Hi Everyone :-) i've many troubles getting my FileAppender creating Logfiles. The Logfile itself is created, but it's always empty. I don't know what else i can do??! May someone can have a look at my code and help me out.

i got the following logging: 14:47:05,523 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy] 14:47:05,524 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml] 14:47:05,524 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.xml] 14:47:05,525 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Setting up default configuration. 14:47:05,597 |-INFO in ch.qos.logback.core.FileAppender[null] - File property is set to [/home/stepwalk/AlmiraTestLocal/EclipseTestLogs/RecordingLoopFps_1385646425597.log] is the [null] the problem??

Looks good except that encoders cannot be shared. Try creating to PatternLayoutEncoder instances. On 11/28/2013 2:30 PM, stepwalk wrote:

A second encoder solved it perfectly! A last question is it possible to set a different logging level for each appender programmatically? Do i have to create two logger instances for that? Thanks for your help. Cheers Stephan -- View this message in context: http://logback.10977.n7.nabble.com/Configuring-FileAppender-only-empty-logfi...
