I have a bean that is supposed to retrieve people from a database and then put them in a list which is displayed on the webpage. I keep getting a managed bean injection failure though and it seems to be caused by some sort of link between the database and server getting screwed up.
here is the stack trace.
https://gist.github.com/blaxened/85a6861faf2373c26506
Here is the last part of the server log though it looks very similar to the stack trace.
https://gist.github.com/blaxened/f0bc6028d27cabcbd325
I know for a fact that the database/table is there
Here is my persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

so I am unsure what is wrong. Let me know what other files need to be uploaded if any.
Your Table MYTABLE cannot be found by the Applicationserver. Can you verify that the server is able to connect and find the Table inside the configured datasource?
Can you post your persistence.xml?

[ how can I solve this error? ]
I'm new to JSF, and stuck in a problem.
I have a selectOneMenu for displaying the list of countries. When the user selects one of the country, there's another selectOneMenu having the cities (=regions in my case) should be auto-populated.
I tried several iterations for doing the same but didn't help.
Please let me know if anything else is also needed to help me. Would really appreciate it.
UPDATE:
Here's the code after adding listener:
<p:outputLabel for="countryRegistration">#{msg['country']}:</p:outputLabel>
<p:selectOneMenu id="countryRegistration" value="#{mbcActor.geoData.country}" style="width:120px;" >
<f:attribute name="country" value="java.util.List" />
<f:converter converterId="ViewScopedObjectConverter"/>
<f:selectItem itemLabel="#{msg['selectCountry']}" itemValue=""/>
<f:selectItems value="#{geoLists.countryList}" var="country" itemLabel="#{country.name}"/>
<p:ajax listener="#{mbcActor.geoData.updateRegions}" render="cityRegistration"/>
</p:selectOneMenu>
<p:message for="countryRegistration"/>
<p:outputLabel for="cityRegistration">#{msg['city']}:</p:outputLabel>
<p:selectOneMenu id="cityRegistration" value="#{mbcActor.geoData.region}" style="width:120px;">
<f:attribute name="regions" value="java.util.List" />
<f:converter converterId="ViewScopedObjectConverter"/>
<f:selectItem itemLabel="#{msg['selectCity']}" itemValue=""/>
<!--<f:selectItems value="#{geoLists.regionForCountry}" var="region" itemLabel="#{region.name}"/>-->
<f:selectItems value="#{geoLists.getRegionForCountry(country)}" var="region" itemLabel="#{region.description}"/>
</p:selectOneMenu>
<p:message for="cityRegistration"/>
But it says:

Your <p:ajax> tag uses the render attribute, which isn't predefined. The attribute you want is update.
supposing that registrationHelper.newActor is an instance of of a Managed Bean, I think it's probably not initialized. Why don't you make sure it is, by creating it on RegistrationHelper's PostConstruct, or even get it through a method like
public AbstractActor createNewActor() {
newActor = new AbstractActor();
return newActor;
}
<ui:param name="mbcActor" value="#{registrationHelper.createNewActor}"/>
I'm developing a javaEE project using Glassfish and EclipseLink.
ALthough, when i run my app i get the following exceptions:

Exception Description: The method [_persistence_setjuego_vh] or [_persistence_getjuego_vh] is not defined in the object [model.ConcursosJuego].
Internal Exception: java.lang.NoSuchMethodException: model.ConcursosJuego._persistence_getjuego_vh()
i have no clue why i am getting this exception becuase the Entity "Juegos" has that methods, this is the Entity Code:

