How to include external Javascript file in a JSF page

Question

I want to include the URL of jQuery UI http://code.jquery.com/ui/1.9.0/jquery-ui.js in my JSF page. I saw many questions which said <h:outputScript> should be used, but in none of the answers I saw an example as to how to include an URL. The answers were only relevant if the js file is present in some folder of the project.

Can someone please help where I have to include it in my page?

Answer 1

Just use plain HTML <script> element the usual way.

<script src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script>

The <h:outputScript> can only refer local scripts. You'll only miss its dynamic versioning, modularity and relocation advantages, but that should technically not harm for a static and external script.

It's however possible to use a custom ResourceHandler to change the URL of a <h:outputScript> to be an external URL for pure CDN purposes. OmniFaces CDNResourceHandler is such an example.

Unrelated to the concrete problem, PrimeFaces components are built around jQuery/UI. Are you absolutely positive that you need a separate instance of jQuery UI library?
