this is usercontroller class,
how to work with this

i have added this in springboot main class
#Bean
public ServletRegistrationBean servletRegistrationBean() {
FacesServlet servlet = new FacesServlet();
return new ServletRegistrationBean(servlet, "*.xhtml");
}
added this in web.xml

NPE in #ManagedBean - javax.servlet.ServletException: An error occurred performing resource injection

I have Spring project, now I want to add few JSF (Primefaces) xhtml pages, but I get null pointer exception in my #ManagedBean on #PostConstruct method when i try get data from existing services?
Do You know how to properly import AuctionViewService to my #ManagedBean? I think that's the problem but I dont know how to fix it :)
Below java classes there's my stacktrace with null pointer (also i mark line with NPE in SalesBean.java)
This is my xhtml page:

If needed i can attach more files and whole project structure, but problem is in importing AuctionViewService to SalesBean, or maybe in mixing JSF and Spring annotations
Ok, I changed #ManagedBean annotation to #Component, link AuctionViewService with #Autowire, and it works for me :) but how can I explain this situation?

JSF xhtml page not found

I've been trying to follow various articles on setting up my first JSF application and can't get my first xhtml page to be found. I keep getting the error "This application has no explicit mapping for /error, so you are seeing this as a fallback" in the browser.
In the browser, I type http://localhost:8080/modelSimulation.xhtml to get this error, and in the console, I see:
... :GET "/modelSimulation.xhtml", parameters={}
... :No mapping for GET /modelSimulation.xhtml
My spring boot application has added the various things required to setup JSF with spring boot, but clearly I'm missing something to be able to view my modelSimulation.xhtml page. What am I missing? Thanks!
I also tried http://localhost:8080 but get corresponding no mapping error too.

I added the 2 required beans to the SpringBootApplication class:
#Bean
public ServletRegistrationBean servletRegistrationBean() {
FacesServlet servlet = new FacesServlet();
return new ServletRegistrationBean(servlet, "*.jsf");
}
#Bean
public FilterRegistrationBean rewriteFilter() {
FilterRegistrationBean rwFilter = new FilterRegistrationBean(new RewriteFilter());
rwFilter.setDispatcherTypes(EnumSet.of(DispatcherType.FORWARD, DispatcherType.REQUEST,
DispatcherType.ASYNC, DispatcherType.ERROR));
rwFilter.addUrlPatterns("/*");
return rwFilter;
}
Here's the backing bean (I don't understand the #Join...)
#Scope(value = "session")
#Component(value = "tradingModelSimulationController")
#ELBeanName(value = "tradingModelSimulationController")
#Join(path = "/modelSimulation", to = "/modelSimulation.jsf")
public class TradingModelSimulationController {
ModelSimulation modelSimulation = new ModelSimulation();
String symbol;
int ranking;
public void apply() {
System.out.println("Applied: " + modelSimulation.toString());
RequestContext.getCurrentInstance()
.execute("handleMsg('applied!');");
}
public ModelSimulation getModelSimulation() {
return modelSimulation;
}
public String getSymbol() {
return symbol;
}
public void setSymbol(String symbol) {
this.symbol = symbol;
}
public int getRanking() {
return ranking;
}
public void setRanking(int ranking) {
this.ranking = ranking;
}
}

Beans not 'managed' using SpringBoot

I use JSF with Spring Boot.
My problem is, that if I use the #javax.faces.bean.ManagedBean annotation I receive
javax.el.PropertyNotFoundException: Target Unreachable, identifier
[numberTest] resolved to null
I resolved the issue with put also the #Component annotation on the managed bean.
The other way was to put the Java classes in the WEB-INF.
My question is: both above-mentioned way seems to be bad and I think that they will cause trouble. What would be the solution to this problem?
I Googled a lot and tried every solution found.
(An additional fact, is that with #javax.annotation.ManagedBean the core JSP functions work (I didn't receive the error) but for example EL doesn't.)
Here is the code, in which with I receive the PropertyNotFoundException:
Configuration.java
import javax.faces.webapp.FacesServlet;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
#SpringBootApplication
#EnableAutoConfiguration
#EnableTransactionManagement
#EnableWebMvc
#Configuration
#EnableJpaRepositories(basePackageClasses = {})
#ComponentScan(basePackageClasses = { CLASSES_ARE_HERE })
public class Configuration {
public static void main(String[] args) {
SpringApplication.run(Configuration.class, args);
}
#Bean
public ServletRegistrationBean servletRegistrationBean() {
FacesServlet servlet = new FacesServlet();
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(servlet, "*.xhtml");
return servletRegistrationBean;
}
}
The managed bean:
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
#ManagedBean
#ApplicationScoped
public class NumberTest {
private int theNumber=0;
public NumberTest() {
}
public void addOne() {
theNumber++;
}
public void addN(int n) {
theNumber+=n;
}
public int getTheNumber() {
return theNumber;
}
public void setTheNumber(int theNumber) {
this.theNumber = theNumber;

here is the bean where I invoked init() method
package com.posts.beans;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import com.posts.models.Users;
import com.posts.services.UsersService;
#SuppressWarnings("serial")
#Component("Usersbean")
#Scope("session")
public class UsersBean implements Serializable{
#Autowired
private transient UsersService us;
private List<Users> lu;
public UsersBean() {
}
#PostConstruct
public void init(){
lu=us.getAllUsers();
System.out.println("hello");//doesn't shw up=init() doesnt work
}
public String getMyname(){
return "mohamed";
}
public List<Users> getLu() {
return lu;
}
public void setLu(List<Users> lu) {
this.lu = lu;
}
}
here is my jsp file ; I tried to show just one field:
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

</table>
<c:forEach var="user" items="${users.lu}">
<p><c:out value="${user.nom}" /></p>
</c:forEach>
</body>
</html>
so the console doesnt show the message "hello" in method init which means that id doesnt work.
maybe it is because that i didnt declare servlet element in web.xm, but i dont have any idea on how it works ..
NB: I tested Services With JUnit, worked fine
i have solved that problem with annotating UserBean class with #Service("userbean") and adding :
<bean id="usersBean" class="com.posts.beans.UsersBean" init-method="init" />
in application-context.xml file ..
when I run my application , i see hibernate generated code of SELECT and the message hello
Hello
Hibernate: select users0_.id as id1_2_, users0_.login as login2_2_, users0_.nom as nom3_2_, users0_.password as password4_2_, users0_.prenom as prenom5_2_ from public.users users0_
" in the console which means that init() method have been executed.
You can make it work in three different ways:
add to your application-context.xml bean that is responsible to work out #PostConstruct annotation:
<bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />
add namespase that already has CommonAnnotationBeanPostProcessor inside:
<context:annotation-config />
or
<context:component-scan base-package="package.with.beans" /> <!-- scans components and adds <context:annotation-config /> -->
define init method in the tag bean of your class for argument "init-method"

PROBLEM:
When I click on the submit button, it shows me the error:
**type Status report
message /Apontador_Web/LoginPage
description The requested resource is not available.**
And When I remove the tags "listener" and "context-param"
it loads the servlet.
What can be happening?
go to glashfish server output and look for an some exception
Tell me the name off exception
print all
You will need to add #WebServlet(urlPatterns={"/LoginPage"}) above your class name i.e public class LoginPage extends HttpServlet {
