RESUMO:[color=red] ERRO AO CHAMAR O RELATORIO[/color]
Passos feitos:
- Primeiramente instalei o iReport-3.7.2 ficando armazenado na seguinte pasta: C:\Arquivos de programas\Jaspersoft\
- Na pasta "modules" localizada em C:\Arquivos de programas\Jaspersoft\iReport-3.7.2\ireport\modules encontra-se todos os jars necessarios como: jasperreports-3.7.2, log4j-1.2.15, commons-logging-1.1 , [...] entre outros)..
- eu fiz uma copia dessa pasta "modules" localizada em C:\Arquivos de programas\Jaspersoft\iReport-3.7.2\ireport\modules para a pasta raiz do meu projeto;
- no netbeans eu adicionei todos os jars localizados na pasta "MODULES" que estar na pasta raiz do meu projeto....
