Nó, tá quase !!! hehehehe
Reorganizei meus pacotes, agora a pasta REPORTS (renomeei tb por desencargo) está logo abaixo da pasta WebContents e ele agora está localizando (Ufa)
Meu código ficou assim :
public void geraFichaFiliacao(Connection con,File file) throws JRException {
sb = new StringBuffer();
try {
sb.append("select * from filiacao");
stmt = con.prepareStatement(sb.toString());
rs = stmt.executeQuery();
JRResultSetDataSource jrRS = new JRResultSetDataSource(rs);
Map parameters = new HashMap();
String extensaoJasper = ".jasper";
String extensaoJrprint = ".jrprint";
String extensaoPdf = ".pdf";
JasperFillManager.fillReportToFile(file.getPath()+ extensaoJasper,
parameters,jrRS);
JasperExportManager.exportReportToPdfFile(file.getPath()+ extensaoJrprint);
JasperViewer.viewReport(file.getPath()+ extensaoPdf, false);
} catch (NullPointerException en) {
en.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
Ele tá gerando o PDF mas não me mostra e aparece o seguinte erro :

Eu sei que ele está gerando o PDF corretamente pois consigo ver o arquivo gerado lá no C:\Sun\JAVA.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\sindieletro\reports\filiacao.pdf
Alguem tem ideia do que pode estar acontecendo ?
Tô quase !
vimieiro
Ah, colega Adriano, infelizmente não consegui fazer aquele código seu que gera o PDF em tempo de execução (
