connector and tomcat 4.1.12 !!

[Max]

Hi

I have a tomcat 4.1.12, an apache 2.0.40 and mod_jk2 (tomcat-connectors-4.1.12)

since i put this simple jk2.properties in my $CATALINA/conf dir :
#
handler.list=apr,channelUnix,request
channelUnix.file=${jkHome}/work/jk2.socket
apr.NativeSo=${jkHome}/lib/libjkjni.so

(it works great with a tomcat 4.1.10)
tomcat doesn't start and my catalina.out looks like this :

Starting service Tomcat-Standalone
Apache Tomcat/4.1.12-LE-jdk14
24 oct. 2002 17:26:38 org.apache.jk.server.JkMain newHandler
GRAVE: Can't create apr
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
        at org.apache.jk.apr.AprImpl.<clinit>(AprImpl.java:340)

        at java.lang.Class.forName(Class.java:130)
        at org.apache.jk.server.JkMain.newHandler(JkMain.java:494)

and the socket file is not created .

Can you help me ?

THANKS !
