Olá…
Estou enfrentando um problema com o Jasper… Acredito que seja uma bobagem, mas como não encontrei referências sobre o erro no google, achei que seria uma boa postar aqui.
Minha classe:
[code]import java.sql.ResultSet;
import java.util.HashMap;
import java.util.Map;
import net.sf.jasperreports.engine.JRResultSetDataSource;
import net.sf.jasperreports.engine.JasperExportManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperRunManager;
import net.sf.jasperreports.view.JasperViewer;

public class ImprimeRelatorio {/** Creates a new instance of ImprimeRelatorio */
public ImprimeRelatorio() {
}public void geraRelatorio() throws Exception{
Conexao conn = new Conexao();
ResultSet rs;
try{
rs = conn.relatorioCapitulo();
/* implementação da interface JRDataSource para DataSource ResultSet */
JRResultSetDataSource jrRS = new JRResultSetDataSource(rs);/* HashMap de parametros utilizados no relatório. Sempre instanciados */ Map parameters = new HashMap(); // parameters.put("COLUNA", valor); /* Preenche o relatório com os dados. Gera o arquivo BibliotecaPessoal.jrprint */ JasperFillManager.fillReportToFile("C:/Projetos/NetBeans/Sistema de FSO/build/web/Teste_de_Relatorio.jasper", parameters, jrRS); /* Exporta para o formato PDF */ JasperExportManager.exportReportToPdfFile("C:/Projetos/NetBeans/build/web/Teste_de_Relatorio.jasper.jrprint"); /* Preenche o relatorio e o salva diretamente em arquivo PDF. Sem a necessidade do .jrprint */ //JasperRunManager.runReportToPdfFile("C:/Projetos/NetBeans/build/web/Teste_de_Relatorio.jasper", parameters, jrRS); /* Visualiza o relatório em formato PDF */ JasperViewer.viewReport("C:/Projetos/NetBeans/build/web/Teste_de_Relatorio.pdf", false ); }catch(Exception erro){ System.out.println("gerRelatorio() ----> " + erro); }}
}[/code]
Daí quando eu clico no botão que instancia este objeto, e deveria executar este método, ocorre o seguinte erro:

Daí se alguém souber o que pode ser, fico agradecido.
Valeu galera.
