Here is the screen shot when i run the application .

Looks like the MySQL driver can't be found. Some things to check:
Has the driver JAR been deployed to the serverlet container or
application server?
Have the connection details been verified through
the container console?

How to populate the dropdown list using <s:select> tag and hibernate in?

I am working on a project using Struts2 and Hibernate. After employees successfully log on, they will be brought to a new page displaying an event list. This list will be a dropdown select list. I have successfully written and tested my code for logon part, but when I add the second jsp page with tag, they show me the following exception:
message tag 'select', field 'list', name 'yourEvent': The requested list key 'events' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]
description The server encountered an internal error that prevented it from fulfilling this request.

This is an Hibernate problem. The entity has fields declared to be lazy loaded but the entity is not attached to a valid Hibernate Session to fire the proxies to retrieve the data lazily. From the stacktrace, I cannot be sure if this error is thrown by e.getSalaire().getPersonnel().getCin() or .getSalaire().getMois().getMois() (or maybe both).
I don't know how you configured the session management, probably Spring is handling it. To solve this, you should re attach the entity to a valid Hibernate Session. You can do this by using HibernateTemplate#refresh method from the Spring Hibernate integration classes.

Integration jsf, spring, hibernate. How to inject Spring beans into JSF managed beans?

I'm working on a Java EE project using frameworks JSF 2.1, Spring 3.1.1.Release, hibernate 3.2.1. now i'm in the phase of integrating the three of them.
the build succeeded, i use tomcat server 7. but i get this exception on the the front page.

The naive solution for non-JSF developers would be to simply initialize the variables inside the getter to resolve the null value in the attributes. This is:
public List getListeAnnees() {
listeAnnees = getAnneeMetier().getAllAnnees();
return listeAnnees;
}
public AnneeMetier getAnneeMetier() {
if (anneeMetier == null) {
anneeMetier = new AnneeMetierImpl();
}
return anneeMetier;
}
But this may generate lot of overhead from server in case AnneeMetier#getAllAnnees() retrieves the data from database. This is explained here: Why JSF calls getters multiple times
To solve this, you do two things:
Define the right scope of your bean.
Initialize the necessary data for work using #PostConstruct annotated method.
And this would result in:
Defining the scope as #ViewScoped (explained in the link above).
Initializing listeAnnees in #PostConstruct method.
Remove any business logic from getters/setters
So the code would look like this:
#ManagedBean
#ViewScoped
public class AnneeBean {
private AnneeMetier anneeMetier;
private List<Annee> listeAnnees;
#PostConstruct
public void init() {
anneeMetier = new AnneeMetierImpl();
listeAnnees = anneeMetier.getAllAnnees();
}
public List getListeAnnees() {
return listeAnnees;
}
public void setListeAnnees(List listeAnnees) {
this.listeAnnees = listeAnnees;
}
public AnneeMetier getAnneeMetier() {
return anneeMetier;
}
public void setAnneeMetier(AnneeMetier anneeMetier) {
this.anneeMetier = anneeMetier;
}
}
BUT since you're trying to integrate JSF with Spring, you have to take into account that Spring has not yet full support of JSF 2 #ViewScoped annotation. For this case, you have/need to implement it yourself. There are plenty examples on the net about this, and looks that the most popular is from Cagatay's. In this way, you'll be able to gain power from both sides. And your bean will look like this:
#Component
#Scope("view")
public class AnneeBean {
#Autowired
private AnneeMetier anneeMetier;
private List<Annee> listeAnnees;
#PostConstruct
public void init() {
listeAnnees = anneeMetier.getAllAnnees();
}
public List getListeAnnees() {
return listeAnnees;
}
public void setListeAnnees(List listeAnnees) {
this.listeAnnees = listeAnnees;
}
}
More info:
Bean properties are shared across different sessions
Since you're learning Spring, the best bet would be to enable component scan and use annotations to configure your spring beans. Do the following:
Remove any bean configuration in applicationContext.xml.
Add this configuration to enable bean scan annotations:
<!--
These will enable component scan by annotation configuration
rather than XML configuration. One per package
-->
<context:component-scan base-package="dao" />
<context:component-scan base-package="model.services" />
Or if all your classes are inside one root package.
<!--
Assuming there's a root package for your packages like this
<context:component-scan base-package="com.myproject.dao" />
<context:component-scan base-package="com.myproject.model.services" />
-->
<context:component-scan base-package="com.myproject" />
Start configuring your Spring managed beans by annotations:
#Repository
public class AnneeHibernateDao implements AnneeDao{
//...
}
#Service
public class AnneeMetierImpl implements AnneeMetier{
#Autowired
private AnneeDao anneeDao;
//...
}
Compile your project and run it.

