Note that there is only limited support for
forms created with Designer. You also need
a very recent version of iText.
However, that's not a problem.
Let's get some source code from the book ;-)
// create a reader object
PdfReader reader = new PdfReader("temp.pdf");
// create a stamper object
PdfStamper stamper =
new PdfStamper(reader, new FileOutputStream( "result.pdf"));
// get the form from stamper (because we are going to fill out fields)
AcroFields form = stamper.getAcroFields();
// first let's see what fields are inside:
HashMap fields = form.getFields();
for (Iterator i = fields.keySet().iterator(); i.hasNext();) {
System.out.print(i.next());
}
// iText has found two fields:
// form1[0].Page1[0].name[0]
// form1[0].Page1[0].lastname[0]
// now let's fill those fields:
form.setField("form1[0].Page1[0].name[0]", "Doe");
form.setField("form1[0].Page1[0].lastname[0]", "John");
// the next line removes the form
stamper.setFormFlattening(true);
stamper.close();
// and we're done!
FYI: you are talking about AcroFields, but you do have
an XFA form in your PDF. This can be checked like this:
XfaForm xfa = form.getXfa();
System.err.println(xfa.isXfaPresent());

OK, the above example solves half of the problem: we have
added a first and last name (you may want to use setExtraMargin()
because I see that your fields aren't positioned very well; or
you could redesign your form).
Now you want to add subjects and grades to the document.
I suggest that you use PdfPTable (maybe wrapped in a
ColumnText object if you expect that the table will not
fit on one page).
Unfortunately iText doesn't know where it should add the table.
Either you have to take a ruler, measure the paper and calculate the
coordinates where iText can write the table (with writeSelectedRows)
or column (setSimpleColumn).
Or you redesign your form and add an extra field (for instance a
button) that marks the area where iText should draw the table.
You can then get the coordinates with getFieldPositions and
use these coordinates to draw the table or column.
