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.
