Prezados, estou tendo dificuldades em chamar um relatório desenvolvido no iReport.
Estou utilizando o seguinte codigo em meu servlet:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
ServletOutputStream sOutputStream = response.getOutputStream();
String caminho = "relatorios/";
String relatorio = caminho + "rel.jasper";
java.net.URL resource = this.getClass().getClassLoader().getResource(relatorio);
InputStream reportStream = new FileInputStream(resource.getFile());
try {
HashMap<String, String> parametros = new HashMap<String, String>();
parametros.put("nome", "Joaquim");
JasperRunManager.runReportToPdfStream(reportStream, sOutputStream, parametros);
response.setContentType("application/pdf");
sOutputStream.flush();
sOutputStream.close();
} catch (JRException e){
StringWriter sWriter = new StringWriter();
PrintWriter pWriter = new PrintWriter(sWriter);
e.printStackTrace(pWriter);
response.setContentType("text/plain");
response.getOutputStream().print(sWriter.toString());
}Contudo, ocorre um erro ao executar o relatório.
O que pode estar ocorrendo?
Segue o erro:
