TOTD #12: Invoking a Java EE 5 Web service endpoint from JRuby

A user asked how to invoke a Java EE 5 Web service from JRuby. This TOTD explains how a simple Metro Web service deployed on GlassFish V2 can be easily invoked from JRuby.

Create a simple Web service using NetBeans IDE and deploy it on GlassFish V2 following the screencast #ws7.
Generate the client-side artifacts using wsimport as shown below:

C:\workarea\samples\jruby\ws>\testbed\glassfish\final\glassfish\bin\wsimport.bat -keep http://localhost:8080/WebApplication32/HelloService?wsdl parsing WSDL... generating code... compiling code...
Set the CLASSPATH in the command prompt as shown below:

C:\workarea\samples\jruby\ws>set CLASSPATH=.;\testbed\glassfish\final\glassfish\lib\webservices-rt.jar;\testbed\glassfish\final\glassfish\lib\endorsed\webservices-api.jar;C:\testbed\glassfish\final\gl assfish\lib\activation.jar
Use the JRuby code to invoke the Web service endpoint as shown below:

include Java service = Java::server.HelloService.new(); port = service.getHelloPort(); result = port.sayHello("Duke"); java.lang.System.out.println(result);
Invoke the JRuby code as shown below:

C:\workarea\samples\jruby\ws>\testbed\ruby\jruby-1.0.1\bin\jruby simple.rb Hello Duke
