Grails - grails.converters.JSON - removing the class name

Is there a way to remove the class field in a JSON converter?

Example: 

import testproject.*
import grails.converters.*  
emp = new Employee()  
emp.lastName = "Bar"  
emp as JSON

as a string is 

{"class":"testproject.Employee","id":null,"lastName":"Bar"}

I'd prefer 

{"id":null,"lastName":"Bar"}

Is there a way to add one more line of code at the end to remove the class field?

You can customize the fields to be excluded (including the class name) using the setExcludes method provided in the grails.converters.JSON

def converter = emp  as JSON
converter.setExcludes(Employee.class, ["class",""])

and then, you can use it just like according to your requirements, 

println converter.toString()
converter.render(new java.io.FileWriter("/path/to/my/file.xml"))
converter.render(response)
