If you just want to compare form field values, that's not particularly
hard. You should be able to simply load all the field name/value pairs
into maps and .equals() them. Something like:
public bool formsEqual(PdfReader reader1, PdfReader reader1) {
AcroFields fields1 = reader1.getFields();
AcroFields fields2 = reader2.getFields();
Map<String, String> fieldMap1 = new HashMap<String, String>();
Map<String, String> fieldMap2 = new HashMap<String, String>();
Set<String> fieldNames = fields1.getFields().keySet();
// if the number of fields differ, they're not equal.
if (fieldNames.size() != fields2.getFields().size()) {
return false;
}
for (String name : fieldNames) {
fieldMap1.put(name, fields1.getField(name));
fieldMap2.put(name, fields2.getField(name));
}
// if the field values differ, they're not equal
return fieldMap1.equals(fieldMap2);
}
Is that what you had in mind? You could spruce that up with logging...
say within the for loop you could dump the field name and both values to
Standard Out every time the two field values differ.

Subject: Re: [iText-questions] comparing pdf files
I am trying to compare the data written to these pdf files.
I am writing some data to a pdf file and i want to compare the
data written to the fields in the pdf file if they are correct.
For example, the date, name, address etc

Not really, no. Two files that are visually identical
can be radically different under the hood, and two files that are nearly
identical byte-wise can be quite different visually.
What about the files are you trying to compare?
