I'm using Jakarta EE 9, Glassfish 6.0, and JSF 3.0 and getting "Target Unreachable, identifier '' resolved to null..." I know questions like this have been asked before but I tried all proposed solutions. Also, I could find very few discussions about version 3.0 of JSF. I would appreciate it if someone could help me spot what wrong is.

It is because of Application Server that cannot fully support to JSF-3.0. I've got same error when I tested jakartaee-tutorial-examples/web/jsf/guessnumber-jsf project. I've tried guessnumber-jsf.war file on WildFly 24.0.0.Final and wildfly-23.0.2.Final Application servers. I got same error on both servers. But when I tested on Wildfly-preview-23.0.2.Final which supports JakartaEE 9.1 and JDK 11, it is working well.

I'm trying to use Bean validation instead of JSF validation since it is a more DRY aproach, i'm using the annotations on my model but when i insert null data on jsf fields it does nothing...
None of the annotations that i'm using is having any effect, its like they are not there....

ref: Bean Validation #NotNull, #NotBlank and #NotEmpty does not work in JSF+Tomcat
I'm trying to create a questionnaire website using GlassFish, JSF/Primefaces and for database, I'm using the embedded derby DB of Glassfish.
I followed this video tutorial (http://www.youtube.com/watch?v=aBjlR9HoR50) which is really good but I haven't managed to get my project to work properly.
My project deploys successfully on Glassfish but when I see the webpage on the browser, it is obvious that the backing bean is not called from the xhtml page.
Here is the backing bean code:
package ac.hw.questionnaire;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Set;
import java.util.logging.Logger;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
import javax.inject.Named;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;
import javax.persistence.metamodel.EntityType;
import javax.persistence.metamodel.Metamodel;
import ac.hw.questionnaire.model.Question;
/**
* Session Bean implementation class QuestionsEJB
*/
#Stateless
#LocalBean
#Named
public class QuestionsEJB {
private Logger logging = Logger.getLogger(this.getClass().getName());
#PersistenceContext (unitName="QuestionnaireEmbeddedDB")
EntityManager em;
private List<Question> questions;
private String name;
/**
* Default constructor.
*/
private EntityManager getEntityManager() {
if (em==null){
logging.info("EntityManager is null!");
EntityManagerFactory emf = Persistence.createEntityManagerFactory("QuestionnaireEmbeddedDB");
em = emf.createEntityManager();
if (em==null){
logging.info("EntityManager is STILL null!");
}
}
return em;
}
public QuestionsEJB() {
// TODO Auto-generated constructor stub
logging.info("Logger: Constructor of QuestionsEJB called");
if (getEntityManager()==null){
return;
}
List resultList = em.createQuery("select q from Question q").getResultList();
if (resultList==null){
logging.info("ResultList is null");
}else{
logging.info("Constructor/Retrieved "+resultList.size()+" questions");
}
}
public List<Question> getQuestions() {
System.out.println("getQuestions method called");
if (questions==null){
this.questions = em.createQuery("select q from questions q").getResultList();
System.out.println("Retrieved "+questions.size()+" questions");
}
return questions;
}
public String getMyText(){
return "myTextFromEJB";
}
public void setQuestions(List<Question> questions) {
this.questions = questions;
}
public String getName() {
this.logging.info("Get name!");
return name;
}
public void setName(String name) {
this.logging.info("Set name!");
this.name = name;
}
}
Here is my xhtml page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<h:panelGrid columns="4" cellpadding="5">

<p:dataTable var="qVar" value="#{QuestionsEJB.questions}">
<h:column>#{qVar.questionText}</h:column>
</p:dataTable>
</ui:define>
</ui:composition>
</html>
When I visit the xhtml page on the browser, none of the values are displayed and the Submit button doesn't do anything which tells me that the facelet doesn't bind to the EJB.
My web.xml (inside WebContent/WEB-INF/) has the following content:
<web-app version="3.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
</web-app>
My beans.xml file (also inside WebContent/WEB-INF) is empty (nothing at all).
My glassfish-web.xml file (also inside WebContent/WEB-INF) has the following content:
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app>
<context-root>/QuestionnaireEmbeddedDB</context-root>
<parameter-encoding default-charset="UTF-8"/>
</glassfish-web-app>
I have no exceptions on the server.log and the only unorthodox thing is that the EntityManager is null until I explicitly call the getEntityManager() method on the QuestionEJB.
Why can't I get the xhtml to connect to the backing bean?
Also, the template.xhtml has the following content:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

I am using JSF 2.2.4 on GlassFish 3.1.2.2.
I have this backing bean:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import java.io.Serializable;
#ManagedBean(name="testMB")
#RequestScoped
public class TestMB implements Serializable {
public long id;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
}
And this view test.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<f:metadata>
<f:viewParam name="id" value="#{testMB.id}"/>
</f:metadata>
<h:body>
<h:inputText value="#{testMB.id}" />
</h:body>
</html>
When I open /test.html?id=123, then the ID shows up as 0 instead of 123. Why didn't <f:viewParam> do its job?
Updated
I installed GlassFish 4.0.
Maven dependencies for JSF:
<dependency>
<groupId>javax.faces</groupId>
<artifactId>javax.faces-api</artifactId>
<version>2.2</version>
</dependency>
faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>

<!-- JSF and Spring are integrated -->
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>

</faces-config>
And test.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html">

<f:viewParam name="id" value="#{testMB.id}"/>
</f:metadata>
<h:body>
<h:inputText value="#{testMB.id}" />
</h:body>
</html>
But the ID shows up as 0.

Problem solved
Pages named as *.xhtml.
In web.xml was:

<url-pattern>*.html</url-pattern>
</servlet-mapping>
Right:
<url-pattern>*.xhtml</url-pattern>

what is the problem ? do i not clearly state the upload class ?
Any help is good :)
You have overridden the #ManagedBean by a <managed-bean> declaration on the faces-config.xml, however that <managed-bean> declaration has a different managed bean name, namely bean instead of upload.
You have basically 3 options:
Use #{bean} instead of #{upload} in your view.
Rename the <managed-bean-name> in faces-config.xml from bean to upload so that you can use #{upload} in your view.
Get rid of <managed-bean> altogether so that the #ManagedBean will be used. The managed bean name defaults to the bean class name with 1st char lowercased, thus #{upload} should work.
For the remaining, you are not consistent with Java naming conventions. Please work on that as well. Package names should be all lowercase and class names should be CamelCase and start with uppercase.
I am to do a web application with JSF, just to get and put a value from the JSF to bean and vice versa. I think I have done everything properly but when I start the server and try to access my first page I get the following error
SEVERE: Servlet.service() for servlet [jsp] in context with path [/SimpleJSF] threw exception [/greeting.jsp (line: 20, column: 85) #{...} is not allowed in template text] with root cause
org.apache.jasper.JasperException: /greeting.jsp (line: 20, column: 85) #{...} is not allowed in template text
I am using Eclipse Helios with JDK 1.6 , apache Tomcat 7 and JSF 2.0 framework
Here is my code snippet

In JSF 2.0, JSP is been deprecated as view technology and succeeded by Facelets. You need to rename your .jsp files to .xhtml files. In your case you also need to remove the entire <%# page %> line in both JSPs. Then you need to invoke them with the .xhtml extension in the URL.
Further, you also need to remove the ConfigureListener from web.xml and you need to rename the JSP welcome file to XHTML. I'd also suggest to use *.xhtml instead of /faces/* as FacesServlet URL pattern. This way you don't need to put a /faces/* in URLs everytime. Finally you need to remove the bean from faces-config.xml and annotate the bean as follows instead of those javax.ejb annotations:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
#ManagedBean
#RequestScoped
public class ResultNumber {
After all, it seems that you were reading JSF 1.x tutorials and mixing it up with JSF 2.x. You should be extremely careful what JSF version the JSF book/tutorial you're reading target. Since JSF 2.0 a lot of things are done differently.
You are using .jsp files,so you should import the taglibs manually.Add these two lines right above your opening html tag.
