Hello World Web Service SDO WebApp Sample ========================================= This sample demonstrates an SCA web service binding which works with SDO and runs as a web application. 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 is built and copied to your web app container. See the sections below for instructions on building the war. Once the web app is deployed use your browser to visit the following URL; http://localhost:8080/sample-helloworld-ws-sdo-webapp The port and hostname will of course vary depending on your local installation. The resulting web page displayed should show: Hello John Smith, Jane Doe! Sample Overview --------------- The sample builds a war with a single JSP (HelloWorld.jsp). This JSP calls an SCA component with an SDO parameter. This in turn calls another SCA component with the SDO parameter. The contents of the SDO are then returned as a simple string. This sample shows how SDO objects can be passed into and between services in the context of a web application. helloworld-jsonrpc-webapp/ src/ main/ java/ helloworld/ HelloWorld.java - service interface HelloWorldComponent.java - first service implementation HelloWorldmpl.java - second service implementation resources/ wsdl/ helloworld.wsdl - the web services description helloworld.xsd - the SDO description helloworldws.composite - the SCA assembly for this sample 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 HelloWorld.jsp - the web application that calls the SCA service passing in an SDO helloworld-ws-sdo-webapp.png - a pictorial representation of the sample .composite file build.xml - the Ant build file pom.xml - the Maven build file Building The Sample Using Ant ----------------------------------------- With the binary distribution the sample can be built using Ant as follows cd helloworld-ws-sdo-webapp ant package This should result in a war file (sample-helloworld-ws-sdo-webapp.war) in the target directory. Copy this war file to your web app deployment directory in your 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-helloworld-ws-sdo-webapp The port and hostname will of course vary depending on your local installation. Building The Sample Using Maven ------------------------------- With either the binary or source distributions the sample can be built and run using Maven as follows. When using Maven you don't need to run the helloworld- ws-service sample first as Maven does this for you. cd helloworld-ws-sdo-webapp mvn That should end with "BUILD SUCCESSFUL" and create the target/sample-helloworld-ws-sdo-webapp.war which you can copy to your server.
