Pessoal, alguém usa JasperResponse para os relatórios?

Passos usados:
1) Criei o arquivo no iReport.
2) Criei 3 parâmetros no arquivo
3) estou chamando o arquivo passando os parâmetros no controller:
params.parametro1 = parametro1
params.parametro2 = parametro2
params.parametro3 = parametro3

params.jasperSourceName='/reports/relatorioTeste'
render params as Jasper

Está dando o erro abaixo:
