Dúvida JasperReports e iReport

Debugger Membro desde: 25/05/2006 16:43:41 Mensagens: 60 Offline

Pessoal,

Eu estou fazendo relatórios usando JasperReports e a ferramenta iReport para desenhar, consigo gerar os arquivos: .jasper, .jrprint e inclusive o .pdf (que é o resultado final) ele é gerado e os dados estão todos corretos, consigo abrir ele indo até o diretório em que se encontra.

O meu problema está ao tentar mostrar esse relatório através da minha aplicação, quando tento isso, resulta no seguinte erro:

A classe para gerar o relatório é a seguinte:

package br.com.sistema.relatorios;

import java.sql.ResultSet;
import java.util.HashMap;
import java.util.Map;

import br.com.sistema.control.ClienteFisicoControl;
import br.com.sistema.util.PathAplicacao;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRResultSetDataSource;
import net.sf.jasperreports.engine.JasperExportManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.view.JasperViewer;

public class TesteJasper {
	
	public void metodo(){			
		
		ClienteFisicoControl control = new ClienteFisicoControl();
		ResultSet rs = control.listOrdemCidadeRelatorio();
		
		/* implementação da interface JRDataSource para DataSource ResultSet */
		JRResultSetDataSource jrRS = new JRResultSetDataSource( rs );
		/* HashMap de parametros utilizados no relatório. Sempre instanciados */
		Map<String, String> parameters = new HashMap<String, String>();
		
		/* Preenche o relatório com os dados. Gera o arquivo BibliotecaPessoal.jrprint */
		try {
			JasperFillManager.fillReportToFile( PathAplicacao.getPath("relatoriosjasper") + "ClientesFisicos.jasper", parameters, jrRS );
			/* Exporta para o formato PDF */
			JasperExportManager.exportReportToPdfFile( PathAplicacao.getPath("relatoriosjasper") + "ClientesFisicos.jrprint" );
			
			/* Visualiza o relatório em formato PDF */
			JasperViewer.viewReport( PathAplicacao.getPath("relatoriosjasper") + "ClientesFisicos.pdf", false );
		} catch (JRException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}		
	}
}

O problema está na linha:
JasperViewer.viewReport( PathAplicacao.getPath("relatoriosjasper") + "ClientesFisicos.pdf", false );

Obs.: estou chamando este método através de um JMenuItem dentro de uma classe JFrame.

Desde já agradeço

Consegui resolver o problema.

Na linha em que tinha o problema, deve ser trocado o tipo do arquivo, ao invés de tentar abrir o .pdf, devo tentar abrir o .jrprint, ai então vai abrir a janela com o relatório e depois é possível salvá-lo com outra extensão.

A linha correta é a seguinte:

Pessoal.....
Preciso urgênte de uma ajuda......

Estou utlizando o JasperViewer para visualização do meu relatório. Eu não posso deixar o usuário imprimir, ou seja, tenho que desabilitar ou sumir com a impressora.
Alguém tem alguma idéia.
