Plugin development

[Jorge Nicolás Mikitiuk]

Hi:
What's the way to add java beans in the plugin.jelly?,
I tried to do it, but Maven send the next message:
    __  __
   |  \/  |__ _Apache__ ___
   | |\/| / _` \ V / -_) ' \  ~ intelligent projects ~
   |_|  |_\__,_|\_/\___|_||_|  v. 1.0.2

   BUILD FAILED
   No goal [eee:jjj]
   A plugin has attempted to use a goal that does not exist
   Total time: 1 seconds
   Finished at: Fri Aug 19 11:01:44 GMT-03:00 2005


It's my plugin.jelly:

   <?xml version="1.0"?>

   <project xmlns:define="jelly:define">
       <goal name="eee" prereqs="eee:uno" description="Default"/>
      
       <goal name="eee:uno" prereqs="eee:jjj" description="Any goal">
              <echo>Algo</echo>
       </goal>
      
       <define:jellybean name="jjj"
   className="ar.com.experience.eee.HelloWorld" method="method"/>
   </project>

Thanks,
