Java EntityManager throwing NullPointerException

When I try to run the Unit test for this DAO class, I am getting NullPointerException at getById return statement. I know that the class does not initialize the EntityManager, but I don’t understand why? - I can’t tell whether my persistence.xml configuration is wrong or the DB credentials are incorrect.
I saw two or more StackOverflow threads but had had little luck. I am using Intellij IDE.

public AttributeEntity getById(Long id) {
if(id == null) return null;
return entityManager.find(AttributeEntity.class, id);
}

You need to mock the entityManager then you need to do stub for entityManager.find() as shown below.
#Mock // Mocking enitt
private EntityManager entityManager;
public AttributeEntity entity = new AttributeEntity();
// Stubbing for entityManager.find()
Mockito.when(entityManager.find(Mockito.any(AttributeEntity.class), Mockito.any())).thenReturn(entity);

Jersey API with Spring SessionFactory NullpointerException

Images of All Jars
This is the error image from the console.
I am trying to use the Jersey API along with Spring and Hibernate. However, defining session factory says NullPointerException. Can anybody help me to solve this? Added Full configuration with spring, hibernate and Jersey. Images of error and jar on top.

spring3 - application context - bean property name and reference - null pointer exception

All - In the Spring 3.0, in the applicationContext.xml .... are we supposed to have the bean property name and the reference value to be the same ? If I give a different value, it returns null object. But on giving the same value, it works. For my project, i am supposed to give different values for them. Kindly help. bye, HS
This works: (same values)

My Full Code here:

CacheDelegate.java
StatusDBDAO.java

<property name="userDelegate" ref="userDelegate" />
name is the field name in your class. When name is userDelegate, it means that WIRAdminBaseAction has a field named userDelegate (and probably a setter setUserDelegate())
ref is the bean name you want to set this field to. In your example, you should have another bean, named userDelegate or bmoUserDelegate which should be set as userDelegate in WIRAdminBaseAction.
So if you want to use the second configuration:
You just need to create a bean with id bmoUserDelegate:
<bean id="bmoUserDelegate" class="mypackage.BmoUserDelegateClass"/>

JPA/HSQLDB Persistence class not found error

I'm pretty new to JPA and HSQLDB, and I'm havin a weird error when I'm trying to create my EntityManagerFactory. Its a Web Dynamic project in Eclipse (with Tomcat 6.0 as web server) and I imported all the libraries in the the WEB-INF/lib. I'm trying to create the Entity manager Factory in a servlet but in just gives me a class not found exception on the line
emf = Persistence.createEntityManagerFactory("manager1");
Here is the code I used in my servlet:
package view;
import java.io.IOException;
import javax.persistence.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import model.ThemeLivre;
public class AjouterTheme extends HttpServlet {
//private static final long serialVersionUID = 1L;
#PersistenceUnit(unitName ="DB")
private EntityManagerFactory emf;
public AjouterTheme() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
emf = Persistence.createEntityManagerFactory("DB");
EntityManager em = emf.createEntityManager();
String nomTheme = request.getParameter("nomtheme");
String descTheme = request.getParameter("desctheme");
EntityTransaction tx = em.getTransaction();
tx.begin();
ThemeLivre thml = new ThemeLivre(nomTheme, descTheme);
em.persist(thml);
tx.commit();
}
}
Here is my persistence.xml
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="DB" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/DefaultDS</jta-data-source>
<class>model.ThemeLivre</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="hibernate.connection.url" value="jdbc:hsqldb:hsql://localhost/"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
Please tell me what I did wrong, or if there is something I can do.
Thank you

In your servlet code you used
#PersistenceUnit(unitName ="DB")
private EntityManagerFactory emf;
but you declare
<persistence-unit name="manager1" transaction-type="RESOURCE_LOCAL">
change either the one or the other persistence unit name.
Following your input above
Try to add the hibernate persistence provider lib. You add only the specification (API). The implementation itself (hibernate) is needed, to create an Entity Manager.

I've been trying to make a simple class in Java run with JPA to no avail. Help?
The title is the error I'm getting.

You're trying to persist the Transaction and not your entity object.
This is what your code SHOULD look like --
EntityManagerFactory eFactory = Persistence.createEntityManagerFactory("geronimo");
EntityManager eManager = eFactory.createEntityManager();
EntityTransaction eTransaction = eManager.getTransaction();
//eManager.persist(eTransaction); <--- DO NOT DO THIS
eTransaction.begin();
Discography discography = new Discography();
discography.setArtist("Kings Of Leon");
discography.setSong("Radioactive");
eManager.persist(discography); // DO THIS INSTEAD. PERSIST THE ENTITY
eTransaction.commit();
eManager.close();
eFactory.close();
