RPC, RMI, SOAP, WebService, Corba, COM and other protocols simple description

Recently the system has learned a bit about Java distributed Object Technology, here is a simple summary:

I. RPC protocol

1, JSON-RPC specification: http://json-rpc.org/wiki/specification

2, XML-RPC specification: Http://www.xmlrpc.com/spec

The RPC protocol supports both XML and JSON two-format messages, using HTTP as their transport protocol.

Ii. RMI Agreement

RMI uses JRMP as a message, as you can see, RMI can use more transport protocols, HTTP, TCP can, use Jndi Lookup service.

Third, the SOAP protocol

SOAP Specification: http://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383487

The SOAP protocol uses XML as a message, using HTTP as the transport protocol.

Iv. Web Service

Includes:AXIS,XFire, CFX

Five, CORBA protocol

CORBA uses IDL as a message, uses TCP as the transport protocol , and uses Jndi to find services .

Vi.. com protocol

COM technology was made exclusively by Microsoft, which was developed in Windows 3.1 using OLE technology to support composite documents, experienced several stages such as Ole 2/com, ActiveX, DCOM, and COM +, and currently COM + The message communication module MSMQ and the transaction module to solve the key business MTS are added, which is a relatively complete platform for distributed object calculation.
