What is SOAP Web Service? A SOAP Web service is a Web service implemented using the SOAP protocol.

SOAP (Simple Object Access Protocol) is a communication protocol that defines how a message should be constructed, transmitted from one node to another, and processed by each node as shown in the following diagram:

SOAP node          
 |
 | Construct an initial SOAP message
 | Bind the initial message for transmission
 | Transmit the initial message
 v
 ----------> SOAP node
              |  
              | Receive the initial message
              | Process some part of the initial message
              | Reconstruct an intermediate SOAP message
              | Bind the intermediate message for transmission
              | Transmit the intermediate message
              v
              ----------> SOAP node
                           |
                           | ...
                           v
                           ----------> SOAP node 
                                        |
                                        | Receive the final message
                                        | Process the final message
                                        v
                                        Done 

The current version of SOAP is SOAP 1.2 specification, which is divided into two parts.
