i m new in primefaces can you help me plase i want to fill a dataTable primefaces by data from mysql database table name is products
i got the bean Product as below :
package ma.supmti.jsf.model;
import java.util.Date;
public class Product {
private Integer id;
private String name;
private Integer prixAchat;
private Integer prixVente;
private Date dateCreation;
public Product() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getPrixAchat() {
return prixAchat;
}
public void setPrixAchat(Integer prixAchat) {
this.prixAchat = prixAchat;
}
public Integer getPrixVente() {
return prixVente;
}
public void setPrixVente(Integer prixVente) {
this.prixVente = prixVente;
}
public Date getDateCreation() {
return dateCreation;
}
public void setDateCreation(Date dateCreation) {
this.dateCreation = dateCreation;
}
}
the managedBean ServiceProduct as a service
package ma.supmti.jsf.service;
import java.util.List;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import ma.supmti.jsf.dao.DAOProduct;
import ma.supmti.jsf.dao.IDAOProduct;
import ma.supmti.jsf.model.Product;
#ManagedBean(name = "serviceProduct")
#ApplicationScoped
public class ServiceProduct implements IServiceProduct {
IDAOProduct dao = new DAOProduct();
public ServiceProduct() {
}
public void addProduct() {
dao.addProduct();
}
public List<Product> selectProduct() {
return dao.selectProduct();
}
}
the Product ManagedBean :
package ma.supmti.jsf.presentation;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import ma.supmti.jsf.model.Product;
import ma.supmti.jsf.service.ServiceProduct;
#ManagedBean(name="productM")
#ApplicationScoped
public class ProductMB implements Serializable {
private static final long serialVersionUID = 1L;
private List<Product> produits;
#ManagedProperty("#{serviceProduct}")
private ServiceProduct srvProduct;
#PostConstruct
public void init() {
setProduits(srvProduct.selectProduct());
}
public void setSrvProduct(ServiceProduct srvProduct) {
this.srvProduct = srvProduct;
}
public List<Product> getProduits() {
return produits;
}
public void setProduits(List<Product> produits) {
this.produits = produits;
}
}
and the hibernate dao to load data from mysql database
package ma.supmti.jsf.dao;
import org.hibernate.query.Query;
import ma.supmti.jsf.model.Product;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class DAOProduct implements IDAOProduct {
public DAOProduct() {
}
public void addProduct() {
}
public List<Product> selectProduct() {
Configuration config = new Configuration();
config=config.configure("hibernate.cfg.xml");
SessionFactory sessionFactory = config.buildSessionFactory();
Session session = sessionFactory.openSession();
Query query = session.createQuery("from Product");
List<Product> produits = query.list();
for(Product produit:produits) {
System.out.println("prix "+produit.getPrixAchat());
System.out.println("Prenom "+produit.getPrixVente());
}
return produits;
}
}
here is the dataTable i want to display

I'm using a normal datatable with lazyloading and rowexpansion with a nested table and I have problems by opening the rowexpansion after lazyloading. ScrollRows is setted to 150.
<ui:composition template="/ressources/basic.xhtml" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:p="http://primefaces.org/ui">

<ui:define name="content">
<h:form id="crateTbl">
<p:dataTable rowExpandMode="single" id="cTbl" var="crate" value="#{cratesView.lazyModel}" selectionMode="single"
filteredValue="#{cratesView.filteredCrates}" selection="#{cratesView.selectedCrate}"
lazy="true" liveScroll="true" scrollRows="150"
widgetVar="cratesTbl" rowKey="#{crate.id}" scrollable="true" scrollHeight="550">
<p:column style="width:16px" exportable="false">
<p:rowToggler />
</p:column>
<p:column headerText="#{label['crate.col.grp']}" filterStyle="width:60px;" filterBy="#{crate.grp}" filterMatchMode="contains" width="60">
<h:outputText value="#{crate.grp}"/>
</p:column>
...additional columns of crate.
<p:rowExpansion >
<p:panelGrid columnClasses="label,value" >
<div class="remark-label"><b>#{label['crateview.toggle.remark']}</b>: <h:outputLabel value="#{crate.remark}"/></div>
<p:dataTable id='bTbl' var="bottle" value="#{cratesView.getBottles2Crate(crate)}"

