Build your first Web Services with Tuscany
"Creating Your First Web Service with Apache Tuscany video"
This guide will give you step by step instructions on how to build your first web services.
The first part, we will learn how we can add the Tuscany Runtime to Eclipse IDE.
The second part, will show how easy is to create a webservices using Apache Tuscany.

Create your Service Business Logic
...
In this step you create a Java Project in Eclipse to hold the composite service application.
Click on the New Java Project button 
in the toolbar to launch the project creation dialog.
Next you enter "ws" as the Project name, and for Project Layout select Create separate
folders for sources and class files.
Hit the Next button, and on the following page go to the Libraries tab. Use the Add Library...
button on the right to add the Tuscany Library library to the project.
Hit the Finish button to complete the New Java Project dialog to create the "storews" java project.
Construct Services
...
Next you enter "helloworld" as the package Name, and press the Finish button to complete the
dialog.
HelloWorld
In this step you create the HelloWorld service interface and implementation.
Select the "helloworld" package. Next you click on the dropdown arrow next to the New Java Class
button 
and select the New Java Interface 
option from the dropdown list. In the dialog
enter "HelloWorld" as the Name of the interface and select the Finish button to complete the dialog.
The Java editor will open on the new created Java interface. Replace the content of the editor by
copy-paste of the following Java interface code snippet.
...
After completing these steps the content of the "ws" project will look as follows.
Note: CatalogImpl is red x'ed because it makes use of the CurrencyConverter interface that we
have not implemented yet.
Compose Services
Now that you have all the required service implementations you compose them together to provide
the store helloworld composite service. The composition is stored in a .composite file.
...
| Code Block |

<?xml version="1.0" encoding="UTF-8"?> <composite xmlns="http://www.osoa.org/xmlns/sca/1.0" xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0" xmlns:c="http://helloworld" targetNamespace="http://helloworld" name="helloworld"> <component name="HelloWorldComponent"> <implementation.java class="helloworld.HelloWorldImpl"/> <service name="HelloWorld"> <binding.ws uri="http://localhost:8080/HelloWorld"/> </service> </component> </composite> |
After completing these steps the content of the "storews" project will look as follows.
Congratulations you completed your 1st composite service applications, now its time to take it into
action.
...
The Eclipse console will show the following messages.
Next Launch your Web browser and enter the following address:
