Please use XDA's search feature before making threads. This is covered, numerous time throughout the L9 forums.
To answer -
Short, yes. Long, you cannot flash a custom recovery to a device with a locked bootloader.
There is a 2nd-init CWM that can be installed on devices with a locked bootloader. It must be installed with the L9RecoveryInstaller_1.5.0.apk. Search and you'll find it. If you decide to try unlocking your bootloader I wish you the best of luck. Many of us have failed miserably.
