Groovy tutorial in dev guide

Hi I tried to follow the Groovy Tutorial given in the developer guide. But I couldn't make it run. (http://www.xwiki.org/xwiki/bin/view/DevGuide/GroovyClassHelloWorldTutorial) Instantiating groovy class from velocity threw the foll error : Error number 4001 in 4: Error while parsing velocity page Main.HelloWorldFromVelocity Wrapped Exception: Invocation of method 'parseGroovyFromPage' in class com.xpn.xwiki.api.XWiki threw exception com.xpn.xwiki.XWikiException: Error number 14001 in 14: Failed compiling groovy script Wrapped Exception: startup failed, script1177398554781.groovy: 5: unexpected token: xwiki @ line 5, column 5. Instantiating groovy from groovy resulted in the foll error : Error number 4002 in 4: Error while parsing groovy page Groovy.HelloWorldClassTest Wrapped Exception: startup failed, Script1.groovy: 3: unexpected token: groovyObject @ line 3, column 68. (While creating the class I have assigned programming rights to the user who made the class.) What am I doing wrong. Thanks and Regards Roopesh
