JAX-RPC and SOAP
JAX-RPC -- Java  API for XML-based RPC.
SOAP – Simple Object Access Protocol
In JAX-RPC, a remote procedure call is represented
by an XML-based protocol such as SOAP.
The SOAP specification defines envelope structure,
encoding rules, and a convention for representing
remote procedure calls and responses.
These calls and responses are transmitted as SOAP
messages over HTTP.
