It is contained in struts-core.jar, and should be referenced in the struts-config.xml under the plug-in element for the ValidatorPlugIn. <plug-in className="org.apache.struts.validator.ValidatorPlugIn"> <set-property property="pathnames" value="/org/apache/struts/validator/validator-rules.xml, /WEB-INF/validation.xml"/> </plug-in> These are the default error messages associated with each validator defined in this file. They should be added to your projects ApplicationResources.properties file or you can associate new ones by modifying the pluggable validators msg attributes in this file. # Struts Validator Error Messages errors.required={0} is required. errors.minlength={0} can not be less than {1} characters. errors.maxlength={0} can not be greater than {1} characters. errors.invalid={0} is invalid. errors.byte={0} must be a byte. errors.short={0} must be a short. errors.integer={0} must be an integer. errors.long={0} must be a long. errors.float={0} must be a float. errors.double={0} must be a double. errors.date={0} is not a date. errors.range={0} is not in the range {1} through {2}. errors.creditcard={0} is an invalid credit card number. errors.email={0} is an invalid e-mail address. Note: Starting in Struts 1.2.0 the default javascript definitions have been consolidated to commons-validator. The default can be overridden by supplying a <javascript> element with a CDATA section, just as in struts 1.1.--><form-validation> <global> <validator name="required"
