F�rum Curso de iReport - Desenvolvendo Relat�rios com Java - Aula 49 #547083

28/02/2016

Gostaria de saber como gerar mais um relat�rio nessa aplica��o. Criei uma nova Servlet seguindo os passos do exemplo do curso que tem na Servlet "RelatorioServlet" a url de acesso "relat�rio" criei uma nova Servlet: "FolgaServlet" com a url de acesso "folga" mas n�o executa. Algu�m poderia me ajudar?

* Quando eu uso a "FolgaServlet" com url de acesso "relatorio", funciona. O que tem a ver o nome dado para URL?

package br.edu.servlet; import java.io.IOException; import java.sql.SQLException; import java.util.HashMap; import java.util.Map; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import net.sf.jasperreports.engine.JRException; import net.sf.jasperreports.engine.JasperExportManager; import net.sf.jasperreports.engine.JasperFillManager; import net.sf.jasperreports.engine.JasperPrint; import br.edu.conexao.ConexaoUtil; /** * Servlet implementation class FolgaServlet */ @WebServlet("/Folga") public class FolgaServlet extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#service(HttpServletRequest request, HttpServletResponse response) */ protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String pathRelatorios = getServletContext().getRealPath("/relatorios/") + "\\"; Map parametros = new HashMap<>(); parametros.put("SUBREPORT_DIR", pathRelatorios + "\\"); try { JasperPrint jasperPrint = JasperFillManager .fillReport(pathRelatorios + "report_subreport_folga.jasper", parametros, ConexaoUtil.getConexao()); JasperExportManager.exportReportToPdfStream(jasperPrint, response.getOutputStream()); } catch (ClassNotFoundException | JRException | SQLException e) { e.printStackTrace(); } } }
