is there any Java validator libraries i can use to validate text input from an android app?

i know that in spring there are validators for various different types such as checking if a value is a int, if a value is a valid email, etc etc.

Anything similar in core java or even android?

cheers in advance. i dont want to re-invent the wheel if its already been implemented. i could always sue java reg expressions to construct my own ones but was wondering if their was one done specifically for email formats.

    Here is the link to my blog containing the sources and a small bit of explaining Form validation on Android: link text
