Subject mod_jk2/2.0.2 failure in Tomcat 5.0.16 / Apache 2.0.48
Date Tue, 23 Dec 2003 18:42:17 GMT
I've looked at the list archives, but can't find much on JK2 with
Tomcat 5 (though there's plenty of material on Tomcat 4).  I'm sure
I'm missing something obvious, but I can't get even the example webapps 
to work with Apache 2.0.48 / Tomcat 5.0.16 / JK2.  

I am following the example given here (yes, the documentation that
comes with Tomcat 5 refers to this v4.1 page):

  http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/jk2/confighowto.html

My config and log files are below, but in essence here is the problem:

  http://servername/jkstatus           Works -- verify JK module status
  http://servername:8080/jsp-examples  Works -- talk directly to Tomcat
  http://servername/jsp-examples       FAILS -- via JK2 connector


Here are my config files, very simple and based on that confighowto.html:


workers2.properties
--------------------------------

[channel.socket:localhost:8009]
info=Ajp13 forwarding over socket
tomcatId=localhost:8009

# The documentation refers to "examples" but there is no such webapp in 
# Tomcat 5; there is, however, a jsp-examples webapp
#
[uri:/jsp-examples/*]
info=Map the whole webapp
worker=ajp13:localhost:8009

# Set up jkstatus and debug logging
#
[status:status]
info=Status worker, displays runtime info

[uri:/jkstatus/*]
info=Display status info and checks config file for changes
group=status:
worker=status:status

[logger]
level=DEBUG

[logger.file:my_logfile]
level=DEBUG
file=/usr/local/apache/logs/jk2.log

[workerEnv:]
info=Global server options
logger=logger.file:my_logfile
   



jk2.properties
--------------------------------

Empty (i.e. just accept the defaults, e.g. channelSocket.port=8009)

/usr/local/tomcat/logs/localhost_log doesn't indicate any startup problem:

StandardContext[/jsp-examples]ContextListener: contextInitialized()
StandardContext[/jsp-examples]SessionListener: contextInitialized()
StandardContext[/servlets-examples]ContextListener: contextInitialized()
StandardContext[/servlets-examples]SessionListener: contextInitialized()


And /usr/local/tomcat/logs/catalina.out has no errors


Any insights / corrections to my config files would be greatly welcomed.
Thanks.
