local and remote clients

[gk]

Assuming L and R are the local and remote clients for session bean B,

R can pass its reference for B as a parameter in a method call to L.

what it means ? i can not understand this statement. can anybody help
me to understand it ?

how do i code for it ?



L cannot call methods on R. Doesn't this depend on what R actually
is, and where it is located?

I believe you are getting confused between the local and remote
interfaces in J2EE. Local interfaces are used when the caller co-exists
with the bean, such as in the same container. You need to use remote
interfaces when the call is being made over the network, or in a
separate JVM. Local Interfaces for EJBs were introduced to optimize
inter-JVM calls, as there is no RMI/IIOP involved. I recommend reading
some dev-friendly tutorials on J2EE before writing code - it will help
build your understanding step by step.
