An example of use of CORBA

Published by Matheus (X-warrior) Bratfisch on September 21, 2010

Hello

CORBA (Common Object Request Broker Architecture) is a standart defined by OMG (Object Management Group), this let distributed object from different languages and OS to communicate. It also provides total transparency in the communication. The IDL (Interface Definition Language) is the tecnology used to describe the interfaces. IDL has your own data types, that are mapped to the data types in other languages. There is an IDL compiler, it generates the codes that do the communication.

But how it works? We have some definitions in a .idl file, in this case Bank-idl (remember to change the filename).

Acessing the files, you will see a lot of definitions like:

Module definition:

module banco {

Definition of data type valor as double

typedef double valor;

Definition of the transacao struct

struct transacao {
unsigned long data; // Formato: ddmmyyyy
string<12> descricao;
valor quantia;
};

Definition of some methos, vars and exceptions

interface auto_atendimento {
readonly attribute string boas_vindas;
valor saldo ( in conta c )
raises ( conta_inval );
void extrato ( in conta c,
out transacoes t, out valor saldo )
raises ( conta_inval );
void transferencia ( in conta origem,
in conta destino, in valor v )
raises ( conta_inval, saldo_insuf );
void investimento ( in conta c,
in aplicacao apl, in valor v )
raises ( conta_inval, saldo_insuf );
};

With this file you can generate a lot of different interfaces compiled to different languages. To generate the interfaces in Java use:

idlj -fall bank.idl

It will generate many files inside a banco folder, with the .java files. Now you just have to code what each method will do.

Example of implementation of a bank service and a client in Java using CORBA and IDL

PS: This is just a introduction to CORBA. It uses a lot of other definitions as Object Management Architecture and others

    Though the sports world loses its mind over the unapologetic showmanship of UFC Freedom 250 unfolding on the South Lawn of the White House, I am treating this precisely like a hot and humid summer show outdoors in Washington, D.C.
