Olá pessoal, estou com dificuldades em visualizar um relatorio e não consigo encontrar o erro.
ele chega a ser gerado, mais não visualiza.
Segue o codigo e o erro:
RelatorioUsuarioHandler
public class RelatorioUsuarioHandler {
public JasperPrint relatorioUsuario() throws JRException {
try {
String arquivoJasper;
// arquivoJasper = "/relatorios/Usuario.jasper";
arquivoJasper = "/relatorios/Usuario.jrxml";
System.out.println("Opening file report...");
InputStream is = RelatorioUsuarioHandler.class
.getResourceAsStream(arquivoJasper);
System.out.println("File open.");
JasperReport jr = JasperCompileManager.compileReport(is);
JRResultSetDataSource jrrs = new JRResultSetDataSource(relatorioDao
.getUsuarios());
Map param = new HashMap();
JasperPrint print = JasperFillManager.fillReport(jr, param, jrrs);
JasperViewer.viewReport(is, false);
return print;
} catch (Exception e) {
System.out.println("Erro Relatorio UsuarioHandler "
+ e.getMessage());
e.printStackTrace();
return null;
}
}
}RelatorioDao
public class relatorioDao {
public static ResultSet getUsuarios() {
System.out.println("Executando query Relatorio...");
String sql = "select id_usuario, login_usuario, nivel_usuario, nome_usuario from usuario";
ResultSet rsRelatorio = null;
try {
System.out.println("Abrindo connection...");
Connection con = HibernateUtil.getConection();
PreparedStatement ps = con.prepareStatement(sql);
rsRelatorio = ps.executeQuery();
} catch (Exception e) {
System.out.println("Erro relatorioDAO " + e.getMessage());
e.printStackTrace();
}
return rsRelatorio;
}
