How to create/run a Java Service on UNIX
I neeed to create a service on UNIX.( The program is in Java. this service
will serves an offline application and an online application running with
Tomcat.)
Could you please tell me how to do.
Thanks.

Daxin,
Give the Java Service Wrapper a try.
http://wrapper.tanukisoftware.org/
Tomcat is one of the examples used in the integration documentation:
http://wrapper.tanukisoftware.org/doc/english/integrate-start-stop-nix.html
Cheers,
Leif

Well.... i'm not an expert on phoenix nor james, i "just know" about it
and what it does.... however, you could find some information and
examples at http://james.apache.org/

You should all look at http://jakarta.apache.org/commons/daemon/
There are other wrappers, but this one can be used by Tomcat, I think.
Or is used in some binary distros.

Thank John, Mike, and Tom, and all other repliers.
I hope Tome's instruction will work. I left UNIX for a long time. What Tom
told is familiar to me. I will test it after next week.
It is still a (rare) case that the Sever is not up when one of the
applications talks to it. In this rare case, I can try else way.
Thanks again.

Are you just looking for Unix to start a daemon every time it boots?
That's typically done via a shell script, which accepts "start" &
"stop" arguments (sometimes "start_msg" & "stop_msg", too). These
scripts are in /etc/init.d (/sbin/init.d for HPUX), and there are
corresponding links in /etc/rc.* directories. Your flavor of Unix
will execute these scripts at boot time (with "startup" as the arg).
You just need to make that script execute your application program or
script. Check out the scripts you already have - for example, the
"lp" daemon on my system has the usual shell script and 2 links:
find /sbin -name '*lp*' | xargs ls -l # change /sbin to
/etc, if not HPUX
-r-xr-xr-x 1 bin bin 1604 Oct 27 1997 /sbin/init.d/lp

RE: How to create/run a Java Service on UNIX
Posted by Mike Curwen <g_...@globallyboundless.com>.
I think we should assume that 'the program' will function correctly and do
what it's advertised to do, since if that was the actual problem, then a
list like 'java-rmi-user' or 'java-io-user' would be more appropriate.
The tomcat application, and that second application should be coded to
handle the cases when 'the program' is not available. If that's still a
problem, refer to the aformentioned, fictious(?) groups.
All that remains is "how do I get 'the program' to run?" Oddly enough,
that's still not tomcat-user, but hey we like to help out.
For that (as Yoav said), you need a *nix admin type person to write some rc
scripts for you, or investigate how to do so for yourself. Find a BB or
other email-user list for the exact flavour of *nix you are running, and ask
about rc.d scripts on that list. (rc.d is the approximate equivalent on
*nix, of the Windows Services control panel).

Hi Daxin,
How are you going to genereate the keys? Via the database? Also, seeing
as you are going to use 'service' with & without Tomcat I'd like to know if
either application will be up as long as the server(s) is up. If that's the
case you could have both applications check at startup if the daemon is
active(running) or not not. If the daemon isn't active either application
could start it. If this service should be up whenever the hardware is up
you could start the service on boot so it is in theory always available to
the 2 applications when they are started but each must check if the daemon
is running prior to accessing the daemon.
The person who recommended learning daemons was entirely right and
without my knowing more of the 2 applications I can not tell you more except
since tomcat will access he daemon, I would look closely at the framework in
Jakarta to see if it will suit both applications. I haven't looked at it
closely and it Tomcat must be running for the daemon to be running(which I
doubt) I wouldn't utilize that framework.

First I thank very much for the replies. Please continue forward

this service, written in Java, will serves two applications: one is online

applications will sometimes update the same data tables. This service will
provide unique keys, and do something else for these two applications.
This service will not depend on if Tomcat is running or not.
I want this service on UNIX runs automatically when the computer is started,

Sorry, missed the beginning of this thread but..
I have this book
http://half.ebay.com/cat/buy/prod.cgi?cpid=282172&meta_id=1
and I use it often. It has a very good section on how to create a single or
multi threaded server. It does not go into how to launch this process as
a daemon thread under Unix. I think all you really need to do is launch the
process as a background task by appending the & to the end of the
command line.
Look at the tomcat Catalina.sh as an example of a startup script to run the
service in the background.

this service, written in Java, will serves two applications: one is online
with Tomcat, and another one is an offline application. these two
applications will sometimes update the same data tables. This service will
provide unique keys, and do something else for these two applications.
This service will not depend on if Tomcat is running or not.
I want this service on UNIX runs automatically when the computer is started,
and keep running.
Thanks.

It's very easy to launch a Java daemon in Linux/Unix.
It used to be difficult & require some JNI programming.
On the GNU site I found a slick way someone wronte in
Java and it is simple. What I wanted to know from the
person asking the question is what they're trying to do
with the 'Service'. 'Service' this is Unix not winblows.
Get with the correct lingo! - LOL!

Sorry, missed the beginning of this thread but..
I have this book
http://half.ebay.com/cat/buy/prod.cgi?cpid=282172&meta_id=1
and I use it often. It has a very good section on how to create a single or
multi threaded server. It does not go into how to launch this process as
a daemon thread under Unix. I think all you really need to do is launch the
process as a background task by appending the & to the end of the
command line.
Look at the tomcat Catalina.sh as an example of a startup script to run the
service in the background.

The program is written as Java class. It has Socket read/write features.
Does it requires special functions? How to make it as a service, keep
running and ready to provid data when the Unix box startup?
Thanks.
