Can the web container and EJB container be in different Java EE servers for the same web application?

Like the web container is Tomcat and the EJB Container is JBoss?

Is this possible if the Web server and App server are on different machines?

    Yes they can.

    EJBs was initially a distributed architecture based on CORBA. Later (in EJB 2.0) local interfaces were introduced to avoid the expensive cost of distributed communication, but still you can provide remote interfaces to your EJBs to enable access from a remote Java VM.

    From the JavaEE CORBA overview:

    EJBs use the RMI/IDL CORBA subset for their distributed object model,
    and use the Java Transaction Service (JTS) for their distributed
    transaction model. When Enterprise JavaBeans are implemented using the
    RMI-IIOP protocol for EJB interoperability in heterogeneous server
    environments, the standard mapping of the EJB architecture to CORBA
    enables the following interoperability:

    • A client using an ORB from one vendor can access enterprise beans residing on an EJB server provided by another vendor.

    • Enterprise beans in one EJB server can access enterprise beans in another EJB server.

    • A non-Java platform CORBA client can access any enterprise bean object.
