Can't persist or find entities with JPA while tables are already in database

I have a big problem with my DAO class, when I want to persist a new entity, I get a NullPointerException from my wildfly-server.
I have a ManagedBean called VeranstaltungAnlegenMB
package de.mb;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import de.awk.veranstaltungsverwaltung.facade.IVeranstaltungsverwaltungFacade;
#ManagedBean(name="veranstaltungAnlegenMB")
#RequestScoped
public class VeranstaltungAnlegenMB {
#EJB
IVeranstaltungsverwaltungFacade veranstaltungsverwaltungFacade;
private String name;
private String bezeichnung;
private String semester;
private int maxTeilnehmer;
public void veranstaltungAnlegen() {
System.out.println("veranstaltungAnlegen() aufgerufen in VeranstaltungAnlegenMB");
this.veranstaltungsverwaltungFacade.getVeranstaltungAnlegen().veranstaltungAnlegen(this.name,
this.bezeichnung, this.maxTeilnehmer, this.semester);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getBezeichnung() {
return bezeichnung;
}
public void setBezeichnung(String bezeichnung) {
this.bezeichnung = bezeichnung;
}
public String getSemester() {
return semester;
}
public void setSemester(String semester) {
this.semester = semester;
}
public int getMaxTeilnehmer() {
return maxTeilnehmer;
}
public void setMaxTeilnehmer(int maxTeilnehmer) {
this.maxTeilnehmer = maxTeilnehmer;
}
}
The ManagedBean has a method veranstaltungAnlegen(), there I call my class VeranstaltungsverwaltungFacade (a stateless bean), it implements an local bean interface. The class VeranstaltungsverwaltungFacade hold my use cases. My use cases are all stateless beans and implements local bean interfaces too.
Here you see one of my use case class.
package de.awk.veranstaltungsverwaltung.usecase.impl;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import de.awk.veranstaltungsverwaltung.dao.VeranstaltungDAO;
import de.awk.veranstaltungsverwaltung.model.Veranstaltung;
import de.awk.veranstaltungsverwaltung.usecase.ILehrveranstaltungAnlegen;
#Stateless
public class LehrveranstaltungAnlegenImpl implements ILehrveranstaltungAnlegen {
#EJB
private VeranstaltungDAO veranstaltungDAO;
public LehrveranstaltungAnlegenImpl() {
}
#Override
public void veranstaltungAnlegen(String name, String bezeichnung, int maxTeilnehmer, String semester) {
System.out.println(toString() + " starte Methode veranstaltungAnlegen(...)");
Veranstaltung aVeranstaltung = new Veranstaltung(name, bezeichnung, maxTeilnehmer, semester);
System.out.println("Veranstaltung: " + aVeranstaltung.getV_name() + " erstellt");
veranstaltungDAO.save(aVeranstaltung);
System.out.println(toString() + " veranstaltungAnlegen(String name, String bezeichnung, "
+ "int maxTeilnehmer, String semester)");
}
#Override
public String toString() {
return "LehrveranstaltungAnlegenImpl";
}
}
My use case has my DAO class. When I try to save/persist my new entity I get a NullPointerException. I debugged my program and found out that my variable veranstaltungDAO has not been initialized --> null. But I don't know why, because I see in my console that the VeranstaltungDAO is deployed.
'[org.jboss.as.ejb3.deployment] (MSC service thread 1-4) WFLYEJB0473: JNDI bindings for session bean named 'VeranstaltungDAO' in deployment...'
Here you can see my DAO class:
import javax.ejb.Stateless;
import de.awk.dao.GenericDAO;
import de.awk.veranstaltungsverwaltung.model.Veranstaltung;
#Stateless
public class VeranstaltungDAO extends GenericDAO<Veranstaltung>{
public VeranstaltungDAO() {

documentTypeId is primarykey for cd_documentTypes table, this primarykey is used in cd_accounts table as a foreignkey.
If the table having foreignkey relation we must mention the #DynamoDBRangeKey annotation above documentTypeId attribute in Account class. Problem is solved after declared the #DynamoDBRangeKey on top of the attribute documentTypeId.
#DynamoDBRangeKey
private String documentTypeId;
If we want to save or update or delete records in amazon dynamodb using java we must mention the
annotation #DynamoDBHashKey on top of the primarykey column.
#DynamoDBAutoGeneratedKey
#DynamoDBHashKey
private String accountId;
Below is the image shown for foreignkey relation exists in cd_accounts table.
Note:Range key attribute field is displayed if the table is mapping to another table primarykey in amaozong dynamodb.

I think that the clue is in the method name:
[Lcom.dn.vo.User;.<init>()
When we deconstruct that, Spring appears to be trying to invoke a no-args constructor (the <init>() "method") on the type [Lcom.dn.vo.User;. But that type means "array of com.dn.vo.User". And array classes don't have constructors.
I can see some code in your unit test that creates a User[] and appears to pass it as an argment in a POST request to "/createUsers". But the MVC class doesn't have a method that binds to "/createUsers".
Is that right???

Hibernate error org.hibernate.exception.SQLGrammarException: Table ... doesn't exist

Java Student here working on a basic Hibernate project.
Server :tomcat
IDE : Eclipse Juno
I'm trying to persist some data into mySql Db but i've been getting an error every time I click the process button.
The error: org.hibernate.exception.SQLGrammarException: Table 'timdowney.requestdatapersistent' doesn't exist
The name of my DB is : timdowney and it DOES exist.
My Db server works fine because i've tested it with other jdbc apps.
So, my question is: why am i getting an error stating that Table 'timdowney.requestdatapersistent' doesn't exist while timdowney is not a table but my DB name ?
fyi: requestdatapersistent is a my bean class
It's a large code, i agree.

org.hibernate.exception.SQLGrammarException: Table 'timdowney.requestdatapersistent' doesn't exist
Error says schemaname.tablename does not exist, so your schema is timdowney and table name is requestdatapersistent. Since you did not specify any table in Entity it is using bean name as entity name, you need to do either of following:
Create a table named requestdatapersistent
If there is a different table name then provide in annotation using following:
#Entity
#Table(name="request_data_persistent")
Hoping this solves your problem.
Cheers !!

if annotation doesn't work for you, you may try creating hibernate mapping file similar to the below:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="ch5.persistentData.RequestDataPersistent"
table="tablename" catalog="timdowney ">
<id name="ID" type="java.lang.Long">
<column name="id" length="10" not-null="true" unique="true" />
</id>
<property name="EventName" type="String">
<column name="eventname" length="10" not-null="true" unique="false" />
</property>
<property name="hobby" type="String">
<column name="hobby" length="20" not-null="true"
unique="false" />
</property>
....and so on
</class>
</hibernate-mapping>
