Including a JavaScript library in a Maven project with JSF

Currently, I am working on a JSF project with Maven and I am utilizing a JavaScript library for developing a 3D graphics interface. I am looking for a way to add/import this JS library into my project without the need to manually move/copy all the JS files into the webapp/resources directory. I have attempted to do so using the tags <resource> and <dependency> within the <dependencies> tag of the pom.xml file, but unfortunately, it did not yield the desired results.

The specific error I am encountering is related to the following line of code:

<h:outputScript name="Three.js" />

It appears to be indicating that the specified resource cannot be located.

Any guidance or suggestions on how to resolve this issue would be greatly appreciated.

Additional information: I am working with JSF 2.1.

When it comes to managing Java dependencies and building applications, Maven is a powerful tool that is widely used. Typically, Maven is utilized to create Java applications. While JavaScript is commonly run on the client side of a web application, Java is executed on the server side. However, there are instances where Maven can integrate JS resources into a Java library, with PrimeFaces being a notable example.

When it comes to handling resources, including JS scripts, in a JSF application, there are essentially two approaches:

  1. One method is to import external scripts using a standard HTML <script> tag. By employing this technique, there is no need for specific imports, as external JSF scripts can be easily referenced.
  2. Alternatively, internal scripts can be imported using the <h:outputScript> tag. This allows resources, such as scripts, to be imported from within the web application, often from the designated resources folder. Additionally, scripts can be accessed from Maven imported artifacts, like PrimeFaces, that contain JS resources. In such cases, specifying the library attribute of <h:outputScript> is necessary.

It is worth mentioning that Three.js is not typically included in Java libraries. Therefore, the recommended approach is to either refer to an external script or import it within the JSF project. However, if the Three.js library is indeed available via Maven, importing it would allow you to reference it in your views.
