EJB design: Can multiple beans have the same home and remote interfaces?

  1. are there any issues with this?
  2. Yes they can. I'm self using a system where the business logic is made so that every bean have same home and remote interface.

    It can require some application server configuration to get this system wor.

  3. I have a problem that I need a copy of home and remote interface in all ejb-jar files.

    Any solution ?
