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

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 appreaciated. 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,

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

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

Hi.

I still have the error. The solution described in the last post, did not solve my problem

Best regards,

@Felix Sima
As you have already identified, dependency injection will work only in managed classes and 'MagazinDAO' is'nt a managed class. As for the error still coming, could you post the persistence.xml you used to configure the datasource.

Hello.

Now it finally works

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

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
