webjar
Available since Struts 7.3.0.
Please make sure you have read the Tag Syntax document and understand how tag attribute syntax works.
Description
Resolves a version-less WebJar resource path to a servable URL and writes it to the output
(or stores it in a variable when var is set). For example, bootstrap/css/bootstrap.min.css is resolved to
<ctx>/static/webjars/bootstrap/5.3.8/css/bootstrap.min.css, so you never hardcode the WebJar version in your templates.
The tag emits a plain URL string, so it composes with script, link, or a raw <link> /
<script> element. See Static Content for the serving pipeline and
configuration constants.
