Hi Matthias, I believe that the ^ and $ in a regular expression pattern are used to symbolize the start and end of the evaluated string. Thus:
^a means the string must begin with an a, a$ means the string must end with an a. Struts may handle regex differently, but if you remove them, it will only change the pattern which is matched. I could be wrong about this, but I'll give it a go: ^[a-zA-Z]*$ - requires a string of zero or greater length that starts with, ends with, and contains only a-z and A-Z (that is if there are characters)) [a-zA-Z]* - basically says that if the string length > 0, it must have a-z or A-Z somewhere in it.
