In the case of a remote client view, calling any method from the remote home interface and/or remote component interface will be handled via remote method invocation (RMI).

An EJB can use local client view only if it is really guaranteed that other enterprise beans or clients will only address the bean within a single JVM. If this is the case, such access will be carried out with direct method calls, instead of RMI.
