Managing Validators

This feature is supported in the Ultimate edition only.

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.

    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.

To define the validations to apply to a form

  1. Open validation.xml.
  2. To add a validation definition, add the <form-validation> tag manually.
  3. Switch to the Struts Assistant tool window, tab Validator. A new node appears in the Structure Tree.
  4. Edit the attributes of the validation definition in the Properties Table.
