+Tuscany - Getting Started - Helloworld Sample

+---------------------------------------------

+

+This sample demonstrates a simple helloworld style SCA application and how to run that with Tuscany.

+

+See the README in the top-level samples folder for general information on the Tuscany samples.

+

+This project creates an SCA contribution with a deployable composite named helloworld.comosite.

+The composite defines an SCA component, HelloworldComponent, which provides a Helloworld service, 

+the component is implemented by a Java class. 

+

+You can use the contribution by starting the composite in the Tuscany Shell. To do that run the 

+following command in the helloworld-contribution folder:

+

+   mvn tuscany:run 

+

+Alternatively, the Tuscany Shell can be started with the scripts in the Tuscany binary distribution 

+bin folder. To do that run the following command at the root of a Tuscany binary distribution:

+

+   bin\tuscany.bat samples\getting-started\helloworld-contribution  

+

+Once the Shell has been started with one of those methods you can use Shell commands to explore

+the SCA domain, for example, use the "installed" command to get the status of installed contributions, 

+"services" to see the available component services, and you may test calling the helloworld service by 

+using the "invoke" command:

+

+   invoke HelloworldComponent sayHello yourName

+

+---

+ 

+This sample was created by the Tuscany contribution-jar Maven archetype. You can use that archetype to 

+create your own SCA contribution projects by running the following Maven command:

+

+   mvn archetype:generate -DarchetypeCatalog=http://tuscany.apache.org

+

+then at the prompt select 1 to choose the contribution-jar archetype and then answer the questions. 

+This project used the following answers:

+

+   Define value for property 'groupId': : org.apache.tuscany.sca.samples

+   Define value for property 'artifactId': : helloworld-contribution

+   Define value for property 'version': 1.0-SNAPSHOT: 2.0-SNAPSHOT

+   Define value for property 'package': org.apache.tuscany.sca.samples: sample
