I generated those files with an owner password and user password
"null" and i doubt
if it will let me open it.

Urgh. I don't think so. iText's crypto support boils
down to:
"Did you open it with the OWNER password? No? Then we
won't touch it!"
That may only be for stamper though... lemme check.
According to my interpretation of the code, as long as you're sticking
to PdfReader, you're fine. It's PdfStamper that throws when you don't
use the owner password (and presumably Pdf*Copy*, but I didn't check
them).
So you're fine. I think.

Will this solution work if my document is
encrypted but not password protected, ie
if my documents are immutable and not password
protected can i still load their field
value pairs?
Thanks for you quick reply

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?
