Name
UnavailableException
Synopsis
Class Name:
javax.servlet.UnavailableException
Superclass: javax.servlet.ServletException
Immediate Subclasses: None
Interfaces Implemented: None
Availability: Servlet API 1.0 and later
Description
A servlet can throw an UnavailableException at any
time to indicate that it is not available to service client requests.
There are two types of unavailability: permanent (where the problem
will not correct itself and administrative action needs to be taken)
and temporary (where the problem will likely correct itself after
some length of time). To mark a servlet as temporarily unavailable,
specify a duration (in seconds) when constructing the exception.
Well-written servlet containers will use the duration to provide
better error messages to the client. Servlet implementations are
allowed to treat temporary unavailability as permanent
unavailability.
