Connecting Apache 2.2 and Tomcat 5.5

[Bryan Douglas]

I successfully installed apache and tomcat, and the both work well alone. I want to connect apache and tomcat, however. I follow the directions at mod_jk connector docs, but neither the automatic config mode nor the manual settings mode worked. After making the changes, tomcat starts, but apache cannot. When I try to restart the apache service, it says "The requested operation has failed!" If I comment out the lines that I added to httpd.conf, the server starts perfectly.

Question: Is there a way I find out which line the error occured on while reading httpd.conf? There is no entry writtn to error.log in the logs directory. And that is the specified file in the httpd.conf file. Frown


Reference information:
Host System: Windows XP Pro
Apache: v2.2.3
Tomcat: v5.5.17

In order to try to get tomcat and apache to place nice together, first, I downloaded mod_jk.so from the tomcat homepage, and I copied it to the apache modules directory.

In the apache conf folder, I created a workers.properties file that contains:

workers.tomcat_home=C:/Program Files/Apache Software Foundation/Tomcat 5.5
workers.java_home=C:/Program Files/Java/jdk1.5.0_08
ps=/
worker.list=worker1
 
worker.default.port=8009
worker.default.host=localhost
worker.default.type=ajp13
worker.default.lbfactor=1

At the bottom of the apache httpd.conf file, I appended:

#
#
# Tomcat 5.5.17 connection settings
#
#
LoadModule jk_module C:/Program Files/Apache Software Foundation/Apache2.2/modules/mod_jk.so
# Where to find workers.properties
JkWorkersFile C:/Program Files/Apache Software Foundation/Apache2.2/conf/workers.properties
# Where to put jk logs
JkLogFile C:/Program Files/Apache Software Foundation/Apache2.2/logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"
# Send servlet for context / jsp-examples to worker named worker1
JkMount /jsp-examples worker1
# Send JSPs for context /jsp-examples/* to worker named worker1
JkMount /jsp-examples/*.jsp worker1

Hi Bryan,

I just got an identical setup working this evening...despite the absense of a single guide out on the net. You should not have to create or download and copy anything. TC5.5 and httpd 2.2 are supposed to play well together with AJP1.3. Maybe this will work for you as it did me:

Install httpd 2.2
Install tc 5.5
Uncomment (remove the # symbol) the following lines in httpd.conf

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so

Add at the bottom of httpd.conf

<Location /examples/>
   ProxyPass ajp://localhost:8009/examples/
</Location>

(where the url is a deployed tc webapp that would respond if the protocol was http and the port 8080)

Restart both services...and...

Presto!

I may have uncommented too many httpd.conf line but that can wait for later.

Let us know how you get on.
