Query re. LOGBack, Spring & SLF4J
Hi, I have a question concerning getting LOGBack working with Spring using Maven. According to the Spring Documentation Spring needs to be forced to work iwth SLF4J. (sample code below) My question is how do I get LOGBack to work with this configuration (instead of log4j)? The Spring documentation indicates that you need to use jcl-over-slf4j, but it is not clear how to configure LOGBack to work with Spring and SLF4J. My code, including the example code below builds for me intermiitently from the command line, indicating that there is some classloading issue. Any advice will be much appreciated. Thanks.

There are several waays to make logback, spring and slf4j to work together. Here is the simplest maven dependency declaration which is known to work nicely. <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.0.0.RELEASE</version> <dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> <scope>provided</scope> <dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>0.9.26</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>1.6.1</version> </dependency> <dependencies> HTH, On 08/11/2010 8:32 PM, Seamus Hannan wrote:
