I am creating a PDF document wth the following code:
public void encodeBegin(FacesContext contexto){
log.debug("Generando PDF");
this.setDataTableFields();
Font font8 = FontFactory.getFont(FontFactory.HELVETICA, 32);
ResponseWriter out = contexto.getResponseWriter();
Document document = new Document(PageSize.LETTER,36, 72, 108, 180);
ByteArrayOutputStream output = new ByteArrayOutputStream();
try{
PdfWriter writer = PdfWriter.getInstance(document, output);
writer.setFooter(new HeaderFooter(new Paragraph("Suprema Corte de
Justicia de La Nación"),true));
document.addAuthor("Suprema Corte de justicia de la Nación");
document.addCreationDate();
document.open();
document.add(new Paragraph(new Phrase("Resultado de la Búsqueda",
font8)));
this.setTable(new PdfPTable(this.getFieldsArray().length));
this.getTable().getDefaultCell().setBorder(0);
this.getTable().getDefaultCell().setHorizontalAlignment(PdfPCell.ALIGN_JUSTIFIED);
this.printHeaders(this.getTable());
this.printRows(this.getTable());
document.add(this.getTable());
document.close();
out.write(output.toString());
out.flush();
}catch(Exception e){
log.debug("Error generando la tabla, método encodeBegin del PDF:");
e.printStackTrace();
}
}
/**
* Prints the headers.
* @param out The place where the headers will be render
*/
protected void printHeaders(PdfPTable out){
int largo = this.getColumnHeadersArray().length;
int headerActual;
String th;
Font font8 = FontFactory.getFont(FontFactory.HELVETICA, 8);
try{
if (this.getShowRowNumber()){
th = "";
out.addCell(new Phrase(th + this.getRowNumberLabel(), font8));
}
for (headerActual = 0; headerActual < largo; headerActual++){
out.addCell(new
Phrase(this.getColumnHeadersArray()[headerActual], font8));
log.debug("Header:
"+this.getColumnHeadersArray()[headerActual]);
}
}catch(Exception e){
log.debug("Error generando la tabla, método printHeaders:");
e.printStackTrace();
}
}
/**
* Prints the rows.
* @param out The place where the rowswill be render
*/
protected void printRows(PdfPTable out){
String [][] contenido =this.getContents();
int largo = contenido.length;
int ancho = contenido[0].length;
int rowActual;
int colActual;
Font font8 = FontFactory.getFont(FontFactory.HELVETICA, 8);
try{
for (rowActual = 0; rowActual<largo;rowActual ++){
for (colActual = 0; colActual < ancho; colActual++){
if (contenido[rowActual][colActual]!=null){
out.addCell(new
Phrase(contenido[rowActual][colActual], font8));
}else{
out.addCell(new Phrase("", font8));
}
log.debug("contenido: "+contenido[rowActual][colActual]);
}
}
}catch(Exception e){
log.debug("Error generando la tabla, método printRows:");
e.printStackTrace();
}
}
This code is for a Custom Tag Lib with JSF i had a table with more than 2000
rows but nothing is shown up...
the result of this is a 714 pages document with blank pages...
am i missing something?
Greetings.
