How to prevent values over 99inches but still allow 13.5 inches

I am tasked with preventing someone from entering in 120 into the following three inputText boxes.
But they still have to be able to enter i.e. 13.5 inches.

How would I go about doing this? I do not even know where to start.

I'm not quite sure what you're asking here. If you prevent values over 99 inches, why is 13.5 inches a special case worth mentioning? Is that you really mean than only values between 0 and 99.9 or so are allowed?

If so, a converter isn't what you need. You need a RangeValidator. Basic JSF stuff.

If you're ambitious, you can also attach JavaScript to the controls to limit things on the client side, but even then I'd recommend putting range validation on your input controls.
