advantages of soap
SOAP is both platform and language independent.
SOAP separates the encoding and communications
protocol from the runtime environment.
Web service can retrieve or receive a SOAP
user data from a remote service, and the
source’s platform information is completely
independent of each other.
Everything can generate XML, from Perl
scripts through C++ code to J2EE app servers.
It uses XML to send and receive messages.
It uses standard internet HTTP protocol.
SOAP runs over HTTP; it eliminates
firewall problems. When protocol HTTP
is used as the protocol binding, an
RPC call will be automatically assigned
to an HTTP request, and the RPC response
will be assigned to an HTTP reply.
Compared to RMI, CORBA and DCOM, SOAP
is very easy to use.
SOAP acts as a protocol to move information
in a distributed and decentralized environment.
SOAP is independent of the transport protocol
and can be used to coordinate different protocols.
