iReport - Problema com caminho do jasperfile (RESOLVIDO)

Programação Java
#21

Opa, Estou com o mesmo problema e tentei a solução acima.

Mas fiquei com uma dúvida: qual o retorno da chamada da classe em

relatorio = JasperFillManager.fillReport(jasperReport, parametros, new RelatorioPrecipitacoesDS());

Pois eu coloquei um retorno de JRResultSetDataSource pois eu edito a SQL do Jasper e não está dando certo.

Valeu

os caminhos estao la e estao corretos

InputStream jasperFile = getClass().getResourceAsStream( “/Relatorios//relatorio.jasper” );

na dist tem o jar
e a pasta dos relatorios
/Relatorios//relatorio.jasper

#24

/Relatorios/relatorio.jasper
