To enable the struts validator on an application, which configuration setting should be applied in...

To enable the Struts validator, you typically need to set the validate attribute to “true” in the Struts configuration file. This is done within the  section of the struts-config.xml file, where you define your form beans and their associated validation rules. Here’s a step-by-step explanation:

Open the struts-config.xml file.

Locate the  section.

For each form bean that requires validation, ensure that the validate attribute is set to “true”.

Define your validation rules in a separate XML file, typically named Validation.xml.

Link this validation file with your form bean using the  tags.

Ensure that the  plug-in is defined in your struts-config.xml file to enable the validation framework.

References: While I can’t provide direct references to the EC-Council’s CASE JAVA courses and study guides, you can refer to the official Struts documentation and community resources for more information on configuring the validator in Struts applications. The official Apache Struts website would be a good starting point.
