Re: [Resteasy-developers] Error : Class is not a root ressource

[Edgar A S. <edg...@re...>]

Jean,

I am not sure you can do that directly with EJBs, maybe Bill can confirm it.

However, you can create a "Façade" for you EJB where you can use EJB 
dependency injection capabilities, and so you pojo can can access you 
EJB without problems.

Another architectural issue is that maybe your "Dao" returning String 
you may have problems in layers that are not suitable for REST, such as 
a Swing or even plain JSP pages (whatever JSF or Wicket).
