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-ws-webapp.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-ws-webapp + +The sample is configured to use a service on port 8080. If your servlet container +is using a port other than 8080 then you will need to edit the Calculator.composite +and change the uri attribute of the <binding.ws> used by the CalculatorServiceComponent +to use the correct port. + +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. + +calculator-webapp/ + src/ + main/ + java/ + calculator/ + AddService.java - As calculator sample + AddServiceImpl.java + CalculatorClient.java - As calculator sample + CalculatorService.java - As calculator sample + CalculatorServiceImpl.java + DivideService.java - As calculator sample + DivideServiceImpl.java + MultiplyService.java - As calculator sample + MultiplyServiceImpl.java + SubtractService.java - As calculator sample + SubtractServiceImpl.java + resources/ + Calculator.composite - As calculator sample except that the + connection between the CalculatorService + and the AddService is web services + webapp + META-INF/ + sca-contribution.xml - specifies the composite to be deployed + WEB-INF/ + web.xml - defines the listener that starts up the + Tuscany SCA runtime and maps service + calls to the TuscanyServlet + 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 + README - this file + +Building And Running The Sample Using Ant +----------------------------------------- +With the binary distribution the sample can be built using Ant as +follows + +cd calculator-ws-webapp +ant package + +This should result in a war file (sample-calculator-ws-webapp.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-ws-webapp + +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-ws-webapp +mvn + +Again this should result in a war file (sample-calculator-ws-webapp.war) in the target +directory.
