This binding supports communication over the JSON-RPC protocol.
calculator-contribution
...
This sample demonstrates using the simple calculator service component which makes use of four other services for add, subtract, multiply and divide functions. In this variant of the calculator sample the AddService is configured to be invoked using the JSON-RPC protocol. You can see the configuration by looking in the src/main/resources/Calculator.composite xml file.

calculator-contribution
The service and reference definitions in the Calculator.composite and CalculatorClient.composite files have no binding attributes, thereby defaulting to the SCA binding for communication between the running instances of the components.
binding-ws
This sample contains contrributions which show how the services can be offered via a web service interfaqce.
contribution-calculator (for binding-ws)
This contribution provides the four arithmetic operations in the calculator service, with the AddService being accessible as a web service via the URL http://localhost:8085/AddServiceComponent, as configured in the Calculator.composite file in the contribution project.

contribution-helloworld-ws-sdo
This sample demonstrates an SCA reference that uses a web service binding which works with SDO. Instead if using JAXB style Java beans in the service interface they are replaced with SDO object.

| Hello World Web Service References using SDO Sample =================================================== This sample demonstrates an SCA reference that uses a web service binding which works with SDO. The README in the samples directory (the directory above this) provides general instructions about building and running samples. Take a look there first. To run this sample ------------------ This sample is dependent on helloworld-ws-service. Open a command prompt to start the service. If you are running ant do the following: cd helloworld-ws-service ant run if you don't have ant, issue one of the following commands for windows or *nix: java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-helloworld-ws-service.jar helloworld.HelloWorldServer and on *nix do java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-ws-service.jar helloworld.HelloWorldServer You should see the following output: Buildfile: build.xml run-server: [java] log4j:WARN No appenders could be found for logger (org.apache.axiom. om.util.StAXUtils).

[java] Injected helloWorldService [java] Called getGreetings [java] Hello David Haney BUILD SUCCESSFUL Total time: 9 seconds Sample Overview --------------- The sample provides a single component that is wired to a reference with a web service binding. The binding refers to WSDL that identifies the service exposed by the helloworld-ws-service sample. helloworld-ws-sdo/ src/ main/ java/ helloworld/ HelloWorldService.java - interface description for HelloWorldServiceComponent HelloWorldServiceComponent.java - component implementation HelloWorldClient.java - starts the SCA Runtime and deploys the helloworldwsclient .composite. It then calls the HelloWorldServiceComponent resources/ wsdl helloworld.wsdl - the service description that the SCA reference uses to bind to service. test/ java/ helloworld/ HelloWorldClientTestCase.java - JUnit test case helloworld-ws-sdo.png - a pictorial representation of the sample .composite file build.xml - the Ant build file pom.xml - the Maven build file Building And Running The Sample Using Ant ----------------------------------------- You can build and run the sample with the binary distribution using Ant. Make sure that you have started helloworld-ws-service which this sample is dependent on in a separate command window. You can either follow the instruction at the begining of this sample file or if you want to build and run the service, follow the README under helloworld-ws-service. Now, let's build and run helloworld-ws-sdo sample: cd helloworld-ws-sdo ant ant run You should see the following output from the run target. run: [java] log4j:WARN No appenders could be found for logger (org.apache.axiom. om.util.StAXUtils). [java] log4j:WARN Please initialize the log4j system properly. [java] Injected helloWorldService [java] Called getGreetings [java] Hello World Building And Running The Sample Using Maven ------------------------------------------- You can build and run the sample with either the binary or source distributions using Maven. Please note that you do not need to start helloworld-ws-service in this case since Maven does this for you. cd helloworld-ws-sdo mvn You should see the following output from the test phase. ------------------------------------------------------- T E S T S ------------------------------------------------------- Running helloworld.HelloWorldClientTestCase log4j:WARN No appenders could be found for logger (org.apache.axiom.om.util.StAX Utils). log4j:WARN Please initialize the log4j system properly. log4j:WARN No appenders could be found for logger (org.apache.axiom.om.util.StAX Utils). log4j:WARN Please initialize the log4j system properly.

distributed-osgi
These samples demonstrate the execution of Tuscany contributions in a distributed OSGI environmentOSGI environment. In particular the two projects in this directory define calculator objects that communicate with one another using the mechanisms defined in the OSGi remote services specifications. Here the Tuscany SCA runtime provides dynamic service discovery functionality. The calculator objects are registered as services directly with the OSGi bundle context by the bundle activator. Under the covers SCA provides the remote service disovery features that allow OSGi registered service to discover and communicate with one anothe across two JVMs.
