I work on ASPLinux 7.2.


I installed:


  • Apache/1.3.22 (Unix)
  • mod_jk-ap13-1.2.0-1
  • tomcat4-4.1.12

and configured:

  • worker.property:

    worker.list=ajp13
    worker.ajp13.port=8009
    worker.ajp13.host=localhost
    worker.ajp13.type=ajp13
    worker.ajp13.lbfactor=1

  • server.xml:


port="8009" minProcessors="5" maxProcessors="75"
enableLookups="true" redirectPort="8443"
acceptCount="10" debug="0" connectionTimeout="20000"
useURIValidationHack="false"

protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>


When I tried to start Tomcat, I received the following catalina.out:


"Starting service Tomcat-Standalone


Nov 26, 2002 7:52:31 PM org.apache.jk.common.ChannelSocket init

When I try to request http://localhost/index.jsp I see NullPointerException


in the catalina.out like this:
