cannot resolve symbol

[Bradberry, Rick]

I have apache and tomcat up and running. Now I'm trying to compile mod_mk2
and get the following error.
Does any one know which jar file I'm missing?
 
[javac]
/export/home/jakarta-tomcat-connectors-4.1.27-src/util/java/org/apache/tomca
t/util/net/PoolTcpEndpoint.java:122: cannot resolve symbol
    [javac] symbol  : class ThreadPoolRunnable 
    [javac] location: class org.apache.tomcat.util.net.PoolTcpEndpoint
    [javac]     ThreadPoolRunnable listener;
    [javac]     ^
 
[javac]
/export/home/jakarta-tomcat-connectors-4.1.27-src/util/java/org/apache/tomca
t/util/net/SSLImplementation.java:114: cannot resolve symbol
    [javac] symbol  : class JSSEImplementation 
    [javac] location: package jsse
    [javac]             return new
org.apache.tomcat.util.net.jsse.JSSEImplementation();
 
Thnak for any help.