i have tried eclipse link persistance and methods in other entities and it does work.
(This is the first entity that have more than 1 relation)
thanks
i have an association table called MenuPrevilege between 2 tables called Menu and Previlege.
In order to get all menus of a specific previlege i created a named query in the Menu entity:
#Entity
#NamedQueries( {
#NamedQuery(name = "getAllMenus", query = "select m from Menu m"),
#NamedQuery(name = "getMenusByPrevilegeId", query = "select m from Menu m
JOIN m.menuPrevilege mp where mp.previlege_id = :p")})
public class Menu implements Serializable {
private String url;
private String description;
private List<MenuPrevilege> menuPrevilges;
private static final long serialVersionUID = 1L;
public Menu() {
super();
}
#Id
public String getUrl() {
return this.url;
}
public void setUrl(String url) {
this.url = url;
}
public String getDescription() {
return this.description;
}
public void setDescription(String description) {
this.description = description;
}
public void setMenuPrevilges(List<MenuPrevilege> menuPrevilges) {
if (menuPrevilges == null)
menuPrevilges = new ArrayList<MenuPrevilege>();
this.menuPrevilges = menuPrevilges;
}
#OneToMany(mappedBy = "menu", cascade = CascadeType.REMOVE)
public List<MenuPrevilege> getMenuPrevilges() {
if (menuPrevilges == null)
menuPrevilges = new ArrayList<MenuPrevilege>();
return menuPrevilges;
}
public Menu(String url, String description) {
super();
this.url = url;
this.description = description;
}
}
i'm having this exception org.hibernate.QueryException: could not resolve property:menuPrevilege , and i don't know how to deal with it. this is the MenuPrevilege entity:
#Entity
#Table(name = "Menu_Previlege")
public class MenuPrevilege implements Serializable {
private IdMenuPrevilege idmenuPrevilege = new IdMenuPrevilege();
private Date activationDate;
private Date deactivationDate;
private Menu menu;
private Previlege previlege;
private static final long serialVersionUID = 1L;
public MenuPrevilege() {
super();
}
#EmbeddedId
public IdMenuPrevilege getIdmenuPrevilege() {
return this.idmenuPrevilege;
}
public void setIdmenuPrevilege(IdMenuPrevilege idmenuPrevilege) {
this.idmenuPrevilege = idmenuPrevilege;
}
#Temporal(TemporalType.DATE)
public Date getActivationDate() {
return this.activationDate;
}
public void setActivationDate(Date activationDate) {
this.activationDate = activationDate;
}
#Temporal(TemporalType.DATE)
public Date getDeactivationDate() {
return this.deactivationDate;
}
public void setDeactivationDate(Date deactivationDate) {
this.deactivationDate = deactivationDate;
}
public void setMenu(Menu menu) {
this.menu = menu;
}
#ManyToOne
#JoinColumn(name = "menu_id", insertable = false, updatable = false)
public Menu getMenu() {
return menu;
}
public void setPrevilege(Previlege previlege) {
this.previlege = previlege;
}
#ManyToOne
#JoinColumn(name = "previlege_id", insertable = false, updatable = false)
public Previlege getPrevilege() {
return previlege;
}
public MenuPrevilege(Menu menu, Previlege previlege) {
super();
getIdmenuPrevilege().setIdMenu(menu.getUrl());
getIdmenuPrevilege().setIdPrevilege(previlege.getPrevilegeId());
this.setMenu(menu);
this.setPrevilege(previlege);
menu.getMenuPrevilges().add(this);
previlege.getPrevilegeMenus().add(this);
}
}
I made name refactoring to my code edit my query and everything seems to be working. Here are the changes :
in the named query:
#NamedQuery(name = "getMenusByPrevilegeId", query = "select m from Menu m JOIN
m.previleges p where p.previlege.previlegeId = :p")})
the entity attribute
private List<MenuPrevilege> previleges;
// getters and setters as well
in the constructor of the MenuPrevilege entity
public MenuPrevilege(Menu menu, Previlege previlege) {
super();
getIdmenuPrevilege().setIdMenu(menu.getUrl());
getIdmenuPrevilege().setIdPrevilege(previlege.getPrevilegeId());
this.setMenu(menu);
this.setPrevilege(previlege);
menu.getPrevileges().add(this);
previlege.getMenus().add(this);
}
as u can notice it was a syntax error in my query that caused the exception.
Hi All

i have two table Sub_category and Items
sub category is own of relational, it contain list of Items
Two class follow:

i have stateless bean for handle subcat such as:
#Stateless
#LocalBean
public class SubCatDAO {
#PersistenceContext(unitName = "mcGrawLibPro-ejbPU")
private EntityManager em;
public List<SubCat> retrieveAllSubCat(){
return em.createNamedQuery("SubCat.findAll").getResultList();
}
public SubCat updateSubCat(SubCat sc){
return em.merge(sc);
}
public void deleteSubCat(SubCat sc){
em.remove(em.merge(sc));
}
public SubCat addSubCat(SubCat sc){
em.persist(sc);
return sc;
}
public void persist(Object object) {
em.persist(object);
}
public List<Category> retrieveAllCat(){
return em.createNamedQuery("Category.findAll").getResultList();
}
public List<Items> getAllItemsSubCat(SubCat sub){
em.refresh(em.merge(sub));
List<Items> items = sub.getItemList();
ArrayList<Items> toReturn = new ArrayList<Items>(items.size());
for(Items iItem : items){
toReturn.add(iItem);
}
return toReturn;
}
// Add business logic below. (Right-click in editor and choose
// "Insert Code > Add Business Method")
}
as you can see in stateless bean of subcat , i have written one method return List
and in JSF Managed Bean of subcat i write one method return List to view (JSF)
such as:
public List<Items> getAllItemsSub(){
return subCatDAO.getAllItemsSubCat(sub);
}
(subCatDAO is Stateless bean)
also in JSF Managened Bean of subcat i inital subcat follow:
public BeanConstructor(){
sub = new SubCat(1);
}
my problem is in view (JSF ) i was print list of items to show to user , but i can't get anything,i just see blank,
my code sample :
<h:ouputText value="#{bean.allItemSub.itemid}"/>
when i print bean.allItemSub it return [] <===
why it empty?
I don't really understand your implementation of the getAllItemsSubCat(SubCat sub) method in your EJB. I would rewrite it like this.
First, add a named query to find Items for given a SubCategory:
#NamedQuery(name = "Items.findBySubCat",
query = "SELECT i FROM Items i WHERE i.subCat = :subCat")
And rewrite the EJB method as follow:
public List<Items> getAllItemsSubCat(SubCat sub){
return em.createNamedQuery("Items.findBySubCat").setParameter("subCat", sub)
.getResultList();
}
Then, activate SQL logging (at the JPA provider level) to make sure the method actually returns something.
