It's not JDOM, it's Java. Java requires you to escape a \ in a string as \\.

Ankit,
What you describe is what I would expect but it seems that in practice
I have to double escape the pattern. I am running my validation via
JDOM, so it is possible that is inserting the double escaping
requirement. What I have is a pattern that looks like
"[0-9]{18}[\\.\\,][0-9]{3}", which seems to work fine. However "[0-9]{18}[\.\,][0-9]{3}" does not. Since you believe that it should
work, I will see what happens if I remove JDOM from the picture.
Thanks,
David Morris

In order to match dot(.) or comma (,) the expression [\.,] is enough. There is no reason to escape the comma itself or to put comma as an indicator of OR in the regex. The valid escapes are given in [1].
