<H2><A name="GettingStartedwithTuscanyRelease1.0-InstalltheTuscanyDistribution%26nbsp%3B"></A>Install the Tuscany Distribution </H2>
<P>The first thing you do is to create a folder on you disk into which you will download the TUSCANY distribution.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/tuscany_folder.png" align="absmiddle" border="0"></P>
<P>Next you download the latest release distribution. Launch your browser and enter one of the<BR>
following URL's.<BR>
Latest Release - <SPAN class="nobr"><A href="http://cwiki.apache.org/TUSCANY/sca-java-releases.html" title="Visit page outside Confluence" rel="nofollow">http://cwiki.apache.org/TUSCANY/sca-java-releases.html<SUP><IMG class="rendericon" src="http://cwiki.apache.org/confluence/images/icons/linkext7.gif" height="7" width="7" align="absmiddle" alt="" border="0"></SUP></A></SPAN><BR>
Download both the <B><EM>bin zip</EM></B> as well as the <B><EM>src zip</EM></B> to the folder that you created on your disk. Once you completed the download you should see the following on your disk.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/release_zips.png" align="absmiddle" border="0"><BR>
<BR>
Next you unzip the <B><EM>bin zip</EM></B> in place, you should see the following folder file structure on your disk after unzip is complete.<BR>
<IMG src="getting-started-with-tuscany-release-10.data/folder_structure.png" align="absmiddle" border="0"></P>
<H2><A name="GettingStartedwithTuscanyRelease1.0-SetupEclipseforTuscany"></A>Setup Eclipse for Tuscany</H2>
<P>Start Eclipse and create a User Library to contain the TUSCANY runtime jar's as well as their<BR>
depending jar's.</P>
<P>From the menu bar select <B><EM>Window</EM></B> and then <B><EM>Preferences...</EM></B> . The Preferences dialog will appear,<BR>
in its left navigation tree select <B><EM>Java</EM></B>, followed by <B><EM>Build Path</EM></B>, and followed by <B><EM>User Libraries</EM></B>.<BR>
Select the <B><EM>New...</EM></B> pushbutton on the right of the New Libraries dialog to create a new user library.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/New_User_Lib.png" align="absmiddle" border="0"></P>
<P>The user library created is empty, select the <B><EM>Add JARs...</EM></B> pushbutton on the right to add all the<BR>
jar's from your Tuscany installation <B><EM>lib folder</EM></B>. When completed all the jar's will appear under the<BR>
TUSCANY user library.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/Tuscany_User_Lib.png" align="absmiddle" border="0"></P>
<P>Since some of you maybe interested in <B><EM>debugging</EM></B> also the Tuscany runtime code we will attach<BR>
the Tuscany source to the Tuscany runtime jar in the following step. In the User Libraies dialog<BR>
scroll down until you see the <B><EM>Tuscany runtime jar</EM></B> and select its <B><EM>Source attachment.</EM></B></P>
<P><IMG src="getting-started-with-tuscany-release-10.data/source_attachment.png" align="absmiddle" border="0"></P>
<P>Select the <B><EM>Edit...</EM></B> pushbutton on the right and in the Edit dialog use the <B><EM>External File...</EM></B> pushbutton<BR>
to the select the Tuscany <B><EM>src zip</EM></B> that we downloaded earlier.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/source_attachment_config.png" align="absmiddle" border="0"></P>
<P>Select <B><EM>OK</EM></B> to complete this and the Preferences dialog, and you are done with the Tuscany setup<BR>
for Eclipse.</P>
<H2><A name="GettingStartedwithTuscanyRelease1.0-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><IMG src="getting-started-with-tuscany-release-10.data/first_composite.png" align="absmiddle" border="0"></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="GettingStartedwithTuscanyRelease1.0-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 <IMG src="getting-started-with-tuscany-release-10.data/new_java_project.png" align="absmiddle" border="0"> 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>
<IMG src="getting-started-with-tuscany-release-10.data/new_java_project_dlg.png" align="absmiddle" border="0"><BR>
<BR>
<IMG src="getting-started-with-tuscany-release-10.data/project_layout.png" align="absmiddle" border="0"><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 TUSCANY user library to the project.<BR>
<BR>
<IMG src="getting-started-with-tuscany-release-10.data/new_java_project_lib.png" align="absmiddle" border="0"><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>
<IMG src="getting-started-with-tuscany-release-10.data/new_java_project_folder.png" align="absmiddle" border="0"><BR>
<BR>
</P>
