You just need:
ColumnText ct = new ColumnText(null);
ct.setSimpleColumn(LEFT_MESSAGE_LOWER_X, LEFT_MESSAGE_LOWER_Y,
LEFT_MESSAGE_UPPER_X,
LEFT_MESSAGE_UPPER_Y, MESSAGE_PADDING, MESSAGE_ALIGNMENT);
ct.addText(new Phrase(“Text to enter”,FONT));
if (ColumnText.NO_MORE_TEXT !=ct.go(true)) {
“TOO MUCH TEXT”

> After they enter their text and hit submit the a pdf file is created and
> it

> We would like to provide some real time validation using ajax. After each
