Simple JPA application on TOMEE

[Prajakta Acharya]

Hi Guys,

I am trying to run a simple JPA application on TOMEE.
I have an EJB which gets reference to EntityManager using annotation. I could successfully look-up EJB and invoke its method, but 'EntityManager' is not getting injected.
This is what I have done:
1) EJB code:

@Stateless(mappedName="AuctionManagerEJBComp")
@PersistenceContext(name = "auctionManagement", unitName = "auctionManagement")

@TransactionManagement(TransactionManagementType.CONTAINER)


public class AuctionManagerImpl implements AuctionManager{
	 @PersistenceContext(name = "auctionManagement", type = PersistenceContextType.TRANSACTION)
	EntityManager entityManager;
	
	
    /**
     * Default constructor. 
     */
    public AuctionManagerImpl() {
        // TODO Auto-generated constructor stub
    	System.out.println("Look-up successful");
    	//entityManagerFactory = Persistence.createEntityManagerFactory("AuctionManagement");
    }
    
    public void createEntity(AuctionEntity auctionEntity){
    	System.out.println("####In createEntity of AuctionManagerImpl, entityManager is "+entityManager);
    	//entityManager.persist(auctionEntity);
    	System.out.println("Creating auction entity");
    }
    
}
	

2) Persistence.xml

<?xml version="1.0" encoding="UTF-8" ?>
<persistence 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" version="1.0">
 
   <persistence-unit name="auctionManagement">
     <description>Auction Application Persistence Unit</description>
   <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
     <!-- <provider>com.objectdb.jpa.Provider</provider>
     <mapping-file>META-INF/mappingFile.xml</mapping-file>
     <jar-file>packedEntity.jar</jar-file> -->
     <class>entity.AuctionEntity</class>
     <class>entity.Bid</class>
     <properties>
       <property name="javax.persistence.jdbc.url"
                 value="jdbc:hsqldb:hsql://localhost/"/>
       <property name="javax.persistence.jdbc.user" value="SA"/>
       <property name="javax.persistence.jdbc.password" value=""/>
     </properties>
   </persistence-unit>
 
</persistence>

Any idea/input would be very helpful....
