JAX-RPC hides
this complexity from the
|
|
|
application
developer.
|
|
|
• |
On the server
side, the developer specifies
|
|
|
the remote
procedures by defining methods
|
|
|
in an interface.
|
|
|
• |
The developer
also codes one or more
|
|
|
classes that
implement those methods.
|
|
|
• |
Client programs
create a proxy, a local object
|
|
representing the
service, and then simply
|
|
|
invokes methods
on the proxy.
