Olá a todos, estou com uma grande dor de cabeça com o Ireport, gostaria de uma ajuda se possível.
Seguinte tenho um relatório principal com 3 colunas de subreport e um subreport que vai sendo mostrado conforme a necessidade.
protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html; charset=iso-8859-1");
response.setCharacterEncoding("iso-8859-1");
ServletContext sc = getServletContext();
byte[] bytes = null;
ArrayList listaLicenc = new ArrayList();
try {
ArrayList<Etiq> lista = new ArrayList();
lista.add(new Etiq("Etiqueta de equipamento", "Modelo: ----- Serial: XXXXXXX", "Licença: XXXXXXXXXXXXXXXXXXXXXXXXX"));
// Populando objetos para o relatorio
RelatorioLicencas jrds = new RelatorioLicencas(lista);
// Parametros do relatorio
HashMap parameters = new HashMap();
parameters.put("SUBREPORT_DIR", sc.getRealPath("/Relatorio/"));
// Lendo arquivo jasper
File reportFile = new File(sc.getRealPath("/Relatorio/relatorioLicencas.jasper"));
// Manuseando os dados para o relatorio
bytes = JasperRunManager.runReportToPdf(reportFile.toURL().openStream(), parameters, jrds);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (bytes != null) {
if (bytes.length > 0) {
try {
response.setContentType("application/pdf");
response.setContentLength(bytes.length);
response.getOutputStream().write(bytes, 0, bytes.length);
response.getOutputStream().flush();
response.getOutputStream().close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
}
}
class RelatorioLicencas implements JRDataSource {
private List listaLic1 = new ArrayList();
private List listaLic2 = new ArrayList();
private List listaLic3 = new ArrayList();
private boolean pag;
private int coluna = 1;
public RelatorioLicencas(ArrayList parEtiquetas) throws Exception {
for (int i = 0; i < parEtiquetas.size(); i++) {
Etiq e = (Etiq) parEtiquetas.get(i);
switch (coluna) {
case 1:
this.listaLic1.add(e);
break;
case 2:
this.listaLic2.add(e);
break;
case 3:
this.listaLic3.add(e);
break;
}
coluna++;
if ((i + 1) % 3 == 0) {
coluna = 1;
}
}
}
@Override
public boolean next() throws JRException {
if (pag == false) {
pag = true;
return true;
}
return false;
}
@Override
public Object getFieldValue(JRField args) throws JRException {
if (args.getName().equalsIgnoreCase("listaLic1")) {
return new JRBeanCollectionDataSource(listaLic1);
}
if (args.getName().equalsIgnoreCase("listaLic2")) {
return new JRBeanCollectionDataSource(listaLic2);
}
if (args.getName().equalsIgnoreCase("listaLic3")) {
return new JRBeanCollectionDataSource(listaLic3);
}
return null;
}
}
public class Etiq implements Serializable {
private String titulo = "";
private String descricao = "";
private String licenca = "";
private boolean flag = false;
// Constructor, sets and gets .....
}Me retorna o seguinte erro:
