<P>The first thing you do is to start Eclipse and go to <B>Help -> Software Updates -> Find and Install</B>,<BR>
select "Search for new features to install" 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>"New Remote Site..."</B> to create a new site entry. Give it a name such as<BR>
"Tuscany" 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>"Remote Site"</B> that was just created is selected, and click <B>"Finish"</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>"Apache Tuscany SCA Tools"</B> and click <B>"Next"</B>, and then, on the next dialog, click <B>"Finish"</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><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> in the toolbar to launch the project creation dialog.<BR>
Next you enter "store" 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>
<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>
<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>
<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>
<BR>
<BR>
Hit the <B><EM>Finish</EM></B> button to complete the <B><EM>New Java Project</EM></B> dialog to create the "store" java project. <BR>
<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>
<BR>
</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 "store" 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 "services" 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>
<BR>
Repeat the previous step to create another package named "ufservices". The store project now<BR>
should look as follows.<BR>
<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>
<BR>
In the following you will place in the "services" package the regular services, and in the "ufservices"<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 "services" package. Next you click on the dropdown arrow next to the <B><EM>New Java Class</EM></B><BR>
button <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> and select the <B><EM>New Java Interface</EM></B> <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 "Catalog" 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>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

<SPAN class="code-keyword">public</SPAN> <SPAN class="code-keyword">interface</SPAN> Catalog {
<SPAN class="code-object">String</SPAN>[] get();
}
</PRE>
</DIV></DIV>
<P>Select the "services" package again. Select the <B><EM>New Java Class</EM></B> button <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> . In the dialog enter<BR>
"CatalogImpl" as the <B><EM>Name</EM></B> of the class, add "Catalog" 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>

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>

<P> <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> 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> </P>
<P> You get to the Store user facing service of the composite service application.</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 "admin" for both.</P>
