to create.</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>

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>

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>

<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>

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 "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> <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><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 "admin" 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>
