Managing Validators

The Validator functionality within the Struts framework is intended for validating the data of forms in a Web application.

The Validator functionality uses two xml configuration files:

• The validator-rules.xml file defines the standard reusable validation routines that make the basis for configuring form-specific validations. The file is created when you enable Struts support and is supplied with a predefined set of commonly used validation rules such as Required, Minimum Length, Maximum length, Date Validation, Email Address validation and others.

  Note

  The file is closed for editing.

• In the validation.xml file, define the validations applied to a particular form bean.

While you edit validation.xml, IntelliJ IDEA coordinates the code of the two files and provides you with coding assistance based on the routines defined in validator-rules.xml.
