Hi all;

when you run the maven , it will create the groovey service as 
"modules\samples\target\samples\groovyService.aar" , small decription about 
service given by service developers (Thyaparan , Tharshitha , Sahan) as 
follows

We have come up with the new service,implemented in Groovy 
(http://groovy.codehaus.org/); which is a dynamic, agile, scripting language 
based on the JVM. It is able to take an inputStream as an argument from the 
Message Receiver Class which is in Java. Then it can process the inputStream 
and return back an XML-file as a StringWriter, which we can print out in the 
Java Class.
