Trying to create new entity, instead I get: javax.ejb.EJBException: javax.ejb.CreateException: Could not create stateless EJB - ejb

Question

I'm trying to implement a function in my application to create an entity. I have tried coding analog to sample code of my professor which works. Instead I get an exception upon trying to create a new article.
My class: Article.java
#Entity
#Inheritance(strategy = InheritanceType.JOINED)
#Table(name = "ArticleData")
#NamedQuery(name = "Article.getArticle", query = "Select a from Article a where a.articleName = :articleName and a.articlePrice= :articlePrice")
public class Article implements Serializable{
private double articlePrice;
#Id
private String articleName;
public Article(){
}
public Article(String articleName, double articlePrice){
this.articleName = articleName;
this.articlePrice = articlePrice;
}
The Bean: ArticleBean.java
#Named
#SessionScoped
public class ArticleBean implements Serializable{
private static final Logger logger = LogManager.getLogger(ArticleBean.class);
private static final long serialVersionUID = 7730144564841961508L;
#EJB
private ArticleController articleController;
private Article articleData;
public ArticleBean() {
}
//Trying to do this
public String addArticle(){
String forward, caption, msg;
logger.debug("initiate adding of article");
FacesContext contect = FacesContext.getCurrentInstance();
articleController.newArticle(articleData.getArticleName(), articleData.getArticlePrice());
return "addarticle.xhtml";
}
ArticleController.java
#Stateless
public class ArticleController {
#EJB
ArticleFacade articleManager;
private static final Logger logger = LogManager.getLogger(AccountController.class);
public void newArticle(String articleName, double articlePrice){
logger.info("try to create article " + articleName);
logger.info("price: " + articlePrice);
Article newArticle = new Article(articleName, articlePrice);
try{
articleManager.create(newArticle);
}catch (Exception e){
logger.error(e.getMessage());
}
}
ArticleFacade.java
public class ArticleFacade extends AbstractFacade<Article>{
#PersistenceContext(unitName = "examAdminPU")
private EntityManager em;
public ArticleFacade() {
super(Article.class);
}
#Override
public EntityManager getEntityManager() {
return em;
}
public void setEm(EntityManager em) {
this.em = em;
}
}
Here is a sample of the stacktrace

Answer 1

I resolved it. I forgot to annotate that ArticleFacade.java is stateless.
#Stateless
public class ArticleController {
#EJB
ArticleFacade articleManager;
private static final Logger logger = LogManager.getLogger(AccountController.class);
public void newArticle(String articleName, double articlePrice){
logger.info("try to create article " + articleName);
logger.info("price: " + articlePrice);
Article newArticle = new Article(articleName, articlePrice);
try{
articleManager.create(newArticle);
}catch (Exception e){
logger.error(e.getMessage());
}
}
public void changeArticle(String articleName, double articlePrice){
logger.info("try to edit article " + articleName);
Article editArticle = new Article(articleName, articlePrice);
try{
articleManager.edit(editArticle);
}catch (Exception e){
logger.error(e.getMessage());
}
}
public void destroyArticle(String articleName, double articlePrice){
logger.info("try to remove article" + articleName);
Article deleteArticle = new Article(articleName, articlePrice);
try{
articleManager.remove(deleteArticle);
}catch (Exception e){
logger.error(e.getMessage());
}
}
}
