Hi All I'm having some problems running a logback socket command... Here it is: java ch.qos.logback.classic.net.SimpleSocketServer 6000 \ src/main/java/chapter4/socket/server1.xml I'm in the logback-examples/ folder but still I can't get it to work. I'm getting an exception: Caused by: java.lang.ClassNotFoundException: ch.qos.logback.classic.net.SimpleSocketServer at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Meth at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Sour at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) I'm just following the tutorial.......What am I doing wrong? Thanks for help
