You can. You need to obtain a war without any slf4j jars, which you can do by unpacking the original war, deleting the jars, and repackaging it. You can also build from source with the dist-excl-slf4j or dist-war-excl-slf4j build target. After you have the war without slf4j, then you need to put the proper slf4j and log4j jars into the classpath - for jetty, this is typically lib/ext. See the 4.3.0 download - it has the proper jars in its example/lib/ext directory. Thanks, Shawn
