Question: Where do I get "validator_rules.xml" file?

From the Struts documentation:

By convention, the validators your application uses can be loaded through a file named "validator-rules.xml", and the validator forms (or "validations") can be configured separately (say, in a "validations.xml" file).

You get validator-rules.xml (not validator_rules.xml) from the Struts installation. Look inside searching for the proper name (with - not _).

The "src" archive is sure to contain it.