<H2><A name="GettingStartedwithTuscanyRelease1.0-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 <IMG src="getting-started-with-tuscany-release-10.data/new_java_pkg_btn.png" align="absmiddle" border="0"> 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>
<IMG src="getting-started-with-tuscany-release-10.data/new_java_pkg_dlg.png" align="absmiddle" border="0"><BR>
<BR>
Repeat the previous step to create another package named "ufservices". The store project now<BR>
should look as follows.<BR>
<BR>
<IMG src="getting-started-with-tuscany-release-10.data/new_java_pkg_folder.png" align="absmiddle" border="0"><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="GettingStartedwithTuscanyRelease1.0-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 <IMG src="getting-started-with-tuscany-release-10.data/class_btn.png" align="absmiddle" border="0"> and select the <B><EM>New Java Interface</EM></B> <IMG src="getting-started-with-tuscany-release-10.data/interface_btn.png" align="absmiddle" border="0"> 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"><DIV class="codeContent">
<PRE class="code-java"><SPAN class="code-keyword">package</SPAN> services;
<SPAN class="code-keyword">import</SPAN> org.osoa.sca.annotations.Remotable;
@Remotable
<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 <IMG src="getting-started-with-tuscany-release-10.data/class_btn.png" align="absmiddle" border="0"> . In the dialog enter<BR>

Congratulations you completed your 1st composite service applications, now its time to take it into<BR>
action.</P>
<H2><A name="GettingStartedwithTuscanyRelease1.0-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 "Launch" class in the "launch" package of your "store" 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> <IMG src="getting-started-with-tuscany-release-10.data/eclipse_console.png" align="absmiddle" border="0"></P>
<P> Next Launch your Web browser and enter the following address:</P>
<P><SPAN class="nobr"><A href="http://localhost:8080/ufs/store.html" title="Visit page outside Confluence" rel="nofollow">http://localhost:8080/ufs/store.html<SUP><IMG class="rendericon" src="http://cwiki.apache.org/confluence/images/icons/linkext7.gif" height="7" width="7" align="absmiddle" alt="" border="0"></SUP></A></SPAN> </P>
<P> You get to the Store user facing service of the composite service application.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/store_page.png" align="absmiddle" border="0"></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>
<P> <IMG src="getting-started-with-tuscany-release-10.data/store_page_1.png" align="absmiddle" border="0"></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 <IMG src="getting-started-with-tuscany-release-10.data/atom_feed.png" align="absmiddle" border="0">. You get the browsers default rendering for ATOM feeds.</P>
<P> <IMG src="getting-started-with-tuscany-release-10.data/atom_feeds_page.png" align="absmiddle" border="0"></P>
<P> Use the browser back button to get back to the Store page.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/store_page_2.png" align="absmiddle" border="0"></P>
<P>And then you can Checkout to complete your order.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/store_page_3.png" align="absmiddle" border="0"></P>
<H2><A name="GettingStartedwithTuscanyRelease1.0-ExploretheSamplesfromtheTuscanyDistribution"></A>Explore the Samples from the Tuscany Distribution</H2>
<P>The sample folder of the Tuscany distribution provides a rich set of samples ready for you to explore.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/tuscany_samples_folder.png" align="absmiddle" border="0"><BR>
<BR>
In Eclipse create a New Java Project, specify the project name, select Create project from<BR>
existing source, and specify the folder that contains the sample source.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/New_Calc_Java_Project.png" align="absmiddle" border="0"><BR>
<BR>
Use <B><EM>Next</EM></B> to get to the next page in the New Java Project dialog. There go to the <B><EM>Libraries</EM></B> tab, use<BR>
the <B><EM>Add Library</EM></B>... pushbutton to add the JUnit library and the user library <B><EM>TUSCANY</EM></B>.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/New_Calc_Java_Project_lib.png" align="absmiddle" border="0"><BR>
<BR>
Finish the New Java Project dialog. You now have the sample project available in the Eclipse workbench.</P>
<P><IMG src="getting-started-with-tuscany-release-10.data/calculator_proj_dlg.png" align="absmiddle" border="0"><BR>
<BR>
For the calculator sample that we've chosen go to its <B><EM>CalculatorClient</EM></B> class and select <B><EM>Run As -></EM></B><BR>
<B><EM>Java Application.</EM></B> You will see the following output in the console.</P>
