I'm trying to create a project with glassfish JSF and JPA, but I'm having trouble with the persistence unit in the persistence.xml file.
The error is the following:

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'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.
Whenever I am calling the getFriendList function from the xhtml page I am getting an exception. The page keeps on loading and after that I stop the browser. I get the given stackstrace. Its is telling me that there is an error at line no.78 friends.add(friend); . I think there is something wrong with my syntax. It would be helpful if someone point the error.
1)Here is my FriendBean it is request scoped.
package com.bean;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import javax.faces.context.FacesContext;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;

import javax.persistence.Query;
import javax.servlet.http.HttpSession;
import com.entity.Friend;
import com.entity.User;
public class FriendBean {
Friend friend;
private EntityManager em;
public FriendBean(){
friend = new Friend();
EntityManagerFactory emf=Persistence.createEntityManagerFactory("FreeBird");
em =emf.createEntityManager();
}
public Friend getFriend() {
return friend;
}
public void setFriend(Friend friend) {
this.friend = friend;
}
public List<Friend> getFriendRequestList(){
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
User user=(User) session.getAttribute("userdet");
Query query = em.createQuery("SELECT f FROM Friend f WHERE f.email='"+user.getEmail()+"' AND f.status=0",Friend.class);
List<Friend> results =query.getResultList();
return results;
}
public String friendAccept(String friendRequestId){
System.out.println("friend accept called...");
Friend f=em.find(Friend.class,Integer.parseInt(friendRequestId));
f.setStatus(1);
em.getTransaction().begin();
em.persist(f);
em.getTransaction().commit();
Friend viceversa=new Friend();
viceversa.setEmail(f.getFriendEmail());
viceversa.setFriendEmail(f.getEmail());
viceversa.setStatus(1);
em.getTransaction().begin();
em.persist(viceversa);
em.getTransaction().commit();
return "success";
}
public String friendReject(String friendRequestId){
System.out.println("friend reject called..");
Friend f = em.find(Friend.class,Integer.parseInt(friendRequestId));
em.getTransaction().begin();
em.remove(f);
em.getTransaction().commit();
return "success";
}
public List<User> getFriendList(){
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
User user=(User) session.getAttribute("userdet");
Query query = em.createQuery("SELECT f FROM Friend f WHERE f.email='"+user.getEmail()+"' AND f.status=1",Friend.class);
List<Friend> results =query.getResultList();
ArrayList<User> friends = new ArrayList<User>();
while(results.listIterator().hasNext()){
User friend =em.find(User.class,results.listIterator().next().getFriendEmail());
friends.add(friend);
}
return friends;
}
}
2)Here is the exception that I am getting.

You are clearly running into an issue where your Tomcat server instance has not been allocated enough memory to the JVM heap space. An OutOfMemoryError will be thrown when the allocated heap space has been completely consumed.
You can allocate more through the Tomcat Windows application or you can set in catalina.bat or catalina.sh
Example:
set CATALINA_OPTS=-Xms512m -Xmx512m
I am trying to deploy a simple web service to Glassfish. Here is the web service class:
import com.dv.testrunner.extended.Task;
import com.medallion.etl.exception.StepExecutionException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
*
* #author dvargo
*/
#WebService(serviceName = "Execute")
public class Execute
{
/**
* Web service operation
*/
#WebMethod(operationName = "executeTask")
public boolean executeTask(#WebParam(name = "task") Task task)
{
boolean setUp = task.setUp();
boolean execute;
try
{
execute = task.execute();
}
catch (StepExecutionException ex)
{
Logger.getLogger(Execute.class.getName()).log(Level.SEVERE, null, ex);
return false;
}
return setUp && execute;
}
}
Task is a simple interface. Here is the interface:
package com.dv.testrunner.extended;
import com.medallion.etl.exception.StepExecutionException;
/**
*
* #author dvargo
*/
public interface Task
{
public boolean execute() throws StepExecutionException;
public boolean setUp();
}
When I try to deploy my web service via Netbeans, I get the following error:

Does anyone have any ideas on what is happening and how I may fix it? Is it that I can not use Task as a parameter?
JAX-WS does not allow interfaces as method parameters. Try replacing Task with a class.
Not only JAX-WS does not allow interfaces, it even makes no sense in your case. How would you specify what the task is supposed to do? You need a concrete class as a parameter, and the class needs to be annotated with #XmlRootElement. If you want your endpoint to support different tasks, you will need more operations with different names to achieve that.
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?
The following code seems to throw a NullPointerException at the QuestionRepository class, but I don't managed to fix it. I don't know if I have done anything wrong with the context dependency injection?
Entity
#Entity
#NamedQueries({
#NamedQuery(name=Question.ALL, query="SELECT q FROM Question q")
})
public class Question implements Serializable {
private static final long serialVersionUID = 2402027045394206281L;
public static final String ALL = "Question.all";
Repository
#Named
public class QuestionRepository {
#PersistenceContext(unitName="SertifikatPU")
private EntityManager entityManager;
public List<Question> all() {
TypedQuery<Question> query = entityManager.createNamedQuery(Question.ALL, Question.class);
return query.getResultList();
}
}
EJB
#Local(QuestionLocal.class)
#Stateless
public class QuestionServiceBean implements QuestionLocal {
#Inject
private QuestionRepository questionRepository;
#Override
public List<Question> findAllQuestions() {
return questionRepository.all();
}
}
Backing bean
#ManagedBean
#ViewScoped
public class QuestionIndexBean implements Serializable {
private static final long serialVersionUID = 4228471944163051591L;
#Inject
private QuestionLocal questionBean;
private List<Question> questions;
public void init() {
setQuestions(questionBean.findAllQuestions());
}
public List<Question> getQuestions() {
return questions;
}
public void setQuestions(List<Question> questions) {
this.questions = questions;
}
}

Project structure:
Try to merge the projects in one. Maybe there is a bug in the frameworks when more than one project is used.
Your problem is located at your class QuestionRepository.
If I've read it right, this is a simple class, not a server managed class. What does it mean? It means that due that this cause, this piece of code
#PersistenceContext(unitName="SertifikatPU")
private EntityManager entityManager;
does nothing because the class is instanced by you, nor by the server, so the persistence context is unknown from the point of view of the class. The consequence is that at this other piece of code
public List<Question> all() {
TypedQuery<Question> query = entityManager.createNamedQuery(Question.ALL, Question.class);
return query.getResultList();
}
entityManager will be null so it will cause the null pointer exception.
The solution? Declare QuestionRepository as an EJB too, as example . This way the Persistence Context injection will be automatically done by the server and the entity manager will be initialized at the moment you try to execute the query
