Eclipse EAR project problem

Question

Hello,

I've created an Enterprise Application Project in Eclipse. Then i created an EJB project, and i checked "Add project to an EAR", and i selected the EAR project. In the EJB Project i checked a checkbox so that i create the EJBClient and EJBEAR projects too (see the image)

If i create an interface in the EJBClient project, the changes are not reflected in the EJB Project, and i have set a dependency for carteDeBucateEJB, to carteDeBucateEJBClient. If i create an interface on the Client, why does not appear automatically in the EJB Project the implementation for this interface?

Thanks!
