What is difference between static remote method invocation and dynamic remote method invocation?

Answer 1

Typical way for writing code that uses RMI is similar

to the process for writing RPC

❍ declare the interface in IDL, compile the IDL file to generate

client and server stubs, link them with client and server side

code to generate the client and the server executables

❍ referred to as static invocation

❍ requires the object interface to be known when the client is

being developed

❒ Dynamic invocation

❍ the method invocation is composed at run-time

invoke(object, method, input_parameters, output_parameters)

❍ useful for applications where object interfaces are

discovered at run-time, e.g. object browser, batch processing

systems for object invocations, "agents"

Answer 2

Static polymorphism:

• memory allocated at compile time is called as static allocation.
• java resolves calls to overloading methods at compile time is called as Static polymorphism.

Dynamic polymorphism:

• memory allocated at run time is called as dynamic allocation
• java resolves calls to overloading methods at run time is called as Dynamic polymorphism or Dynamic binding or Dynamic dispatch.
• This principle is used to create reference variable.
