

<H2><A name="GettingStartedwithTuscany%28usingTuscanyEclipsePlugin1.1%29-ConstructServices"></A>Construct Services</H2>

<P>First you create two package folders into which later in this step you place service implementations.<BR>
Select the &quot;store&quot; project and click on the <B><EM>New Java Package</EM></B> button <SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/new_java_pkg_btn.png" style="border: 0px solid black"></SPAN> in the toolbar to launch<BR>
the package creation dialog.</P>

<P>Next you enter &quot;services&quot; as the package <B><EM>Name</EM></B>, and press the <B><EM>Finish</EM></B> button to complete the<BR>
dialog.<BR>
<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/new_java_pkg_dlg.png" style="border: 0px solid black"></SPAN><BR>
&nbsp;<BR>
Repeat the previous step to create another package named &quot;ufservices&quot;. The store project now<BR>
should look as follows.<BR>
&nbsp;<BR>
<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/new_java_pkg_folder.png" style="border: 0px solid black"></SPAN><BR>
&nbsp;<BR>
In the following you will place in the &quot;services&quot; package the regular services, and in the &quot;ufservices&quot;<BR>
package the user facing services of the composite service application you create.</P>

<H3><A name="GettingStartedwithTuscany%28usingTuscanyEclipsePlugin1.1%29-Catalog"></A><EM>Catalog</EM></H3>

<P>In this step you create the Catalog service interface and implementation.<BR>
Select the &quot;services&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="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.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="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/interface_btn.png" style="border: 0px solid black"></SPAN> option from the dropdown list. In the dialog<BR>
enter &quot;Catalog&quot; as the <B><EM>Name</EM></B> of the interface and select the Finish button to complete the dialog.<BR>
The Java editor will open on the new created Java interface. Replace the content of the editor by<BR>
<B><EM>copy-paste</EM></B> of the following Java interface code snippet.</P>

<P><SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/store_project_5.jpg" style="border: 0px solid black"></SPAN><BR>
Congratulations you completed your 1st composite service applications, now its time to take it into<BR>
action.</P>

<H2><A name="GettingStartedwithTuscany%28usingTuscanyEclipsePlugin1.1%29-UseServices"></A>Use Services</H2>

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

<P>First select the &quot;Launch&quot; class in the &quot;launch&quot; package of your &quot;store&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>Java application</EM></B>. The Tuscany runtime will start up adding<BR>
the store composition to its domain.</P>

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

<P>&nbsp;<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/eclipse_console.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/store/store.html" class="external-link" rel="nofollow">http://localhost:8080/store/store.html</A>&nbsp;</P>

<P>&nbsp;You get to the Store user facing service of the composite service application.</P>

<P><SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/store_page.png" style="border: 0px solid black"></SPAN></P>

<P>You can select items from the Catalog and add them to your Shopping Cart.</P>

<P><B>Note:</B> When adding items for the first time you will be asked for <B><EM>userid and password</EM></B> by the<BR>
browser. Enter &quot;admin&quot; for both.</P>

<P> <SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/store_page_1.png" style="border: 0px solid black"></SPAN></P>

<P>Since the ShoppingCart service is bound using the ATOM binding, you can also look at the<BR>
shopping card content in ATOM feed form by clicking on the feed icon <SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/atom_feed.png" style="border: 0px solid black"></SPAN>. You get the browsers default rendering for ATOM feeds.</P>

<P>&nbsp;<SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/atom_feeds_page.png" style="border: 0px solid black"></SPAN></P>

<P>&nbsp;Use the browser back button to get back to the Store page.</P>

<P><SPAN class="image-wrap" style=""><IMG src="getting-started-with-tuscany-using-tuscany-eclipse-plugin-11.data/store_page_2.png" style="border: 0px solid black"></SPAN></P>

<P>And then you can Checkout to complete your order.</P>
