Environment Details

GlassFish Version (and build number): 7.0.9
JDK version: 17
OS: Windows 11 Pro
Database: MySQL
IDE: Netbeans 19

Problem Description

I am migrating my project from Glassfish 4 to Glassfish 7. I got an exception when I run the project on Netbean 19 with Glassfish 7.0.9 server. I can run the same project on Netbeans 8.2 with Glassfish 4 successfully.

The problem is easily reproducible.

Stack traces or command outputs

Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: java.util.concurrent.ExecutionException: com.sun.faces.config.ConfigurationException: Unable to parse document 'file:/C:/Users/allen/Documents/projects/emlucy/TagLib/TagLib/target/TagLib-1.0/WEB-INF/mytagLab.xml': Cannot invoke "com.sun.faces.config.manager.FacesSchema.loadSchema()" because "schemaId" is null|#]

Steps to reproduce

Create a new Maven web application on Netbeans 19.
Edit web.xml and pom.xml as shown below.
Create /WEB-INF/mytagLab.xml and /tags/sample_tag.xhtml as shown below.

Sample code/application

Here is the content of the web.xml.

Impact of Issue

I could not continue on migrating without fixing this problem.

The root tag of your taglib file (<facelet-taglib>) should have a schema. In your case it's completely empty.

For the current version in GlassFish 7 (Faces 4):

<facelet-taglib id="someId"
    xmlns="https://jakarta.ee/xml/ns/jakartaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/web-facelettaglibrary_4_0.xsd"
    version="4.0"
>

See e.g. https://github.com/omnifaces/showcase/blob/master/src/main/webapp/WEB-INF/showcase.taglib.xml

Thank you. The exception went away.

Here is the XHTML page I am referring the tag with 't'. However, the system can't find the namespace "http://mycompany.com/tags" when I try to call my tag "sample_tag" in my pages. What am I missing?

Here is my sample page.

<?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:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:t="http://mycompany.com/tags" >

<h:body>
    <ui:composition >
        <t:simple_tag label="My Label" value="My Value" />
    </ui:composition>
</h:body>
