This class represents a port to a Service Endpoint Interface. This
class provides access to operations the service provides. Use the
WSUtil class to perform operations on the port such as setting
timeout values and configuring security.
Developers should set a low timeout to ensure responsiveness
of the site and avoid thread exhaustion (see WSUtil.setRequestTimeout(Number, Object)
The default request timeout is 15 minutes when the web reference is used in a job,
and 2 minutes otherwise. If the timeout of the calling script is lower,
the script timeout is used.
