JavaServer Faces TagLibs

If you want to use JSF with your webapp, you should copy the relevant jars from your implementation of choice into your $JETTY_BASE directory, ideally into $JETTY_BASE/lib/ext. If that directory does not exist, enable the ext module, which will create the directory and ensure all jars within it are put onto the container classpath.

Then you will need to tell Jetty which of those jars contains the *.tld files. To accomplish that, you need to specify either the name of the file or a pattern that matches the name/s of the file/s as the org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern context attribute. You will need to preserve the existing value of the attribute, and add in your extra pattern.

Here’s an example of using a context xml file to add in a pattern to match files starting with jsf-, which contain the *.tld files:

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "https://jetty.org/configure_10_0.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext"> (1)
    <Call name="setAttribute"> (2)
      <Arg>org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern</Arg> (3)
      <Arg>.*/jetty-servlet-api-[^/]*\.jar$|.*/javax.servlet.jsp.jstl-.*\.jar$|.*/org.apache.taglibs.taglibs-standard-impl-.*\.jar$|.*/jsf-[^/]*\.jar$</Arg> (4)
    </Call>
</Configure>

1	Configures a `WebAppContext`, which is the Jetty component that represents a standard Servlet web application.
2	Specifies a context attribute.
3	Specifies the name of the context attribute.
4	Adds the additional pattern `./jsf-[^/]\.jar$` to those already existing.
