Struts2 Field Validator in XML - regex issue

Hello,

I am using the xml validation for an action in my struts2 application. The issue I'm experiencing is related to a regex validator that I've listed below. Basically, I'm trying to prevent anyone from entering a caret (^) in my course name field.

The following inputs work with this regex:
^a
^asdfds
b^
D^dfda

However, if someone enters just a caret for the course name, the regex fails. It does not find the caret for some reason. I've test the following two regex with this same result, so I'm guessing it is struts2/java related rather than my regex.

regex 1: ([\^])
regex 2: \^

All other validation is working correctly, it's just this regex that is causing me problems. Anyone know what I'm doing wrong?

Ok, I just tried the following regex and it also fails, but it works when I try it using online validators as do the previously posted regex.

^.*([\^])+.*$
