Service Wrapper
Encyclopedia
A service wrapper is a computer program
that wraps
arbitrary programs thus enabling them to be installed and run as Windows Service
s or Unix Daemon
s, programs that run in the background
, rather than under the direct control of a user. They are often automatically started at boot
time. Arbitrary programs cannot run as services or daemons, unless they fulfill specific requirements which depend on the operating system
. They also have to be installed in order for the operating system to identify them as such.
Various projects exist offering a Java service wrapper, as Java itself doesn't support creating system services. Some wrappers may add additional functionality to monitor the health of the application or to communicate with it.
