iText 5 Add a text field under a paragraph - itext

Question

I'm using iText to create a PDF in my java spring mvc web project. I'm new to iText 5. Could anyone tell me how to add a text field under a paragraph? Based on my current code, the text field is not displayed under the paragraph. I may add more questions to the PDF so I want to display each text field under the paragraph.
try {
List<FormQuestionBean> questions = formBuilderBean.getQuestions();
MyHeaderAndFooter event = new MyHeaderAndFooter();
Document pdfDocument = new Document(PageSize.A4);
pdfDocument.setMargins(20, 20, 20, 30);
ByteArrayOutputStream pdfBaos = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(pdfDocument, pdfBaos);
writer.setPageEvent(event);
pdfDocument.open();
Paragraph paragraph1 = new Paragraph(FORM_NAME + " : " + formBuilderBean.getName(), HEADING);
paragraph1.setSpacingAfter(20);
pdfDocument.add(paragraph1);
for (FormQuestionBean formQuestionBean: questions) {
if (formQuestionBean.getFieldImplementation().contentEquals("Text Field")) {
Paragraph p = new Paragraph(formQuestionBean.getName());
pdfDocument.add(p);
TextField text = new TextField(writer, new Rectangle(36, 788, 559, 806), "text" );
text.setBackgroundColor(BaseColor.WHITE);
PdfFormField field = text.getTextField();
writer.addAnnotation(field);
}
}
pdfDocument.close();
response.reset();
response.setHeader("Content-Length", String.valueOf(pdfBaos.size()));
response.setContentType("application/pdf");
response.setContentLength(pdfBaos.size());
String downloadName = getFormFileName(".pdf");
response.setHeader("Content-Disposition", "attachment; filename=\"" + downloadName + "\"");
OutputStream outputStream = response.getOutputStream();
pdfBaos.writeTo(outputStream);
outputStream.flush();
outputStream.close();
return true;
} catch (Exception e) {
logger.error(e);
e.printStackTrace();
return false;
}

Answer 1

I figured out using table and cell. Below is the code:
try {
List<FormQuestionBean> questions = formBuilderBean.getQuestions();
MyHeaderAndFooter event = new MyHeaderAndFooter();
Document pdfDocument = new Document(PageSize.A4);
pdfDocument.setMargins(20, 20, 20, 30);
ByteArrayOutputStream pdfBaos = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(pdfDocument, pdfBaos);
writer.setPageEvent(event);
pdfDocument.open();
Paragraph paragraph1 = new Paragraph(FORM_NAME + " : " + formBuilderBean.getName(), HEADING);
paragraph1.setSpacingAfter(20);
pdfDocument.add(paragraph1);
for (FormQuestionBean formQuestionBean: questions) {
if (formQuestionBean.getFieldImplementation().contentEquals("Text Field")) {
PdfPTable table = new PdfPTable(1);
table.getDefaultCell().setBorder(Rectangle.NO_BORDER);
PdfPCell c1 = new PdfPCell(new Phrase(formQuestionBean.getName()));
c1.setFixedHeight(30);
table.addCell(c1);
PdfPCell c2 = new PdfPCell();
TextField text = new TextField(writer, c2, "text" );
text.setBackgroundColor(BaseColor.WHITE);
FieldPositioningEvents events = new FieldPositioningEvents(writer, text.getTextField());
c2.setCellEvent(events);
c2.setFixedHeight(30);
table.addCell(c2);
pdfDocument.add(table);
}
}
pdfDocument.close();
response.reset();
response.setHeader("Content-Length", String.valueOf(pdfBaos.size()));
response.setContentType("application/pdf");
response.setContentLength(pdfBaos.size());
String downloadName = getFormFileName(".pdf");
response.setHeader("Content-Disposition", "attachment; filename=\"" + downloadName + "\"");
OutputStream outputStream = response.getOutputStream();
pdfBaos.writeTo(outputStream);
outputStream.flush();
outputStream.close();
return true;
} catch (Exception e) {
logger.error(e);
e.printStackTrace();
return false;
}
