That regex seems to have repeated elements. If you work out what the repeating element in square brackets means, you are a long way towards solving the whole problem.

I have learned the basics of regular expression. Thanks to all. I got one problem with my regex.
My regex is written in such a way that it should not allow alpha numeric, and special characters. Thats fine, but its failing in one scenario for targetPage and that is Prestige$%$lll.jsp. How to make sure that it should work.
I am getting the following error:

Fairly obviously, by making sure that it 'understands' the "%nn" syntax.
My suggestion: write a little program that does this using ONLY standard String methods, and then translate it to a regex. You may find that your program is actually faster than a regex; and for something complicated like this, it's highly likely to be more readable too.
Isn't it funny how there's always time and money enough to do it WRONG?
