  1. Select faces-config.xml in the Project Explorer of the J2EE perspective.

    The JSF Application Configuration editor opens.

  2. Select the Component tab of the editor.

  3. Expand the Validators section.

    A list of defined validators displays.

  4. Click Add.

    A new validator is added to the Converters list with the default name New Validator x .

  5. (Optional) Change the default validator name to a unique, descriptive name in the Display name field of the General section.

  6. (Optional) Type a description in the Description field.

  7. Type an ID in the Validator ID field.

  8. Click Browse and select a Validator Class.
