Solution Elements
• Your custom validator should extend com.ptc.core.ui.validation.DefaultURLValidator
• You can override an existing out-of-the-box validator with your own custom validator. To do this, register your validator for the URL in WT_HOME/codebase/config/urlValidators/custom-validators.xml
• Override public UIValidationStatuspreValidateAction (UIValidationKey validationKey, UIValidationCriteria validationCriteria) method.
• UIValidationStatus.PERMITTED means that the URL is accessible and all other statuses means the URL is not accessible
• Note that the URL Validation service will not execute other available methods in DefaultURLValidator.
Possible attributes of urlvalidator elements are listed in the following table.
