CalculatorServiceAsyncImplTuscany Samples">CalculatorServiceAsyncImplTuscany SamplesThe Tuscany Samples are shipped with Tuscany binary and source releases. If you are using tuscany from a release distribution then make sure you are looking at the documentation that corresponds to the samples as they stood at the time of the release. 2.0-beta samples documentation If however you are working with a snapshot distribution, or using samples code from the trunk of our source repository, then you've come to the right place, as the documentation here reflects the curtrent status of the samples in the trunk of our source tree. In a distribution, the samples source code is found in either a binary or source code distribution in the samples directory, directly under the root directory. The following sections are laid out to match the structure of the samples directory and its subdirectories.
getting-startedThe basic package of SCA application artifacts is a contribution which for this simple sample is found in contribution-helloworld. There's also a directory which contains all you need to make a web application archive which can be deployed to a web container such as Tomcat, so that the sayHello service can be run in the web container. To see Tuscany in action you must launch a component withing a Tuscany runtime environment. Launching contributions is discussed in the "Running Tuscany" section below. contribution-helloworldIn this folder you'll find the simplest contribution, implemented in Java, that implements the "business logic" of saying hello to a person whose name is supplied as input to the service. This contribution contains Java implementation code offering the service String sayHello(String name), where the implementation of the service prepends "Hello" to the name and prints the result to the console. helloworld-webappTODO It's not at all clear how this is supposed to work once it is in the web container - I have asked on the dev list running-tuscanyRunning something in Tuscany requires one or more contributions, and a method of launching the contributions to make them available as services. The sections below describes various means of launching contributions into an executing tuscany runtime. command-lineTo execute a sample contribution from the command line on Windows, from a command prompt in the samples directory, run the command ... ..\bin\tuscany.bat "contribution-name" for example ..\bin\tuscany.bat contribution-binding-sca-calculator or on *nix platforms, from a shell prompt in the samples directory, run the command ... ../bin/tuscany.sh contribution-binding-sca-calculator embedded-jseThis directory contains sample java launchers for the ant run-<contributionname> where run-<contributionname> is one of the targets in the build.xml file To use this sample launcher to run all of the contributions as junit test cases, execute the command "mvn" in the launcher directory. embedded-osgiThe launchers implemented in the src/main/java/launchers directory each launch a specific contribution into the OSGI runtime. ant run-<contributionname> where run-<contributionname> is one of the targets in the build.xml file To use this sample launcher to run all of the contributions as junit test cases, mvn in the launcher directory. mavenTo execute a sample contribution from Maven look for contributions that have the following configuration in their pom.xml file: <plugin> For contributions that have this, for example, learning-more/binding-sca/contribution-calculator, do the following cd samples/learning-more/binding-sca/contribution-calculator This will launch the contribution in the Tuscany runtime and then wait. At this point you can use osgiThe Tuscany runtime can be run in and OSGi container. Running in Equinox On Windows, run java \-jar ..\..\modules\osgi-3.5.0-v20090520.jar \-configuration ..\..\features\configuration \-clean \-console On *Unix, run java \-jar ../../modules/osgi-3.5.0-v20090520.jar \-configuration ../../features/configuration \-clean \-console You should see the osgi console: osgi> osgi> Jun 22, 2009 1:32:27 PM org.apache.tuscany.sca.extensibility.equinox.EquinoxServiceDiscoveryActivator start INFO: Equinox-based service discoverer is now configured. You can run "ss" command under the osgi> to see the status of the bundles. osgi> ss Then you can install and start contributions as bundles by doing the following: osgi> install file:./path/to/contribution_bundle.jar Note that contribution_bundle.jar will need an activator in order to register the bundle as a SCA contribution see samples/???? Running on Felix See http://tuscany.apache.org/documentation-2x/running-tuscany-sca-2x-with-equinox-and-felix.html shellThis directory contains a sample shell program supporting simple commands to To build the sample shell do this: mvn install To run it: ./sca at the prompt: start myNode ../../applications/store/target/sample-store.jar or: start myNode