PatternSyntaxException unbalanced parenthesis

[selvaKumar esra]

Hi, i am new to the play framework, downloaded the latest version play-2.2.0-M2

navigated to samples to get a hang of play!. 

tried http://localhost:9000/

unfortunately, i got following exception in server log, Understand the exception sounds like regex pattern failure. However unable to trace back to root cause with the exception. 

please advise.

Cheers

That stack trace doesn't come from Play 2, it comes from Play 1.  You might want to double check which version of Play you're running.

The play -version is the problem. i downloaded 2.2 but had 1.2 still in my path which causes this error.
