The webservices
platform is used to for interactions between the clients, usually the
browser, and the server. This communication and the results of the communication
are transferred in the form of XML documents.
_______________________________________________
An XML
message is sent across through the internet to an application and the
XML message has the information or the object that has to be executed
at the other end and the results of that is returned in the form of
XML document. Since the communication is done using the internet, the
web service platform uses HTTP and XML in it.
Just remote
invocation alone does not constitute a platform. There is a need for
discovery, transaction, security, and authentication. So, now the other
elements of the platform like SOAP, WSDL, and UDDI come into the picture.
The UDDI
is used as a directory service where the web services are listed so
that others can find out the web services available. WSDL gives the
service characteristics. For transactions, XLANG / XAML are used. For
authentication, XKMS is used.
