19.8. HelloWorld Example: Rule "Good Bye"

rule "Good Bye"
      dialect "java"
  when
      Message( status == Message.GOODBYE, message : message )
  then
      System.out.println( message ); 
end

The "Good Bye" rule, which specifies the "java" dialect, is similar to the "Hello World" rule except that it matches Message objects whose status is Message.GOODBYE
