Boa tarde,
estou com um problema na hora de chamar relatórios jasper na minha aplicação java.
public static void abrirRelatorioJasper & # 40 ; java . io . FileInputStream arquivoJasper , java . util . HashMap mapParametros & # 41 ; throws dori . jasper . engine . JRException , JRException & # 123 ;
dori . jasper . engine . JasperPrint jPrint = dori . jasper . engine . JasperFillManager . fillReport & # 40 ; arquivoJasper , mapParametros , Conexao . getConnection & # 40 ; & # 41 ; & # 41 ;;
dori . jasper . view . JasperViewer . viewReport & # 40 ; jPrint , false & # 41 ;;
& # 125 ;
na hora de chamá-lo na aplicação aparece a mensagem:
java . lang . ClassCastException : net . sf . jasperreports . engine . JasperReport

quando eu clico na linha
at dori . jasper . engine . JasperFillManager . fillReport & # 40 ; JasperFillManager . java & # 58 ; 207 & # 41 ;
abre a classe JasperFillManager.class com a mensagem
e no Class File Editor:
