Problema com IReport | Solucionado

Olá estou com o seguinte problema com ireport.

Minha classe para gerar o arquivo é:

public class RelatorioPacienteService {

    public void gerarRelatorio(List<Paciente> pacientes){

        try {
            JasperReport report = JasperCompileManager.compileReport("relatorios/relatorioPaciente.jrxml");
            JasperPrint print = JasperFillManager.fillReport(report, null,new JRBeanCollectionDataSource(pacientes));
            JasperExportManager.exportReportToPdfFile(print,"relatorios/RelatorioClientes.pdf");
        } catch (JRException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

O erro que aparece no console é:

Alguém saberia me informar o porque?

Obs.: O relatório está na linguagem java, alterei no arquivo quando estava no ireport.
