Well, I should create an survey application amd the value of the answers is a Long with value from 1 to 6.
I tried many different things but the result is every time:
java.lang.String cannot be cast to java.lang.Long
At the moment this my code:
java class:
...
private HashMap<Questions,Long> itemsHash= new HashMap<Questions,Long>();
private static Map<Long,Long> valutazioni;
static{
valutazioni = new LinkedHashMap<Long,Long>();
valutazioni.put(new Long("1"), new Long("1"));
valutazioni.put(new Long("2"), new Long("2"));
valutazioni.put(new Long("3"), new Long("3"));
valutazioni.put(new Long("4"), new Long("4"));
valutazioni.put(new Long("5"), new Long("5"));
valutazioni.put(new Long("6"), new Long("6"));
}
public Map getValutazioni()
{
return valutazioni;
}
...
public String prepareCreate() {
itemsHash=new HashMap<Questions,Long>();
//-- retrieve all questions from db
List<Questions> qList= getQEjb().findByQuery("select q from Question q order by q.description");
Iterator<Questions> iter=qList.iterator();
Questions q;
//--- initiliazing itemsHash with 1 as default value
while (iter.hasNext())
{
q=iter.next();
itemsHash.put(q,(new Long("1")));
}
selectedItemIndex = -1;
return "Create";
}
public String create() {
try {
List<Questions> qList= getQEjb().findByQuery("select q from Questions q order by q.description");
Iterator<Questions> iter=qList.iterator();
Questions q;
while (iter.hasNext())
{
q=iter.next();
current=new Answers();
current.setAllievo(findAllievo);
current.setData(findData);
current.setIdQuestion(q);
current.setLivello(itemsHash.get(q));
getFacade().create(current);
}
JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("ProgettiQualificaCreated"));
return pqc.prepareList();
} catch (Exception e) {
JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
e.printStackTrace();
return "List";
}
}
the xhtml page is:
<h:outputLabel value="#{bundle.AnswersLabel_data}" for="data" />
<h:inputText id="data" value="#{answersController.findData}" title="#{bundle.AnswersTitle_data}" >
<f:convertDateTime pattern="dd/MM/yyyy HH:mm:ss" />
</h:inputText>
<h:outputLabel value="#{bundle.AnswersLabel_allievo}" for="allievo" />
<h:inputText id="allievo" value="#{answersController.findAllievo}" title="#{bundle.AnswersTitle_allievo}" />
<h:outputLabel value="#{bundle.AnswersLabel_numScheda}" for="numScheda" />
<h:inputText id="numScheda" value="#{answersController.findNumScheda}" title="#{bundle.AnswersTitle_numScheda}" required="true" requiredMessage="#{bundle.AnswersRequiredMessage_numScheda}"/>
<h:outputText value="#{bundle.AnswersLabel_idProgetto}"/>
<h:outputText value="#{answersController.findProgetto}" title="#{bundle.AnswersTitle_idProgetto}"/>
<h:dataTable value="#{questionsController.items}" var="car" rules="all" >
<h:column>
<f:facet name="header">
<h:outputText value="#{bundle.AnswersTitle_idQuestion}"/>
</f:facet>
<h:outputText value="#{car.descrizione}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="#{bundle.AnswersTitle_livello}"/>
</f:facet>
<h:selectOneRadio value="#{answersController.itemsHash[car]}" title="#{bundle.AnswersTitle_idQuestion}" >
<f:selectItems value="#{answersController.getValutazioni()}" />
</h:selectOneRadio>
</h:column>
</h:dataTable>
Where is my error?

My application runs on Glassfish 3.1 and support JSF2.0 and PrimeFaces 3.2 RC1
The problem is that you've bound a generic Map as value of <h:selectOneRadio> as follows
<h:selectOneRadio value="#{answersController.itemsHash[car]}">
But JSF/EL doesn't support generic types. This information is namely not available during runtime. Unless you explicitly specify a converter, EL will not convert/coerce the submitted String value before setting it as Map value.
You need to explicitly specify the default JSF Long converter javax.faces.Long here:
<h:selectOneRadio value="#{answersController.itemsHash[car]}" converter="javax.faces.Long">

I am using primfaces 5 version to show images from my database in datatable, but unfortunately instead of actual images "image" is getting written in column, here is my xhtml file.
I have a list of objects with a StreamedContent property and I need to show it in the component.
i throw the showcase primefaces with no result
<p:dataTable id="dta" value="#{UtilisateurComponent.listUtilisateurs()}" var="current" rows="15" paginator="true" paginatorPosition="bottom" rowKey="current.iduser">
<p:column>
<f:facet name="header">
<h:outputText value="id User" />
</f:facet>
<h:outputText value="#{current.iuser}" />
</p:column>
<p:column >
<f:facet name="header">
<h:outputText value="Photo" />
</f:facet>
<p:graphicImage value="#{UtilisateurComponent.content}" height="100" width="150">
<f:param name="id" value="#{current.iduser}" />
</p:graphicImage>
</p:column>
</p:dataTable>
here is my managed bean :
enter code here
#Scope("session")

