Programação Java
#1

Olá pessoal, td blzz.

Qdo chamo o JSP, o tomcat me retorna um erro q está logo abaixo:

[code]HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 37 in the jsp file: /jsp/html.jsp

O código JSP q estou usando é este:

[code]<%@ page errorPage=“error.jsp” %>
<%@ page import=“datasource." %>
<%@ page import="net.sf.jasperreports.engine.” %>
<%@ page import=“net.sf.jasperreports.engine.util." %>

<%@ page import=“java.util." %>
<%@ page import="java.io.” %>
<%
File reportFile = new File(application.getRealPath("/reports/usuarios.jasper"));

JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());

Map parameters = new HashMap();
parameters.put("ReportTitle", "Address Report");
parameters.put("BaseDir", reportFile.getParentFile());
			
JasperPrint jasperPrint = 
	JasperFillManager.fillReport(jasperReport,parameters,new WebappDataSource());
			
JRHtmlExporter exporter = new JRHtmlExporter();

StringBuffer sbuffer = new StringBuffer();

Map imagesMap = new HashMap();
session.setAttribute("IMAGES_MAP", imagesMap);

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, imagesMap);
exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "image.jsp?image=");

exporter.exportReport();

datasource.WebappDataSource implementa JRDataSource?

#3

sim

#4 
JasperPrint jasperPrint = 
 		JasperFillManager.fillReport(jasperReport,parameters,new WebappDataSource());

Mostra o código da tua class WebappDataSource. Por alguma coisa ela está interferindo na assinatura do método que deveria (pro seu caso) ser assim:

public static JasperPrint fillReport(JasperReport jasperReport,
java.util.Map parameters,
JRDataSource dataSource)
throws JRException

#5

Se vc estiver trabalhando com ResultSet pq não utiliza JRResultSetDataSource(java.sql.ResultSet rs) ?

#6

[code]package datasource;

import java.sql.;
import net.sf.jasperreports.engine.;

    public class WebappDataSource

Marcelo, tuh nao tinha falado q a sua classe WebappDataSource implementava JRDataSource???

#8

Certo, vc tem algum exemplo mais simples q eu possa utilizar pra se conectar no oracle e exibir o *.jasper no browser.
