Calculator Sample
=================
This sample implements a simple a version of the BigBank scenrio used in
various places in the SCA specification documents.
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-simple-bigbank.jar bigbank.client.BigBankClient
and on *nix do
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-simple-bigbank.jar bigbank.client.BigBankClient
Sample Overview
---------------
This sample demonstrates a simple bank summary transaction while using Java components wired together.
SCA default binding is used.
A request to the AccountComponent results in a request to the AccountDataComponent to get account data
which is based on a random stock quote price. Therefore result for this sample will vary on each run.

Building And Running The Sample Using Ant
-----------------------------------------
With the binary distribution the sample can be built and run using Ant as
follows
cd simple-bigbank
ant compile
ant run
You should see the following output from the run target.
** Please note that the balance amount is dependent on the random sotck quote price and the
numbers may vary on each run.
run:
[java] Getting stock quote for: IBM, value: 104.06
[java] Account summary: currency: USD, [ID:Foo_CHA12345, balance:1500.0, ID
:Foo_SAA12345, balance:1500.0, ID:Foo_STA12345, symbol:IBM, quantity:100, balanc
e:10406.0]
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 simple-bigbank
mvn
You should see the following output from the test phase.
** Please note that the balance amount is dependent on the random sotck quote price and the numbers may vary on each run.