</p:column>
...additional columns of bottle
</p:dataTable>
</p:column>
</p:row>
</p:panelGrid>
</p:rowExpansion>
</p:dataTable>
</h:form>
</ui:define>
and Bean:
#ManagedBean(name = "cratesView")
#ViewScoped
public class CrateView implements Serializable {
//object definitions
#PostConstruct
public void init() {
//init some objects
lazyModel = new LazyCrateDatamodel(cratesList);
}
public LazyDataModel<Crate> getLazyModel() {
return lazyModel;
}
public void setLazyModel(LazyCrateDatamodel lazyModel){
this.lazyModel = lazyModel;
}
public void setSelectedCrate(final Crate c){
this.selectedCrate = c;
}
public Crate getSelectedCrate() {
return this.selectedCrate;
}
public List<Crate> getFilteredCrates() {
return filteredCrates;
}
public void setFilteredCrates(List<Crate> filteredCrates) {
this.filteredCrates = filteredCrates;
}
public List<Bottle> getBottles2Crate(final Crate c)
{
int grp = c.getGrp(); //
return gProvider.getBottlesByCrate(calculated.getGrp(), 0);
}
}
Everything runs fine on the firstpage, opening the expansion shows correct data in the table. After loading the next 150 rows and scrolling back to e.g. the first row and opening the expansion the data of a wrong crate is loaded. cratesView.getBottles2Crate(crate) is called with a crate-object shifted by n*150(n - numbers of loadings). The object of the rowtoggling-event is not the same of the datamodel. On the other side setSelectedCrate gets the right object.
Do I have something misconfigurated or is there a hint in the docs using rowexpansion and lazyloading...
Thanks for some hints.
Edit: Correct some syntax.
Sorry for the missing information:

It's the same behavior: After one loading scrolling to the beginning, the given crate is the 150 shifted crate, not crate[0].
Hope someone can verify this behavior.

I'm trying to have a selectonemenu as filter option in a data table
I've done several tests, with no success
Now I'm trying to create a sample custom filter, with selectOneButton, with static fields, trying to simplify, but again it doesn't work
<p:column filterBy="#{sController.getStatus(se)}" headerText="Stato"
style="text-align:center;" sortBy="#{sController.getStatus(se)}"
filterMatchMode="exact"
>
<f:facet name="filter">
<p:selectOneButton onchange="PF('sDataTableWV').filter()">
<f:converter converterId="javax.faces.Boolean" />
<f:selectItem itemLabel="All" itemValue="" />
<f:selectItem itemLabel="Sold" itemValue="true" />
<f:selectItem itemLabel="Sale" itemValue="false" />
</p:selectOneButton>
</f:facet>
<img src="#{resource[sController.getStatus(se)]}" />
</p:column>
The facet is completely ignored, I see the usual input field instead

I'm on glassfish 3.2
Sorry, I have my development environment with 5.0, but on production was 3.5
changing the library all worked
I am facing an issue while tryin to group data with primefaces subtale component. My columns are grouped but the first result still the same row as shown in the screen shot below :
Normaly I should have other apart from AIR. But this is the result I have got.
Can some one help me understand what happening. I have followed the PrimeFaces show case and develop classes to produce this subtable:
This is the managed bean:

}
}

this is the Master class :

I found, something here about it. It is a Primefaces bug. They recommand to use nested datable instead.
I am about developing a small application using EJB JPA MySQL netbeans7.2,
so my application has the following goal: get the list of names and their IDs and add other names to the list.
My classes are:

Unfortunately, when I invoke the method addEmployee in the jsf page, nothing is written to the database. I was worried about the transaction management handled by the container; that is the updates and inserts are managed by the container and it may not be written to the database immediately, so I annotate the addEmployee method (in the EJB) with the #TransationalAttribute(TransactionalAttributeType.REQUIRED) but the result still the same.
Is there anything that I am missing here in my code or my understanding of the issue's context?
(Note that I am a beginner in EJB :) )
Here are the jsf pages (an index page that shows the list and another one to add new element to the list):