http://people.apache.org/~jsdelfino/tuscany/java/test/sample-store.jar also try: status stop myNode bye Starting and stopping composites is pretty fast. To see that, try the following ./sca <scripts/test.txt or ./sca <scripts/test-remote.txt The shell can also run as a Webapp. To try it install target/scashell.war in webappTo execute sample webapp based contributions (contributions that have webapp at the end of their name) you For example, for binding-jsonrpc/contribution-calculator-webapp, do the following cd samples/binding-jsonrpc/contribution-calculator-webapp mvn cp target/sample-contribution-binding-jsonrpc-calculator-webapp.war your_container_deployment-dir As an alternative sample webapp based contributions can be run within Jetty directly from Maven, look for <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>maven-jetty-plugin</artifactId> <version>6.1.18</version> </plugin> For contributions that have this, for example, binding-jsonrpc/contribution-calculator-webapp, do the following cd samples/binding-sca/contribution-calculator mvn jetty:run This will launch the contribution in the Jetty runtime and then wait. At this point you can use http://localhost:8080/sample-contribution-binding-jsonrpc-calculator-webapp/ learning-moreThe samples found in the contributions below illustrate how to see more of SCA and Tuscany's features in action. asyncTODO finish documenting This sample demonstrates invocation of services offered in both synchronous and asynchronous forms. Asynchroncity is possible by either callback to or polling by the original service invoker. sample-contribution-implementation-java-calculator-async">sample-contribution-implementation-java-calculator-asyncIn the composite file src/main/resources/Calculator.composite the references "calculatorServiceRefSync" and "calculatorServiceRefAsync" make use of the alternative implementations of the Calculator service described in the CalculatorSync and CalculatorAsync components and implemented in the calculator.CalculatorServiceSyncImpl and calculator.CalculatorServiceAsyncImpljava classes. embedded-jse-async-sample-launcherNote that the launcher simply starts and stops a node running the contribution. Within the contribution the CalculatorClient java class, marked with the @EagerInit annotation, runs its calculate method (marked with the @Init annotation), thereby triggering the calculation service to be performed. The calculator service is actually performed by the injected instance of CalculatorServiceProxyImpl, which uses both of its references (one for the sync service, one for the async) to perform calculations. The calculations are then performed by instances of CalculatorServiceSyncImpl and CalculatorServiceAsyncImpl. Note that the Tuscany runtime views the following two interfaces as compatible. @Remotable Unknown macro: { String calculate(Integer n1);}{code}
@Remotable public interface CalculatorService Unknown macro: {
String calculate(Integer n1);
}
@Remotable @AsyncInvocation public interface CalculatorServiceAsync Unknown macro: {
void calculateAsync(Integer n1, ResponseDispatch<String> response);
}
h3. binding-comet {note:title=TODO} {color:#000000}Understand and Document{color} {note} h3. binding-jsonrpc This sample demonstrates using a simple calculator service component which makes use of four services for the basic arithmetic functions. In this variant of the calculator sample you can see by looking in the src/main/resources/Calculator.composite xml file that the AddService is configured to be invoked using the json rpc protocol. h4. contribution-calculator {note:title=TODO} {color:#000000}Understand and Document{color} {note} h4. contribution-calculator-webapp {note:title=TODO} {color:#000000}Understand and Document{color} {note} h3. binding-rmi In this example the caluclator function is split over two contyributions in order to demonstrate the remote method invocation binding. {note:title=TODO} {color:#000000} Document{color} {note} h4. contribution-calculator-reference {note:title=TODO} {color:#000000} Document{color} {note} h4. contribution-calculator-service {note:title=TODO} {color:#000000}Document{color} {note} h3. binding-sca {note:title=TODO} {color:#000000}Understand and Document{color} {note} h4. contribution-calculator {note:title=TODO} {color:#000000}Understand and Document{color} {note} h3. binding-ws {note:title=TODO} {color:#000000}Understand and Document{color} {note} h4. contribution-calculator h4. contribution-helloworld-ws-sdo {note:title=TODO} {color:#000000}Understand and Document{color} {note} h3. distributed-osgi These samples demonstrate the execution of Tuscany contributions in a distributed OSGI environment. h4. dosgi-dynamic-calculator h4. dosgi-dynamic-calculator-operations h3. implementation-bpel {note:title=TODO}{note} h4. contribution-helloworld-bpel {note:title=TODO}check instructions work and fix up{note} This sample demonstrates an SCA service implemented by a BPEL process.
