hi everyone im new in java EE and i want to developpe an application with EJB and JSF and when i want to inject my JAR in web dynamique project i have this error and i dont understood anything please anyone can help me

This is the interface DAO:
package com.bestofgeeks.gestion.dao;
import java.util.List;
import javax.ejb.Local;
import com.bestofgeeks.gestion.entity.products;
#Local
public interface IGestion {
public void delete(products p);
public products persiste(products p);
public List<products> selectAll();
}
interface DAO
package com.bestofgeeks.gestion.dao;
import java.util.List;
import javax.ejb.Local;
import com.bestofgeeks.gestion.entity.products;
#Local
public interface IGestion {
public void delete(products p);
public products persiste(products p);
public List<products> selectAll();
}
implement DAO
package com.bestofgeeks.gestion.dao.Implement;
import java.util.List;
import javax.ejb.Stateless;
import javax.management.Query;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import com.bestofgeeks.gestion.dao.IGestion;
import com.bestofgeeks.gestion.entity.products;
#Stateless
public class GestionDAOBean implements IGestion{
#PersistenceContext(unitName = "Gestion_PU")
EntityManager entityManager;
#Override
public void delete(products p) {
// TODO Auto-generated method stub
entityManager.remove(p);
}
#Override
public products persiste(products p){
// TODO Auto-generated method stub
entityManager.persist(p);
return p;
}
#Override
public List<products> selectAll() {
// TODO Auto-generated method stub
Query query = (Query) entityManager.createQuery("SELECT o from products o");
return ((javax.persistence.Query) query).getResultList();
}
}
and this is package service of my project
this service have interface Iservice and a package of implement class name ImplServiceProduct
for Iservice this is the code
package com.bestofgeeks.gestion.services;
import java.util.List;
import javax.ejb.Local;
import com.bestofgeeks.gestion.entity.products;
#Local
public interface Iservices {
public List<products> selectAll();
public void delete(products p);
public products persiste(products p);
}
for implement service
package com.bestofgeeks.gestion.services.ImplService;
import java.util.List;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import com.bestofgeeks.gestion.dao.Implement.GestionDAOBean;
import com.bestofgeeks.gestion.entity.products;
import com.bestofgeeks.gestion.services.Iservices;
#Stateless
public class ImplServiceProduct implements Iservices{
#EJB
GestionDAOBean product;
#Override
public List<products> selectAll() {
return product.selectAll();
}
#Override
public void delete(products p) {
// TODO Auto-generated method stub
product.delete(p);
}
#Override
public products persiste(products p) {
// TODO Auto-generated method stub
return product.persiste(p);
}
}
for the entity
package com.bestofgeeks.gestion.entity;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table
public class products {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
#Column
private String nameproduct;
#Column
private String reference;
#Column
private Date dateposte;
public products(String nameproduct, String reference, Date dateposte) {
super();
this.nameproduct = nameproduct;
this.reference = reference;
this.dateposte = dateposte;
}
public products() {
super();
// TODO Auto-generated constructor stub
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getNameproduct() {
return nameproduct;
}
public void setNameproduct(String nameproduct) {
this.nameproduct = nameproduct;
}
public String getRefence() {
return reference;
}
public void setRefences(String reference) {
this.reference = reference;
}
public Date getDateposte() {
return dateposte;
}
public void setDateposte(Date dateposte) {
this.dateposte = dateposte;
}
}
and for my jsf project
i create a controller
this is the code
package com.bestofgeeks.gestion.controllers;
import javax.annotation.ManagedBean;
import javax.ejb.EJB;
import javax.enterprise.context.RequestScoped;
import com.bestofgeeks.gestion.services.Iservices;
#RequestScoped #ManagedBean
public class myProduct {
#EJB
public String name = "noredine";
Iservices service;
}
You must inject the local interface not the bean:
#EJB
IGestion product;
As #kukeltje says in the comment:
Read the error: (emphasis mine) "No EJB found with interface of type
'com.bestofgeeks.gestion.dao.Implement.GestionDAOBean" and what it
references is a impl, not
an interface!

I'm connecting to an Azure SQL database and my next task is to create custom retry logic when a connection has failed. I would like the retry logic to run both on startup (if needed) as well as any time there's a connection failure while the app is running. I did a test where I removed the IP restrictions from my app and that then caused an exception in my application (as excepted). I'd like to handle when that exception is thrown so that I can trigger a job that verifies both the app and the server are configured correctly. I'm looking for a solution where I can handle these exceptions and retry the DB transaction?

