I am having mongodb version 3.0.2 and hibernate-ogm 4.2.0 final with mongodb java version 3.x jars

i wanna create objects with intellij (jpa) system,

You forgot to use the entityManager to persist your new entity. Therefore, jpa does not know about the new entity and nothing is saved.
Just add : em.persist(movie);
The screenshots you provided, in combination with <property name="hibernate.hbm2ddl.auto" value="create" />, suggests that you were not finished creating entity classes when you first run your application. Now if you use hibernate.hbm2ddl.auto = create and there is allready a schema present in your H2, it won't update the schema even though you added one or more entity classes.
The community documentation suggests that you use hibernate.hbm2ddl.auto = update in order to update the schema when the application is run.
Please note that, according to this post, it is not safe to use update in a productive environment.
Despite the best efforts of the Hibernate team, you simply cannot rely on automatic updates in production. Write your own patches, review them with DBA, test them, then apply them manually.
Theoretically, if hbm2ddl update worked in development, it should work in production too. But in reality, it's not always the case.
I hope this helps.
Any one please solve my problem. I'm getting java.lang.reflect.invocationTargetException while I'm trying to save an object into oracle database(Oracle 10G).

I have a few Java Beans written with #Entity annotation. Here's the simplest of those beans.

#GeneratedValue(strategy = GenerationType.IDENTITY)
private int userId;
#NotNull
private String firstName;
#NotNull
private String lastName;
#NotNull
private double handicap;
#OneToMany
private Collection<Score> scores;
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getFirstName() {
return this.firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getLastName() {
return this.lastName;
}
public void setId(int id) {
this.userId = id;
}
public int getId() {
return userId;
}
public void setHandicap(double hcp) {
this.handicap = hcp;
}
public double getHandicap() {
return handicap;
}
#Override
public void setScores(Collection<Score> scores) {
if (this.scores != null){

else{

}
}
#Override

return null;
}
public boolean equals(Object object){
boolean result = false;
if (object instanceof User){
User temp = (User)object;
if (temp.getFirstName().equals(this.firstName)
&& temp.getLastName().equals(this.lastName)
&& temp.getHandicap() == this.handicap){

public String toString(){
String result = ("User: \nID: " + this.userId + "\nName:" + this.firstName + " " + this.lastName + " \nHandicap:" + this.handicap);

}
From my understanding, the persistence.xml file should drop and create all of the tables each time the hsqldb.jar file is run.
I haven't found an issue with my connection (it works when I connect, just no data), my persistence file or location. I originally populated the database this way.
I'm tring to insert my student object to Students table in mydb database, but always get exception. However connecting to table using Connection works properly. I'm using Eclipse with EclipseLink.

One would think that if you want to use EclipseLink, then you would set the "provider" in "persistence.xml", since you have other JPA implementation(s) in the CLASSPATH too, or alternatively you fix the CLASSPATH to make sure there is only 1 JPA implementation present
