How to log the output of a daemon application?

Question

I have a Java program running as a daemon (thanks to YAJSW, a wrapper for java).

The thing is that this java application writes several lines of console text, (simply imagine a Hello World App). If I run it from the console of course I can read those lines.

But when it runs as a daemon, where do those lines of text go?

Answer 1

Why dont you run the app using svscan (homepage, part of daemontools)?

If you configure correctly you'll have something like this:

app/log/main/current

And the current file is the console output.

I use svscan to run C++, Java, Groovy and linux common services.

Answer 2

I've found how to do it in the Yajsw help,

thanks @Gilles for the guiding

It's enough just to specify in wrapper.conf

wrapper.logfile= <path and filename >

Thanks anyway!
