Tuscany Hello World Web Sample

+ + + +

Overview

+ + + +

The Tuscany hello world web sample shows using the Tuscany SCA + runtime in a Tomcat environment being accessed from a JSP + page that + implements the classic introductory hello world example.

+

Location

+This sample is located  in the samples\sca\helloworldweb directory. + + + +

Setup

+ +Set up your server as described in the Tomcat Setup.   + +If you are not using the pre-configured Tomcat server from the binary distribution, you will need to add sample-helloworldweb-incubating-M1.war to your tomcat's webapp directory.
+ + + +

Running

+ + + +Once you've started your web server, use your browse to view the +following URL: http://localhost:8080/sample-helloworldweb/ +
+ + + +You should see a form you can supply your name and a submit button. + Once you submit the form the JSP page calls a Java class that +gets the CurrentModuleContext and locates the SCA component to execute +the greeting service.  Note, unlike the a J2SE in a Tomcat environment the Tuscany runtime is automatically +initialized and running. +

Results

+ + + +

The page should be updated with the greeting displayed below + the form.
+ + + +

sca.moduleDefines the SCA module and component. Defines for the + HelloWorldServiceComponent component and the Java class that + implements that component
HelloWorldService.javaDefines the Java interface implemented by the component.
HelloWorldImpl.javaImplements the SCA component. Uses the SCA service + annotation tag on the class to show what SCA interface is being + implemented.
HelloWorldWeb.jspHandles Web form input.. Obtains the module context which was defined by the + sca.module file. From the module context locates the + HelloWorldServiceComponent and then calls  the getGreetings + method to invoke the component. and formats  returned results.
