Is there a way to inject an EJB into a custom Resource Bundle

Question

I'm trying to build a resource bundle that get its messages from a database, rather than a properties file. I did some tests extending ResourceBundle, ResourceBundle.Control and ListResourceBundle, and I guess I'm on the right path.

I just reach a point when I need to query the actual database to fetch the messages from the my ResourceBundle implementation. I would like to leverage all the JPA infrastructure I have on the EJB layer in order to run the queries and instantiate the objects that will store the keys, messages and locales. So it would be just perfect if I could @EJB-inject my session bean into the ResourceBundle, but I cannot find a way to do it.

Here is my ResourceBundle code:

@ManagedBean(eager=true)
@ApplicationScoped
public class ResourceDicWeb extends ListResourceBundle {

@EJB
private MyDAO myDAO;

@Override
protected Object[][] getContents() {
    List<DicWeb> dicWeb = updateDictionary();

    Object[][] content = new Object[dicWeb.size()][2];

    for(int i = 0; i <= dicWeb.size(); i++) {
        content[i][0] = dicWeb.get(i).getAtrKey();
        content[i][1] = dicWeb.get(i).getAtrMessage();
    }

    return content;
}

    private List<DicWeb> updateDictionary() {
        return myDAO.fetchDictionary(); // at this point myDAO is always null
    }

}

My next step would be to use old-fashioned jdbc to create a database connection directly from the resourcebundle, but this is definitely the last option.

Cheers!

If the injection doesn't work then you should still be able to do this via JNDI.

Context ctx = new InitialContext();
MyDao myDao = (MyDao) ctx.lookup("myapp/myejbmodule/MyDao!org.myapp.ejb.MyDao");
