SOAP, WSDL, UDDI
SOAP, the simple object application protocol, is a general purpose
distributed object protocol.
-
It can be used for Remote Procedure Calls (RPC) and Plain Document
Transfer.
-
It usually travelles over HTTP, but can also be used with Java Messaging
Service (JMS) and the Simple Mail Transfer Protocol (SMTP).
WSDL, the Web Services Definition Language, gives
instructions for the service. It states where it resides and how
to invoke it. In CORBA, this is the counterpart to the Interface
Definition Language.
UDDI is a registry for connecting procedures and consumers.
-
UDDI Publish API is used by the server, and
-
UDDI Inquire API is used by the client wanting to access the server.
