java.lang.RuntimeException: <injection-target> - error

[Felix Sima]

Hello.

During deploying of my ear I get the following error:

java.lang.RuntimeException: <injection-target> could not be found: com.javawebwizard.common.persistence.dao.jpa.BaseDAO.persistentUnitJndi

which really confuses me. I don't know what to check
Any help would be highly appreciated. Please see the code below:

My JSF managed bean:

public class MagazinBackingBean { 
@EJB 
MagazinFacade facade; 
... 

The EJB:

@Stateless 
@PersistenceContext(name = BaseDAO.PERSISTENT_UNIT_JNDI_NAME, unitName="magazinPU") 
public class MagazinFacadeBean implements MagazinFacade { 

@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) 
public void inregistreazaMagazin(String cif) throws JWWException { 
MagazinPO magazin = new MagazinPO(); 
magazin.setCif(cif); 
MagazinDAO dao = new MagazinDAO(); 
dao.insert(magazin); 
} 
} 

MagazinDAO extends BaseDAO:

package com.javawebwizard.common.persistence.dao.jpa; 

public class BaseDAO { 
public static final String PERSISTENT_UNIT_JNDI_NAME = "persistentUnitJndi"; 

@PersistenceContext(name = PERSISTENT_UNIT_JNDI_NAME) 
private EntityManager em; 
... 

The application.xml file:

<?xml version="1.0" encoding="UTF-8"?> 
<description>Magazin</description> 
<display-name>Magazin</display-name> 
<module> 
<ejb>Magazin-ejb.jar</ejb> 
</module> 
<module> 
<web> 
<web-uri>Magazin-war.war</web-uri> 
<context-root>Magazin</context-root> 
</web> 
</module> 
<module> 
<java>common.jar</java> <- BaseDao is in here! 
</module> 
</application>

Thanks,
Felix

Hi.

I think I have understood the problem. I create the DAO using the "new" operator, in a method of the ejb.
At this point the DI has been already performed.

I must put

private EntityManager em;

as a field of the ejb, not in my DAO.

Best regards,
Felix

Hello.

Now it finally works

From my tests it seems that the <injection-target> could not be found ... error is launched when

@PersistenceContext(unitName="somePU") 

annotation is used outside of a managed component.

I also had an error in my persistence.xml. I used "jdbc/someDS" instead of "java:/someDS". I'm using JBoss 5.0.0.GA application server.
Thank you.

Best regards,
Felix
