+Domain Management Sample Tasks
+==============================
+This sample shows how to use a subset of Tuscany to read contribution metadata,
+analyze and resolve contribution dependencies given a set of available contributions.
+
+The README in the samples directory (the directory above this) provides
+general instructions about building and running samples. Take a look there first.
+
+Sample Overview
+---------------
+
+This sample demonstrates how to use some of the APIs for processing the contributions.
+These APIs are currently used under the cover in the domain manager.

+
+Building the Sample Using Maven
+-------------------------------------------
+
+cd domain-management
+mvn
+
+** Please note that the mvn command will just build the sample and will install the required jar files into the Maven repository.
+** In order to run the sample, please see the instructions - "Running the Sample"
+
+Running the Sample
+------------------
+
+** Please make sure that sample is built using above build command(s).
+
+This sample implements following sample domain management tasks:
+
+1. List deployables in a contribution:
+ ------------------------------------
+
+ - This sample reads the SCA metadata for two sample contributions and prints the names of their deployable composites.
+
+ - Use the following command to run the sample:
+
+ On windows do:
+ java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-domain-management.jar manager.ListDeployables
+
+ On *nix do:
+ java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-domain-management.jar manager.ListDeployables
+
+ - You should see the following output:
+
+ Deployable: {http://store}store
+
+2. List contribution dependencies:
+ --------------------------------
+
+ - The sample reads the SCA metadata for two sample contributions and prints their dependencies.
+
+ - Use the following command to run the sample:
+
+ On windows do:
+ java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-domain-management.jar manager.ListDependencies
+
+ On *nix do:
+ java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-domain-management.jar manager.ListDependencies
+
+ - You should see the following output:
+
+ Contribution: store
+ dependency: assets
+ dependency: store
+ Contribution: assets
+ dependency: assets
+
+3. Add deployables to a domain composite and wire them:
+ -----------------------------------------------------
+
+ - The sample first reads the SCA metadata for three sample contributions, and resolve the artifacts contained in the contributions,
+ includes all their deployable composites in a composite model representing an SCA domain, and then
+ uses several composite builder utilities to configure and assemble and wire them together.
+ Finally it prints the resulting domain composite model, showing service bindings
+ configured with the URIs from the nodes hosting them.
+
+ - Use the following command to run the sample:
+
+ On windows do:
+ java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-domain-management.jar manager.WireComponents
+
+ On *nix do:
+ java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-domain-management.jar manager.WireComponents
+
+ - You should see the following output:
+
+ <?xml version="1.0" encoding="UTF-8"?>
+ <composite name="domain" targetNamespace="http://sample"
+ xmlns="http://www.osoa.org/xmlns/sca/1.0" xmlns:ns1="http://www.osoa.org/xmlns/sca/1.0">
+ <component name="ShoppingCart" uri="ShoppingCart">
+ <implementation.java class="services.ShoppingCartImpl"/>
+ <service name="Cart">
+ <ns2:binding.atom name="Cart" uri="/ShoppingCart/Cart" xmlns:ns2="http://tuscany.apache.org/xmlns/sca/1.0"/>
+ </service>
+ </component>
+ <component name="ShoppingCartClient" uri="ShoppingCartClient">
+ <implementation.java class="services.ShoppingCartClientImpl"/>
+ <service name="Cart">
+ <ns2:binding.atom name="Cart" uri="/ShoppingCartClient/Cart" xmlns:ns2="http://tuscany.apache.org/xmlns/sca/1.0"/>
+ </service>
+ <reference name="cart">
+ <ns2:binding.atom name="cart#ShoppingCart/Cart"
+ uri="/ShoppingCart/Cart" xmlns:ns2="http://tuscany.apache.org/xmlns/sca/1.0"/>
+ </reference>
+ </component>
+ </composite>
+
+4. List Components:
+ -----------------
+
+ - This sample reads the SCA metadata for two sample contributions, and displays their dependencies, reads and resolve
+ the artifacts contained in the contributions, and finally prints the deployables composites and the components
+ they declare as well as their main characteristics (showing that their interfaces and implementations are actually resolved).
+
+ - Use the following command to run the sample:
+
+ On windows do:
+ java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-domain-management.jar manager.ListComponents
+
+ On *nix do:
+ java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-domain-management.jar manager.ListComponents
+
+ - You should see the following output:
+
+ Deployable: {http://store}store
+ component: ShoppingCart
+ componentService: Cart
+ binding: class org.apache.tuscany.sca.binding.atom.impl.AtomBindingImpl - /ShoppingCart/Cart
+ implementation: services.ShoppingCartImpl
+ service: Cart
+ interface: services.Cart
