If you want to share a composite component between projects you should package it in a JAR.
But how would you do it? Well it is pretty easy. First include the resources in the META-INF/resources directory. E.g.
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:cc="http://java.sun.com/jsf/composite">
<body>
<cc:interface></cc:interface>
<cc:implementation>
This is coming from a JAR-packaged composite component! Hurray :)
</cc:implementation>
</body>
</html>
And then add a faces-config.xml in the META-INF directory. E.g.
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.1"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd">
</faces-config>
And then JAR it all up.