The following code may help you create your retry logic for a data source on Spring Boot:
package com.example.demo;
import java.sql.Connection;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.jdbc.datasource.AbstractDataSource;
import org.springframework.retry.annotation.Backoff;
import org.springframework.retry.annotation.EnableRetry;
import org.springframework.retry.annotation.Retryable;
#SpringBootApplication
#EnableRetry
public class DemoApplication {
#Order(Ordered.HIGHEST_PRECEDENCE)
private class RetryableDataSourceBeanPostProcessor implements BeanPostProcessor {
#Override
public Object postProcessBeforeInitialization(Object bean, String beanName)
throws BeansException {
if (bean instanceof DataSource) {
bean = new RetryableDataSource((DataSource)bean);
}
return bean;
}
#Override
public Object postProcessAfterInitialization(Object bean, String beanName)
throws BeansException {
return bean;
}
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#Bean
public BeanPostProcessor dataSouceWrapper() {
return new RetryableDataSourceBeanPostProcessor();
}
}
class RetryableDataSource extends AbstractDataSource {
private DataSource delegate;
public RetryableDataSource(DataSource delegate) {
this.delegate = delegate;
}
#Override
#Retryable(maxAttempts=10, backoff=#Backoff(multiplier=2.3, maxDelay=30000))
public Connection getConnection() throws SQLException {
return delegate.getConnection();
}
#Override
#Retryable(maxAttempts=10, backoff=#Backoff(multiplier=2.3, maxDelay=30000))
public Connection getConnection(String username, String password)
throws SQLException {
return delegate.getConnection(username, password);
}
}
Not sure what you deem custom but, there is an out-of-the-box option with Spring boot and Aspectj by leveraging the pom.xml in the mavern project, as spring-retry depends on Aspectj:
Add the following dependencies in your project pom.xml:
<dependency>
<groupId>org.springframework.retry</groupId>
<artifactId>spring-retry</artifactId>
<version>${version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>${version}</version>
</dependency>
And then add the #EnableRetry annotation to your code:
package com.example.springretry;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.retry.annotation.EnableRetry;
#EnableRetry
#SpringBootApplication
public class SpringRetryApplication {
public static void main(String[] args) {
SpringApplication.run(SpringRetryApplication.class, args);
}
}
The Spring retry module example can be found here: https://howtodoinjava.com/spring-boot2/spring-retry-module/
Im trying to setup mongodb with SpringBoot and im not using context.xml but trying to configure with configuration class and annotations.
package com.configuration;
import com.mongodb.Mongo;
import com.mongodb.MongoClient;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
#Configuration
#EnableMongoRepositories(basePackages = "com.mongo")
public class MongoConfig extends AbstractMongoConfiguration {
#Override
protected String getDatabaseName() {
return "mongodbname";
}
#Override
public Mongo mongo() throws Exception {
return new MongoClient("127.0.0.1", 27017);
}
#Override
protected String getMappingBasePackage() {
return "com.mongo";
}
}
My repository looks like this :
package com.mongo.repositories;
import com.mongo.documents.Sequence;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Repository;
import java.util.List;
#Repository("sequenceRepository")
public class SequenceRepository{
#Autowired
private MongoTemplate mongoTemplate;
public Sequence findOne(Query query){
return this.mongoTemplate.findOne(query,Sequence.class);
}
public List<Sequence> find(Query query){
return this.mongoTemplate.find(query,Sequence.class);
}
public void save(Sequence object){
this.mongoTemplate.save(object);
}
public void delete(Sequence object){
this.mongoTemplate.remove(object);
}
}
If i use like this in the rest controller it is working properly :
package com.controllers;
import com.mongo.documents.Sequence;
import com.mongo.repositories.SequenceRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class IndexController {
#Autowired
private SequenceRepository sequenceRepository;
#RequestMapping("/")
public String index(){
Sequence sequence = new Sequence();
sequence.setClassName("class.Test");
sequence.setActual(1);
sequenceRepository.save(sequence);
return "index";
}
}
But if i want to use the SequenceRepository inside the Sequence document like this :
package com.mongo.documents;
import com.mongo.repositories.SequenceRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
#Document
public class Sequence {
#Autowired
private SequenceRepository sequenceRepository;
#Id
private String id;
private String className;
private int actual;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getClassName() {
return className;
}
public void setClassName(String className) {
this.className = className;
}
public int getActual() {
return actual;
}
public void setActual(int actual) {
this.actual = actual;
}
public void save(){
this.sequenceRepository.save(this);
}
public void delete(){
this.sequenceRepository.delete(this);
}
}
After that I change the code in the controller to :
package com.controllers;
import com.mongo.documents.Sequence;
import com.mongo.repositories.SequenceRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class IndexController {
#Autowired
private SequenceRepository sequenceRepository;
#RequestMapping("/")
public String index(){
Sequence sequence = new Sequence();
sequence.setClassName("class.Test");
sequence.setActual(1);
sequence.save();
return "index";
}
}
I got a nullPointerExceeption at this point in the save() method.
There is no need to inject your Repository inside your Domain object Sequence as it is really bad design to have a dependency between the domain objects and your repository classes.
To follow some good practices, your Service classes or if you don't need a Service layer, your Controller classes should inject your Repository beans.
In your last code snippet your are already doing it, but the .save() method should be called on your repository SequenceRepository and not on the domain object Sequence.
An example could be the following:
#RestController
public class IndexController {
#Autowired
private SequenceRepository sequenceRepository;
#RequestMapping("/")
public String index(){
Sequence sequence = new Sequence();
sequence.setClassName("class.Test");
sequence.setActual(1);
// now let's save it
sequenceRepository.save(sequence);
return "index";
}
}
You can only autowire Spring-managed components into other Spring-managed components. Your sequence object is not a component (not annotated with #Component, #Service, #Repository or #Controller etc.)
I suggest you follow rieckpil's advice.
I have a very famous error, but I can't solve it.
I'm trying to run arqullian test for my application.
I've done everything according to the official documentation.
The long search for solution to the problem given nothing.

