Subject: JK2
Hi all,
This is my first attempt at installing JK2 to make Apache -> Tomcat
communication possible. Wasn't successful. Here is an account of events.
If I can get JK2 working, I promise to post a blow by blow diary of how I
went about it. Documentation on JK2 is lacking, following apache.org
documentation hasn't been successful, and I am apparently not alone.
1) Apache 2.0.44 and Tomcat 4.1.18 each working fine as stand-alone, using
http://localhost and http://localhost:8080 respectively.
2) Copied mod_jk2-2.0.43.dll to [Apache Home]/modules.
3) Added "LoadModule jk2_module modules/mod_jk2-2.0.43.dll" to [Apache
Home]/conf/httpd.conf.
4) Confirmed existance of [Tomcat Home]/conf/jk2.properties. This reads...
## THIS FILE MAY BE OVERRIDEN AT RUNTIME. MAKE SURE TOMCAT IS STOPED
## WHEN YOU EDIT THE FILE.
## COMMENTS WILL BE _LOST_
## DOCUMENTATION OF THE FORMAT IN JkMain javadoc.
# Set the desired handler list
# handler.list=apr,request,channelJni
#
# Override the default port for the socketChannel
# channelSocket.port=8019
# Default:
# channelUnix.file=${jkHome}/work/jk2.socket
# Just to check if the the config is working
# shm.file=${jkHome}/work/jk2.shm
# In order to enable jni use any channelJni directive
# channelJni.disabled = 0
# And one of the following directives:
# apr.jniModeSo=/opt/apache2/modules/mod_jk2.so
# If set to inprocess the mod_jk2 will Register natives itself
# This will enable the starting of the Tomcat from mod_jk2
# apr.jniModeSo=inprocess
>>>NOTE: I realise all lines are commented out, but I wasn't concerned as
the apache.org minimum configuration example was also. This read...
Minimum configuration is the simplest one to make the JK2 working. The used
channel will be socket, and lot of options are used by default. Both the
Tomcat and web server are on the same computer.
jk2.properties:
# The default port is 8009 but you can use another one
# channelSocket.port=8019
5) Created [Apache Home]/conf/workers2.properties (copied form apache.org
minimum configuration example). This reads...
# Define the communication channel
[channel.socket:localhost:8009]
info=Ajp13 forwarding over socket
tomcatId=localhost:8009
# Map the Tomcat examples webapp to the Web server uri space
[uri:/examples/*]
info=Map the whole webapp
>>>NOTE: At no time did I edit [Tomcat Home]/conf/server.xml.
6) Started Tomcat, waited.
7) Started Apache.
8) Attempted to browse JSP/Servlet examples without the ":8080", but got the
following error message...
Internal Server Error
The server encountered an internal error or misconfiguration and was unable
to complete your request.
Please contact the server administrator, [EMAIL PROTECTED] and inform them of