}
else{
String imageId = context.getExternalContext().getRequestParameterMap().get("id");
Utilisateur u = utilisateurDAO.findUtilisateurByIduser(Integer.parseInt(imageId));
return new DefaultStreamedContent(new ByteArrayInputStream(u.getPhoto())); //the line that throw the Error
}
}

FacesMessage message = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);

the line (UtilisateurComponentImpl.java:119) is commented on the managedbean Method
StreamedContent getMyContent()
return new DefaultStreamedContent(new ByteArrayInputStream(u.getPhoto()));
In the line above u is null, The problem is that you don't bring him back from DataBase or you imageId is not receivied in the bean.
You can do this
<p:graphicImage value="#{UtilisateurComponent.getContent(current.iduser)}" height="100" width="150"/>
And in the function of yours just get your user id
public StreamedContent getContent(Integer userId){...}
Hope this will help
The problem is with the param passed, you have a dataTable with multiple rows then you send params with the same id.

My persistence.xml in this folder: ~/workspace/K19-Integracao-JSF-JPA/src/META-INF/persistence.xml
I put the mysql connector jar in the glassfish directory:
/opt/glassfish3/glassfish/lib/mysql-connector-java-5.1.30-bin.jar
I'm sorry for posting so much, is that I'm already crazy with this error.
I already searched a lot on the internet and can not resolve the problem, please can someone help me?
I think should always look at the root cause of exception. In your case
Caused by: javax.persistence.PersistenceException:
No Persistence provider for EntityManager named k19pu at javax.persistence.Persistence.createEntityManagerFactory
Your persistence.xml is not valid that's why EntityManagerFactory can't be get created.
due this you are also getting NLP at CarroRepository#buscaTodos method
Caused by: java.lang.NullPointerException at br.com.k19.modelo.CarroRepository.buscaTodos
So Please correct your Persistence.xml and make sure same PU. hope this will solve your problem
Here's the problem:
2014-05-06T12:47:53.049-0300|SEVERE: Error Rendering View[/carros.xhtml] javax.el.ELException: /carros.xhtml #24,58 rendered="#{not empty carroBean.carros}": java.lang.NullPointerException
...
Caused by: java.lang.NullPointerException at br.com.k19.modelo.CarroRepository.buscaTodos(CarroRepository.java:21) at br.com.k19.controle.CarroBean.getCarros(CarroBean.java:30)
Looking until CarroRepository#buscaTodos, line 21 of CarroRepository.java: file, we get this line:
Query query = this.manager.createQuery("select x from Carro x");
The NullPointerException means that EntityManager manager is null.
You have to check why the EntityManagerFactory cannot create a new instance of EntityManager in your JPAFilter servlet filter.
I have a DataTable with a <h:column> as <h:selectBooleanCheckbox>. Both the facet header and the DataTable rows content for that <h:column> are <h:selectBooleanCheckbox>. Below is the code I used:
<h:form>
<h:dataTable
value="#{employeeService.employeeList }"
var="empl"
binding="#{employeeService.dataTablebinding }">
......
......
......
<h:column>
<f:facet name="header">
<h:selectBooleanCheckbox id="chkBoxAll" value="#{empl.checked }" valueChangeListener="#{employeeService.checkAll }" onclick="submit()"></h:selectBooleanCheckbox>
</f:facet>
<h:selectBooleanCheckbox id="tableChkBox" value="#{empl.checked }" valueChangeListener="#{employeeService.getCheckChanged }" onclick="submit()"></h:selectBooleanCheckbox>
</h:column>
</h:dataTable>
</h:form>
When I click the facet header checkbox, I want all the rows checkbox to be checked and the same for unchecked also. This is the code I have for the ValueChangeListener of that facet header checkbox:
public void checkAll(ValueChangeEvent event){
for(Employee empl : employeeList){
employeeList.remove(empl);
empl.setChecked(true);
employeeList.add(empl);
}
}
I am getting the below excception:

Please let me know the reason for this ConcurrentModificationException.
for(Employee empl : employeeList){
empl.setChecked(true);
}
As Luigi stated, you don't need to remove the employee from the list.
It is because while looping over the list you are modifying it:
for(Employee empl : employeeList){
employeeList.remove(empl);
empl.setChecked(true);
employeeList.add(empl);
}
You need to use iterator.
for(Employee empl : employeeList){
// employeeList.remove(empl); //Not required
empl.setChecked(true);
//employeeList.add(empl); //Not required
}
Update As mentioned by Luiggi Mendoza, you don't need to remove and add the element back to the list to alter it. Just take the reference and modify it.
It's not a problem about jsf 1.2. The problem here is that you can't modify a Collection while you are iterating over it.
I think you get the same behaviour doing this:
public void checkAll(ValueChangeEvent event){
for(Employee empl : employeeList){
empl.setChecked(true);
}
}
I'm having a problem here, when i've started work with JSF and JPA. I can't make a jsf "request" using a commandButton to a method in my EJB. Let me show the code:

