Email | Java | Validate

Another solution recommends using a text match pattern.
This works, but as long as you've got mail.jar in your classpath anyway, you might as well use this technique instead. (Plus, I think it works with older JDK 1.2+, whereas pattern.compile is 1.4+)

Note that it also accepts a comma-separated list of emails, just like a To: or CC: address line would.

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

public void onValidate(String value) throws InvalidEmail {

    try {

        InternetAddress.parse(value);

    } catch (AddressException e) {

        throw new InvalidEmail("Email: "+value+" is invalid.  Try something like myname@myhost.com");

    }

}
