In my Java EE 6 / JPA 2 project I have a Map property advantages in the Employee entity:
#ElementCollection
private Map<String, Float> advantages;
The key represents the advantage name and the value represents the cost associated with the advantage name. This is mapped to a table with three columns Employee_Id, Advantages and Advantages_Key. I'd like to persist a Map entry where the Employee_Id is the Id of the selected Employee in the datatable. How can I achieve this?
UpDate: I tried this method in the Employee Business class where I injected the interface EmployeeManagerLocal:
public Map<String, Float> addAdvantage(String advantageName, Float cost, String
employeeId) {
Employee emp = employeeManagerLocal.findById(employeeId);
Map<String, Float> advantages = new HashMap<>();
advantages.put(advantageName, cost);
emp.setAdvantages(advantages);
return advantages;
}
Then, I call this method in the Emlpoyee Managed Bean:
public String addAdvantage(){
employeeBusinessLocal.addAdvantage(advantageName, cost, selectedEmployee.getId());
return "index";
}
But this exception is shown:

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.

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 facing problem with JPA. I have a problem where I need to insert new user and setup its relationship with user at the same time.
==> Database Design is as following:
SystemUsers:
UserName(pk)
Password
SystemClassifiedGroups:
SystemClassifiedGroupName
UserName
==> I have written following logic in EJB
#Override
public void addUser(SYSTEM_CLASSIFIED_USER_GROUPS systemClassifiedUserGroup,
String userName,
String password,
String emailID,
String secretQuestion,
String secretAnswer,
String firstName,
String lastName,
String profilePictureURL,
Date birthDate,
String address1,
String address2,
String cityName,
String zipCode,
short stateID,
short countryID,
String officePhoneNumber) {
FeedBack objFeedBack = null;
String methodName = CLASS_NAME + ".addUser";
try {
SystemUsers objSystemUser=new SystemUsers(userName, password, emailID, firstName, lastName, address1, cityName);
SystemClassifiedUserGroups tempGrp=new SystemClassifiedUserGroups(systemClassifiedUserGroup.name());
States objState = new States(stateID);
Countries objCountry = new Countries(countryID);
objSystemUser.setSecretQuestion(secretQuestion);
objSystemUser.setSecretAnswer(secretAnswer);
objSystemUser.setProfilePictureURL(profilePictureURL);
objSystemUser.setBirthDate(birthDate);
objSystemUser.setAddress2(address2);
objSystemUser.setStateID(objState);
objSystemUser.setCountryID(objCountry);
objSystemUser.setOfficePhoneNumber(officePhoneNumber);
objSystemUser.setZipCode(zipCode);
ArrayList<SystemUsers> lstUser = new ArrayList<SystemUsers>();
lstUser.add(objSystemUser);
tempGrp.setUserName(objSystemUser);
tempGrp.setSystemClassifiedGroupName(systemClassifiedUserGroup.name());
em.persist(tempGrp);
em.persist(objSystemUser);
} catch (Exception ex) {
ex.printStackTrace();
}
}
==> And call the method by following :
asr.addUser(SYSTEM_CLASSIFIED_USER_GROUPS.ADMIN,
"raj",
"pass",
"abc#yahoo.com",
"Color",
"purple",
"Raj",
"Champaneriya",
"abj.jpg",
new Date(),
"jolly1",
"jolly2",
"surat",
"395007",
(short) 1,
(short) 1,
"3201708");
==> But I got following Exception in glassfish console
SEVERE: java.lang.IllegalArgumentException: Object: BusinessFacade.Entities.SystemUsers[ userName=raj ] is not a known entity type.

Thanks in advance
Show me the exact line in the code where the error occurs. I assume it is at the point you call em.persist(tmpGrp). You must save the user first, otherwise the EntityManager will not be able to find any instance of the user, or you need to specify the way the user is managed in the group by adding the following in the group class:
#OneToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE})
SystemUsers userName;
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
