Calculator Sample ================= This sample uses the same code as the calculator sample but deploys the sample wrapped in a web app. The README in the samples directory (the directory above this) provides general instructions about building and running samples. Take a look there first. As this sample provides a web app there is a manual step where the WAR file that contains the sample is copied to your web app container. If you just want to give this sample a go deploy the WAR file (target/sample-calculator-web.war) to you web application server. Once the web app is deployed use your browser to visit the following URL; http://localhost:8080/sample-calculator-web The port and hostname will of course vary depending on your local installation. Sample Overview --------------- The sample provides a single calculator service with a default SCA (java) binding. The CalculatorClient exercises this interface by calling add, subtract, multiply and divide operations. This results in messages passing to the appropriate components in the composite across the local wires. calculator-web/ src/ main/ java/ calculator/ CalculatorService.java - As calculator sample AddService.java - As calculator sample SubtractService.java - As calculator sample MultipleService.java - As calculator sample DivideService.java - As calculator sample CalculatorClient.java - As calculator sample resources/ Calculator.composite - As calculator sample webapp WEB-INF/ web.xml - defines the listener that starts up the Tuscany SCA runtime calc.jsp - the web application that makes use of the SCA application calculator.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 ----------------------------------------- With the binary distribution the sample can be built using Ant as follows cd calculator-web ant package This should result in a war file (sample-calculator-web.war) in the target directory. Copy this war file to your web app deployment directory in you web app container. The process for getting the web app running will depend on which web app container you are using. For example, if you are using Tomcat then it is simply a matter of copying the WAR file to the webapps directory. Once the web app is deployed use your browser to visit the following URL; http://localhost:8080/sample-calculator-web/calc.jsp The port and hostname will of course vary depending on your local installation. You should see the following output. Expression Result 2 + 3 5.0 3 - 2 1.0 3 * 2 6.0 3 / 2 1.5 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 calculator-web mvn Again this should result in a war file (sample-calculator-web.war) in the target directory. Follow the steps described in the previous section for running the web app and for the expected results.
