It uses +exactly the same calculator application classes as the calculator sample but +runs the application distributed across three nodes. + +A node in this sample means an instance of the Tuscany SCA java runtime running +in a Java virtual machine. + +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 four command prompts and +navigate to this sample directory in each one. There is one command to be run +in each command prompt: + +ant runDomain +ant runNodeB +ant runNodeC +ant runNodeA + +Please run the commands in this order. + +OR if you don't have ant, on Windows use + +java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchDomain +java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchCalculatorNodeB +java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchCalculatorNodeC +java -cp src\main\resources;..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-distributed.jar node.LaunchCalculatorNodeA + +and on *nix do + +java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchDomain +java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchCalculatorNodeB +java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchCalculatorNodeC +java -cp src/main/resources:../../lib/tuscany-sca-manifest.jar:target/sample-calculator-distributed.jar node.LaunchCalculatorNodeA + +The processes started on each of these command prompts can be ended by typing 'q'. + + +Sample Overview +--------------- +The sample provides a single calculator service with a default SCA (java) +binding. NodeA exercises this interface by calling add, subtract, multiply and +divide operations. + +In the case of add and subtract the runtime recognises that +it can't find these services locally and, using the remote (web services) +version of the default SCA binding, contacts the add service running in NodeB +and the subtract service running in NodeC. + +On the command prompt where you started NodeA, you see the output of invoking the +calculator functions distributed over NodeB and and NodeC. On the command prompts +where you have started NodeB and NodeC, you see log messages that indicate that +the add and subtract services where called on these nodes respectively. + +The sample demonstrates that the calculator application can be distributed +across multiple nodes with no change to the application or to the SCA description +files. + +The domain node makes available a web application through which the contributions and +composites used in this sample can be navigated. One you have run "ant runDomain" you can +point you browser at: + +http://localhost:9990/ui/workspace/ + +The contents of the sample are as follows: + +calculator/ + src/ + main/ + java/ + calculator/ + CalculatorService.java - the first component, calls +-/* as + appropriate + AddService.java - adds two numbers + AddServiceImpl.java + SubtractService.java - subtracts one number from another + SubtractServiceImpl.java + MultiplyService.java - multiplies two numbers + MultiplyServiceImpl.java + DivideService.java - divides one number by another + DivideServiceImpl.java + node/ + LaunchCalculatorNodeA.java - runs an sca node configured with the + composite describing the main calculator + application. If you look inside this class + you will see that the node is configured + using a URL of the form: + + http://localhost:9990/node-config/NodeA + + This retrieves the information required + to configure NodeA from the domain. + + Once the node has been started this launcher + then finds the calculator service and + calls the various methods. + + LaunchCalculatorNodeB&C.java - These launchers start nodes B and C + which runs the add and subtract services. + + Unlike NodeA though these launchers just + wait once the node has been started. They + will service incomming web service requests + as they arrive. + + LaunchDomain.java - the node that provides the domain + configuration to the distributed + nodes + resources/ + cloud - The SCA composite files that describe + the configuration of each node + nodeA - the SCA assembly for nodeA's part of the + calculator application + nodeB - the SCA assembly for nodeB's part of the + calculator application + nodeC - the SCA assembly for nodeC's part of the + calculator application + test/ + java/ + calculator/ + CalculatorDistributedTestCase.java - JUnit test case which runs all + of the separate nodes along with the domain + in a single VM for test purposes + calculator-distributed.png - a pictorial representation of the sample + .composite files + build.xml - the Ant build
