Re: [jetty-users] Jetty 9 logging question


we need some more info to really help you out.  Firstly, exactly which version of jetty 9?  There are some significant differences between 9.2.x, 9.3.x and 9.4.x in logging.

But if I had to guess, I'd say that you are running 9.4 and have the console-capture module enabled... or 9.3 with the logging module enabled.  Either will capture both stderr and stdout.

Can you list your configuration and modules with:

java -jar $JETTY_HOME/start.jar --list-config --list-modules

and we can yell you more about what to do.  It will either be to disable a module or to replace an etc. file, but we need more info.

Can you share how you had your logging setup in Jetty 8 in more detail?
The Jetty-specific logging implementation has remained largely
unchanged. Were you using a SLF4J implementation before?

Hi Chris,
So far I haven't been able to resolve this. As I said in my previous response last week, in Jetty 8 I just created a RolloverFileOutputStream in my jetty.xml and then use System.setErr (again, in jetty.xml) to redirect stderr to the stream. Since I posted the relevant setup from my jetty.xml I haven't had any response from anyone.

I see that RolloverFileOutputStream still exists in Jetty 9, but with the new module system I have absolutely no idea how to set it up, and I can't find any documentation about it (except of course for the API docs).

>From the lack of response, I guess that this is either a very hard problem or so simple and stupid that no-one can be bothered to answer. I can't tell which it is, because it was extremely simple in Jetty 8 but seems to me to be very hard in Jetty 9. Please tell me it's something really simple and I'm just being stupid...

Please, I need an answer to this, otherwise migration to Jetty 9 is just not going to happen for us!
