Pardon the interruption, but do I understand correctly that the configuration then isn't XML, but a java string? (if it was XML, this wouldn't be a problem, right? As XML is independent of Java...) :p Kind regards, Koos ________________________________ Van: logback-user-bounces@qos.ch [mailto:logback-user-bounces@qos.ch] Namens Chris Pratt Verzonden: maandag 10 september 2012 17:43 Aan: logback users list Onderwerp: Re: [logback-user] [Question] fileNamePattern in logback.xml There's really nothing to fix, it's a Java limitation. The \ has special meaning, and to escape it you MUST use \\.

I couldn't find any forum. I thought of creating bug in JIRA (http://jira.qos.ch/browse/LOGBACK) but I don't have rights .... So I am dropping mail to given mail id... Coming to bug : ------------------ I am trying to optimize logback.xml file in our environment. Logging directory location we are specifying in more than one location so I am trying to create a variable ( property ) to hold log directory and reuse. Now problem is if path is "D:\seeta\log" then logback is stripping out all back ward slashes and giving it as "D:seetalog". I know if I use forward slash or double slash it works fine but I cannot control the user who use my tool. Can you please help us in fixing it? Working scenario ============= <configuration> ... <fileNamePattern> d:\seeta\log\cd_core.%d{yyyy-MM-dd}.log</fileNamePattern> ... </configuration> NON-Working Scenario ============== <configuration> ... <property name="log.dir" value="d:\seeta\log"/> ... <fileNamePattern>${log.dir}\cd_core.%d{yyyy-MM-dd}.log</fileNamePattern> ... </configuration> NOTE : I have attached logback.jar and configuration files. Here {{logback_working.xml}} is existing configuration and trying to modify to {{ logback_NOT_working.xml}} Regards, Seeta Vadali [X] www.sdl.com <http://www.sdl.com/?utm_source=Email&utm_medium=Email%2BSignature&utm_campaign=SDL%2BStandard%2BEmail%2BSignature> SDL PLC confidential, all rights reserved.
