Tuscany +Hello World Sample

+

Overview

+

The Tuscany helloworld sample shows using the Tuscany SCA +runtime in a J2SE environment  loading a component that +implements the classic introductory hello world example.

+

Location

This +sample is located  in the samples\sca\helloworld directory.

+

Setup

This sample depends on the Tuscany runtime and the sample jar, + + + sample-helloworld-incubating-M1.jar + + +, both of these must be available on the classpath to run the sample. +
    +
+

Running

+ + In the directory samples/sca/helloworld use the JDK 1.5 java command to run the class helloworld.HelloWorldClient + + 
Linux: java -cp ../../../lib/tuscany-runtime-incubating-M1.jar:target/sample-helloworld-incubating-M1.jar helloworld.HelloWorldClient
+ 
Windows: java -cp ../../../lib/tuscany-runtime-incubating-M1.jar;target/sample-helloworld-incubating-M1.jar helloworld.HelloWorldClient
+ +

Results

+

The sample when run should simply display to the standard +output:
Hello World

+

Code Overview

+The source files are physically organized as shown below: +
src
+---main
    +---java
    ¦   +---helloworld
    ¦           HelloWorldClient.java
    ¦           HelloWorldImpl.java
    ¦           HelloWorldService.java
    ¦
    +---resources
            sca.module
+
+ + + + + + + +
sca.moduleDefines the SCA module and component. Defines for the +HelloWorldServiceComponent component  the Java class that +implements that component
HelloWorldService.javaDefines the Java interface implemented by the component.
HelloWorldImpl.javaImplements the SCA component. Uses the SCA service annotation +tag on the class to show what SCA interface is being implemented.
HelloWorldClient.javaCreates a Tuscany runtime and starts it.  Obtains +the module context which was defined by the sca.module file. From the +module context locates the HelloWorldServiceComponent and then +calls  the getGreetings method to invoke the component.
