EU SOU INICIANTE EM JAVA ESTOU TENTANDO APRESENTAR UM RELATORIO A PARTIR DE UM SERVLET ESTOU USANDO O IREPORT PARA GERAR O XML E O JASPER REPORTS PARA GERAR O PDF EU USO UM CODIGO DA SEGUINTE FORMA NO MEU SERVLET

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{

SetaConexao sccac = new SetaConexao(“cac”);
DespachoBean desp = new DespachoBean();

desp.setNumero_matricula(Integer.parseInt(request.getParameter(“matricula”)));
desp.consultaDespachado();
rs = desp.getResultado();
try{
rs.next();
}catch (SQLException e){
e.printStackTrace();
}

JRResultSetDataSource jrRS = new JRResultSetDataSource(rs);
HashMap parametro = new HashMap();
try{
JasperFillManager.fillReportToFile(“teste.jasper”, parametro, jrRS );
JasperExportManager.exportReportToPdfFile(“teste.jrprint”);
JasperViewer.viewReport(“teste.pdf”,false);
}catch (JRException e){
e.printStackTrace();
}

response.sendRedirect(“html/manterMedidor/Teste.jsp”);

}

O SEGUINTE ERRO É DISPARADO

POR FAVOR ALGUEM SABE COMO RESOLVER É PODE ME AJUDAR

#2

pelo erro, ele nao encontra o arquivo teste.jasper…

#3

COMO EU FAÇO PARA QUE O JASPER POSSA SER LIDO ESTOU USANDO O TOMCAT.
A MINHA ESTRUTURA ESTA ASSIM .
WEBAPPS\MEDIDORES\WEB-INF\CLASSES\BEAN\RELATORIOS

#4

COMO EU FAÇO PARA QUE O JASPER POSSA SER RECONHECIDO, EU ESTOU USANDO O TOMCAT E MINHA ESTRUTURA ESTA ASSIM
C:\Program Files\tomcat\webapps\medidores\WEB-INF\classes\Bean\Relatorios

#5

Eu uso o Struts e na Action que gera o reletório eu acesso o contexto e pego o path à partir daí coloco somente a package onde está o .jasper sacow?

Algo como:

mapping.getServletContext().getRealPath();

Acho que é isso, e me retorna o caminho absoluto do diretório base da minha aplicação :wink:

Flw

#6

Estou usando assim
String str = this.getClass().getResource(“Bean/Relatorios/teste.jasper”).getFile();
que da mesma forma me retorna o caminho absoluto
mas continua dando o mesmo erro

#8

eu usei
