Estou com problema na hora de chamar o relatorio, ja fiz vario deles mas esse estou quebrando a cabeça;
parte do metodo, estou chamando pelo resultset.
InputStream input = getClassLoader().getResource(arquivo).openStream();
JasperPrint print;
if(data != null)
print = JasperFillManager.fillReport(input, parametros, data); -----> [size=18][b]Esta dando o erro na hora dessa chamada;[/b][/size]
else
print = JasperFillManager.fillReport(input, parametros,getConexao());
Erro que esta dando
java.lang.NullPointerException
