Why use ejbs? use spring DI instead ( with annotated security/transactions)

Thanks for the info. I have been struggling with trying to get it working for over an hour. Nice to know that it is not working because it is not supported. I sure wish the JBoss documentation would have included this in big bold letters.

Another post on theserverside.com says about the same problem:

Yes you are right. The dependency injection does not work from Servlets for example. And as the link (http://docs.jboss.org/ejb3/app-server/tutorial/jndibinding/jndi.html) says, I could make the general JNDI work as follows..

InitialContext ctx = new InitialContext();
Converter converter = (Converter)ctx.lookup(“com.ejb3.sample.converter.app/ConverterBean/local”);

I found the same problem after a lot of hair pulling why my servlets gave nullpointerexceptions when using dependency injection.

A solution could be to use JSF in combination with JBoss Seam.

Hi, thanks for this post that confirm my own experience.
I’m looking for a good simple example of Spring 2.5’s Annotation based DI for EJB.
Any help?
