I'm just in the decision to switch logging from log4j to LOGBACK + slf4j my current OSGI installation: bundle com.springsource.org.apache.log4j -- exporting all log4j packages bundle myLog4jproperties -- fragment-Host: com.springsource.org.apache.log4j -- containing my log4j.-xml as configfile at root of sourcefolder this works well ------- now I'm using following bundles: bundle com.springsource.ch.qos.logback.core -- exporting logback.core packages bundle com.springsource.ch.qos.logback.classic -- importing logback.core -- exporting logback.classic packages -- exporting org-slf4j.impl bundle com.springsource.slf4j.api -- importing org-slf4j.impl -- exporting org.slf4j, org.slf4j.helpers, org.slf4j.spi bundle com.springsource.slf4j.org.apache.commons.logging -- importing org.slf4j, org.slf4j.spi -- exporting org.apache.commons.logging + impl this works well: * in my own bundles I can log directly to logback * 3rdparty bundles using JCL now are logging over slf4j I also have 3rdparty bundles using log4j, so I tried: bundle com.springsource.slf4j.org.apache.log4j -- importing org.slf4j, org.slf4j.spi -- exporting org.apache.log4j this fails :-( the 3rdPartyBundle is using log4j.xml, but this packages wasn't provided from the bridge log4j over slf4j so I still have to use log4j together with slf4j / logback. this works well :::: my questions::::::::::: * can I automatically convert my log4j.xml configfile into logback.xml ? * where to place the logback.xml ? I think, a fragment of logback.classic with logback.xml at root of sourcefolder would be good, or would you recommend logback.core ? * when using JCL over slf4j (logback) - am I right that then all configuration would be only into logback.xml ? (* and if perhaps using log4j over slf4j too, then also all config is in logback.xml ?) ekke excuse the posting in logback and slf4j list, I'm new here and dont know who is responsible after finishing my switch I'll blog about it, so other OSGI equinox developers can see how to make it run -- View this message in context: http://www.nabble.com/switching-logging-to-LOGBACK--OSGI--tp19512782p1951278...