You are using getListeAnnees where you intend to call a method of your private object called anneeMetier, which is not initialized yet. You initialize that object through your setAnneeMetier method, which is never initialized in your code, therefore it is null. You can solve your problem by doing one of the following:
You initialize anneeMetier by calling the setAnneeMetier before you use getListeAnnees
You implement a constructor for your AnneeBean class where you initialize anneeMetier
You modify your getter (getListeAnnees) to be such as follows:
public List getListeAnnees() {
if (anneeMetier == null) {
return new ArrayList<Annee>();
}
listeAnnees = anneeMetier.getAllAnnees();
return listeAnnees;
}
EDIT: pL4GU33's comment might be useful, so I add his comment's idea to the answer:
public List getListeAnnees() {
if (anneeMetier == null) {
return Collections.emptyList();
}
listeAnnees = anneeMetier.getAllAnnees();
return listeAnnees;
}
His solution is more type-agnostic, so I upvote his comment.

Closed 7 years ago.
I'm using netbean 7.0.1, glassfish 3.1, primefaces 2.2.1.
This is view
<ui:define name="content">
<h:form enctype="multipart/form-data">
<p:wizard>
<p:tab title="Tab 01">
<p:panel header="This is tab 01">
<h:messages errorStyle="color:red"/>
<h:panelGrid>
<h:selectOneMenu value="#{sellerController.currentCity}">
<f:selectItems value="#{cityController.listCity}" var="obj" itemLabel="#{obj.name}" itemValue="#{obj}"/>
</h:selectOneMenu>
</h:panelGrid>
</p:panel>
</p:tab>
<p:tab title="Tab 02">
<p:panel header="This is tab 02">
<h:panelGrid>
<p:commandButton value="Save" action="#{sellerController.addProperty()}"/>
</h:panelGrid>
</p:panel>
</p:tab>
</p:wizard>
</h:form>
</ui:define>
also try with
<h:selectOneMenu value="#{sellerController.currentCity}">
<f:selectItems value="#{cityController.itemsAvailableSelectOne}"/>
</h:selectOneMenu>
When i click next button on tab 01 and save button on tab 02, sellerController.currentCity return null value. Save button still call : "addProperty()". I got this error

i have two controller, this is CityController :
#Named(value = "cityController")
#SessionScoped
public class CityController implements Serializable {
#EJB
CityModel cityModel;
List<City> listCity;
/** Creates a new instance of CityController */
public CityController() {
}
public List<City> getListCity(){
if (listCity==null) {
listCity = new ArrayList<City>();
listCity = cityModel.findAll();
}
return listCity;
}
public SelectItem[] getItemsAvailableSelectMany() {
return JsfUtil.getSelectItems(cityModel.findAll(), false);
}
public SelectItem[] getItemsAvailableSelectOne() {
return JsfUtil.getSelectItems(cityModel.findAll(), true);
}
#FacesConverter(forClass = City.class)
public static class CityControllerConverter implements Converter {
#Override
public Object getAsObject(FacesContext facesContext, UIComponent component, String value) {
if (value == null || value.length() == 0) {
return "";
}
CityController controller = (CityController) facesContext.getApplication().getELResolver().
getValue(facesContext.getELContext(), null, "customerController");
return controller.cityModel.find(getKey(value));
}
java.lang.Integer getKey(String value) {
java.lang.Integer key;
key = Integer.valueOf(value);
return key;
}
String getStringKey(java.lang.Integer value) {
StringBuffer sb = new StringBuffer();
sb.append(value);
return sb.toString();
}
#Override
public String getAsString(FacesContext facesContext, UIComponent component, Object object) {
if (object == null) {
return null;
}
if (object instanceof City) {
City o = (City) object;
return getStringKey(o.getId());
} else {
throw new IllegalArgumentException("object " + object + " is of type " + object.getClass().getName() + "; expected type: " + CityController.class.getName());
}
}
}
}
This is SellerController
#Named(value = "sellerController")
#SessionScoped
public class SellerController implements Serializable {
#EJB
CityModel cityModel;
private City currentCity;
/** Creates a new instance of SellerController */
public SellerController() {
}
public City getCurrentCity() {
if (currentCity==null) {
currentCity = new City();
}
return currentCity;
}
public void setCurrentCity(City currentCity) {
this.currentCity = currentCity;
}
public void addProperty(){
System.out.println("Call from Save button ?? ");
}
}
This is JsfUtil class
public class JsfUtil {
public static SelectItem[] getSelectItems(List<?> entities, boolean selectOne) {
int size = selectOne ? entities.size() + 1 : entities.size();
SelectItem[] items = new SelectItem[size];
int i = 0;
if (selectOne) {
items[0] = new SelectItem("", "---");
i++;
}
for (Object x : entities) {
items[i++] = new SelectItem(x, x.toString());
}
return items;
}
}
Because of CityController. when i use
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
#ManagedBean(name = "cityController")
#SessionScoped
It's work !

Considering this "cityController"-
#Named(value = "cityController")
#SessionScoped
public class CityController implements Serializable {
Is "customerController" right in the following -
CityController controller = (CityController) facesContext.getApplication().getELResolver().getValue(facesContext.getELContext(), null, "customerController");
Change it to "cityController" as follows -
FacesContext fc = FacesContext.getCurrentInstance();
ELResolver elr = fc.getApplication().getELResolver();
ELContext elc = fc.getELContext();
CityController cc = (CityController) elr.getValue(elc, null, "cityController");

I think your cityModel is NULL. Is your EJB injection configured right?
