The following page has been changed by GianlucaVarisco: http://wiki.apache.org/tomcat/FAQ/Class_Not_Found ------------------------------------------------------------------------------ * You have fully qualified your class name (eg:{{{ com.bar.package.MyClass }}}) OR * You have imported your class into your jsp (eg: {{{ <%@ pageimport="com.bar.package.MyClass"%> }}}) - ''' Why do I get {{{ java.lang.NoClassDefFoundError: javax/servlet/Filter? }}}''' + ''' Why do I get {{{ java.lang.NoClassDefFoundError: javax/servlet/Filter}}}?''' You probably have servlet.jar floating around somewhere it shouldn't be. This really messes up the classloaders since Tomcat's classloaders don't act quite as normal as one expects (see links above). servlet.jar should only be found only once in $CATALINA_HOME/common/lib. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
