[logback-user] how to redirect system.out/err to a file?

[Zhangguangchao]

Hi, David,
  Thanks for your information, it helps a lot.
  
 But it  seems that sysout-over-slf4j has not supported OSGi yet. And I can't redirect the system.out/err from various bundle which has its own classloader in OSGi environment.  If sysout-over-slf4j works like log4j-over-slf4j, that will be very cool.

Do you have any other advice ? Thanks.

Another question is when I redirect felix-main system.out  into a file,  it casts an exception as follows:

2011-07-21 14:21:48,142 ERROR [Felix Shell TUI] java.lang.ThreadGroup [LogLevel.java:88] Exception in thread "Felix Shell TUI" java.lang.OutOfMemoryError: Java heap space

And in the log file there are lots of '>' which appears on the felix terminal console. It seems that '>' is printed by felix and then redirected to sysout-over-slf4j. However it has too many '>' and SLF4JPrintStreamImpl goes down. Am I right?
Is this a bug of sysout-over-slf4j?

Here is a list I use: felix 3.2.0, slf4j-api-1.6.1, logback-* -0.9.28 and sysout-over-slf4j-1.0.2. 
Any advice?

Dominic,

That work mentioned by rob was done, and he sent a notification to this this a while back.

You can find all the instructions here: http://projects.lidalia.org.uk/sysout-over-slf4j/

There are some restrictions, so do read the docs.

Hi,
Is there a configuration to redirect STDOUT to a file?
By the way, I found the same question asked in http://www.qos.ch/pipermail/logback-user/2009-June/001141.html and I wanna know whether it is fixed and how. And I didn't found the new feature about ConsoleAppender configuration changed in Logback News.

Thanks a lot.

Dominic Zhang
