Calculator Script Sample
|
|
========================
|
|
This sample implements a simple calculator using SCA components implemented
|
|
using Java, JavaScript, Ruby, Python and Groovy.
|
|
|
|
The README in the samples directory (the directory above this) provides
|
|
general instructions about building and running samples. Take a look there
|
|
first.
|
|
|
|
If you just want to run it to see what happens open a command prompt, navigate
|
|
to this sample directory and do:
|
|
|
|
ant run
|
|
|
|
OR if you don't have ant, on Windows do
|
|
|
|
java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-script.jar calculator.CalculatorClient
|
|
|
|
and on *nix do
|
|
|
|
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-script.jar calculator.CalculatorClient
|
|
|
|
Sample Overview
|
|
---------------
|
|
The sample provides a single calculator service with a default SCA (java)
|
|
binding. The CalculatorClient exercises this interface by calling add,
|
|
subtract, multiply and divide operations. This results in messages passing
|
|
to the appropriate components in the composite across the local wires. Each
|
|
component is implemented using a different language.

CalculatorService.java - the first component calls +-/* as

|
CalculatorServiceImpl.java
|
|
AddService.java - adds two numbers
|
|
SubtractService.java - subtracts one number from another
|
|
MultiplyService.java - multiplies two numbers
|
|
DivideService.java - divides one number by another
|
|
CalculatorClient.java - starts the SCA Runtime and
|
|
deploys the Calculator.composite.
|
|
It then calls the deployed Calculator

|
Building And Running The Sample Using Ant
|
|
-----------------------------------------
|
|
With the binary distribution the sample can be built and run using Ant as
|
|
follows
|
|
|
|
cd calculator-script
|
|
ant compile
|
|
ant run
|
|
|
|
You should see the following output from the run target.
|
|
|
|
run:
|
|
[java] 3 + 2=5.0
|
|
[java] 3 - 2=1.0
|
|
[java] 3 * 2=6.0
|
|
[java] 3 / 2=1.5
|
|
|
|
Building And Running The Sample Using Maven
|
|
-------------------------------------------
|
|
With either the binary or source distributions the sample can be built and run
|
|
using Maven as follows.
|
|
|
|
cd calculator-script
|
|
mvn
|
|
|
|
You should see the following output from the test phase.