I won't paste the persistence code, to keep the post clean, the problem is not in this tier.
Thanks in advance!
EDIT:
Sorry! I didn't paste the ManagedBean, here it is:
package model;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import negocio.MapaDeMesas;
import persistence.Mesa;
#ManagedBean
#RequestScoped
public class IndexBean {
#EJB
private MapaDeMesas mp;
private Mesa mesa;
public IndexBean() {
mesa = new Mesa();
}
public void insereMesa(){
mp.insereMesa(mesa);
}
public void setMesa(Mesa mesa) {
this.mesa = mesa;
}
public Mesa getMesa() {
return mesa;
}
}
But now i got another problem the new stacktrace is this one, i can't find the problem with my "getTransaction()" ideas?

Sorry the loooong post!
The first error can be solved by changing the method signature in the facelet.
Change
<h:commandButton id="insertTable" value="OK"
action="#{indexBean.insereMesa(mesa)}">
to
<h:commandButton id="insertTable" value="OK"
action="#{indexBean.insereMesa()}">
The reason of the second error is that methods of an EJB are automatically wrapped in a transaction, so you don't need to call getTransaction(), begin() and commit().
Change
public void insereMesa(Mesa m){
EntityTransaction et = em.getTransaction();
et.begin();
em.persist(m);
et.commit();
}
to
public void insereMesa(Mesa m){
em.persist(m);
}
The same applies to your other EJB method.
Edit: ok you've just updated your post with the bean. Regarding your Transaction error - you can't do bean managed transactions if you're using container managed transactions. You'll have to update your persistence.xml file to not use JTA, or just remove your transaction management code and let the container handle it for you.
You'll need to wrap your EJB inside a JSF (or CDI) managed bean - it seems like you're halfway there by using #{indexBean} but I assume you haven't defined it?
If you update your facelets page (remove the method argument).
<h:commandButton id="insertTable" value="OK" action="#{indexBean.insereMesa()}">
And define a request-scoped managed bean (this one's a JSF one, not CDI) which injects your EJB and defines a method which can be called from your facelets page...
package negocio;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import persistence.Mesa;
#ManagedBean
#RequestScoped
public class IndexBean {
#EJB
private MapaDeMesas mapaDeMesas;
private Mesa mesa;
public Mesa getMesa() {
return mesa;
}
public void setMesa(Mesa mesa) {
this.mesa = mesa;
}
/**
* Called by the command button.
* #return outcome
*/
public String insereMesa(){
mapaDeMesas.insereMesa(mesa);
return null; // navigates to same page (change if required)
}
}
Hope this helps.
I have a servlet that has a suspending method and a broadcasting one:
#GET
#Path("/notification")
#Produces( { "application/x-javascript", MediaType.APPLICATION_JSON })
#Suspend
public JSONWithPadding getNextNotification(
#QueryParam("callback") #DefaultValue("callback") String callback) {
Random random = new Random();
Notification n = new Notification();
n.setMessage("Message is " + Long.toHexString(random.nextLong()));
n.setMessage("S-" + Long.toHexString(random.nextLong()));
return new JSONWithPadding(n, callback);
}
I invoke this from a browser and see the following nice output in my browser:
<!-- ---------------------------------------------------------------- http://github.com/Atmosphere ------------------------------------------------------------------------ -->
<!-- Welcome to the Atmosphere Framework.....
<!-- --------------------------------------------------------------------------------------------------------------------------------------------------------------------- -->
<!-- EOD -->callback({"message":"S-c897404ad5703dcc","sender":null}
So my object is nicely serialized to JSONP.
Now I call my broadcaster method:
#Context Broadcaster bc;
#Broadcast({JsonpFilter.class})
#GET
#Path("/broadcast5")
public Broadcastable broadcast5() {
Random random = new Random();
Notification n = new Notification();
n.setMessage("Message is " + Long.toHexString(random.nextLong()));
n.setMessage("S-" + Long.toHexString(random.nextLong()));
return new Broadcastable(new JSONWithPadding(n, "callback111"), bc);
}
On the server side I get the following exception and nothing is broadcasted:

How could I make my broadcaster work? Do I need to return JSONWithPadding object or only the POJO?
You get an AbstractMethodError. Do you have atmosphere-commons on your classpath?
