Re: [HAPI-devel] Easiest way to run HAPI ReceivingApplication as standalone app?

[James A. <ja...@ja...>]

Hi Tom,

For what it's worth, we have approached this very problem in the past using
the "Java Service Wrapper" library:
http://wrapper.tanukisoftware.com/doc/english/download.jsp . This is not
trivial by any means, but it's not terrible either and gives a nice way to
have your standalone app install as a windows service or linux daemon (via
init script) with automatic restart if it ever fails.

The Maven appassembler plugin can simplify getting JSW set up a bit, and is
used in the HAPI hl7-over-HTTP "relay" application for just that purpose.
See the plugins section of this
pom.xml<http://sourceforge.net/p/hl7api/code/HEAD/tree/trunk/hapi-mvn/hapi-hl7overhttp/pom.xml>
for
an example.

Depending on what you're doing, this may well be overkill though. If you're
just looking for something you can start by hand occasionally I would just
just build an executable JAR as you have, and kill it with control-C when
done.

Cheers,
James