Yes, I also think the GcmSenderProducer is missing so the Sender class cannot be injected propperly since it looks like it has no no-arg constructor and I guess the constructor.
I'm developing a RESTful Web Service on JBoss 6 Final with RESTeasy.
I have an external EJB and I want inject EJB on Web Service.
This is the code of EJB
BeanLocalInterface.java
#Local
public interface BeanLocalInterface {
public String sayHello();
}
Bean.java
#Stateless
#LocalBinding(jndiBinding = "BeanLocal")
public class Bean implements BeanLocalInterface {
#Override
public String sayHello() {
return "Hello!";
}
}
In another project I have a WS:
#Path("/ws")
public class HelloWorldResource {
#EJB(mappedName="BeanLocal")
private BeanLocalInterface bean;
#GET
#Path("/hello")
#Produces(MediaType.TEXT_PLAIN)
public String sayHello() {
return bean.sayHello();
}
}
MyRESTApplication.java
public class MyRESTApplication extends Application {
private Set<Object> singletons = new HashSet<Object>();
private Set<Class<?>> empty = new HashSet<Class<?>>();
public MyRESTApplication(){
singletons.add(new HelloWorldResource());
}
#Override
public Set<Class<?>> getClasses() {
return empty;
}
#Override
public Set<Object> getSingletons() {
return singletons;
}
}
bean is alwasy null!
I have tried this solution:
I have put #Stateless on HelloWorldResources
I have create beans.xml in WEB-INF
I have change MyRESTApplication with
#ApplicationPath("wsapp")
public class MyRESTApplication extends Application {
}
Can you help me?
PS: I don't have EAR e I don't want use it
I have managed to solve this. Firstly, remove all settings from web.xml regarding RESTeasy. You only need one adnotation --> #ApplicationPath
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("api")
public class MyRESTApplication extends Application {
//nothing required here, leave this empty
}
This is your session bean interface.
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("MyEJB")
public interface BeanInterface {
#Path("{username}")
#GET
#Produces(MediaType.TEXT_PLAIN)
public String sayHello(#PathParam("username") String username);
}
This is your session bean.
import javax.ejb.Stateless;
#Stateless
public class EJB implements BeanInterface{
#Override
public String sayHello(String username) {
return "Hello, "+username;
}
}

Here is the injected stateful session bean...
package com.ray.TEI.ejb;

import javax.ejb.Stateful;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceContextType;
import com.ray.TEI.model.ExecProcedure;
import com.ray.TEI.model.TestProcedure;
import com.ray.TEI.model.UutSerialNumber;
#Stateful
public class ExecProcedureServiceBean implements Serializable {
private static final long serialVersionUID = 1L;
#PersistenceContext(unitName="jasoni", type=PersistenceContextType.EXTENDED)
protected EntityManager em;
public ExecProcedure createExecProcedure(UutSerialNumber uutSerialNumber, TestProcedure testProcedure) {
ExecProcedure execProcedure = new ExecProcedure();
execProcedure.setUutSerialNumber(uutSerialNumber);
execProcedure.setTestProcedure(testProcedure);
execProcedure.setIterationCount(0);
em.persist(execProcedure);
return execProcedure;
}
}
anyone know what's wrong with this?
Thanks,
Jason
EntityManager is not serializable, I guess that's why it fails.
Couple of options from here:
deactivate passivation (easiest option in case you don't need that mechanism)
remove persistence-context from SFSB (this will most likely kill your EXTENDED mode)
replace EntityManager with Hibernate-Session, which is serializable (consider that experimental, I've never tried it out myself)
