Your workers.properties should be on your webserver where apache is located. I typically place the workers.properties in the same directory where httpd.conf is located.
workers.properties is needed for mod_jk so it makes sense that it needs to be in the same machine where mod_jk and apache are installed. At least far as I know anyways. Sometimes apache has a difficult time finding it. I have used this line to tell apache where to find the workers.properties. You might try including a line like this in your apache configuration file: <IfModule mod_jk.c> JkSet config.file /etc/apache2/conf/workers.properties Include /etc/apache2/conf/mod_jk2.conf </IfModule> If anyone else has anything to add to this or correct me on, please feel free because I am still learning to, but then again who isn't?? I hope that helps. -----Original Message----- From: Hari Om [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 23, 2004 8:56 AM To: [EMAIL PROTECTED] Cc: Randall Svancara Subject: RE: Apache+Tomcat + MOD_JK on different machine Thanks Randall for your reply... appreciate that! My MOD_JK.CONF file is AUTOGENERATED on my AppServer. I start my App Server FIRST which AUTOGENERATES "mod_jk.conf" file. So, how can I reference this file on my HTTPD.CONF ("Include conf/mod_jk.conf") - which is indeed located on a different machine? Where should I place my workers.properties? should it be on App Server or Web Server? Should I first start App Server or Web Server or it does'nt matter? In my HTTPD.CONF I have different mount points (example 'abc') so when I type http://IPADDRESS/abc it shows "HTTP 400 Bad Request" on my browser Howevere, when I type http://IPADDRESS/lmn it shows "HTTP 404 Page Not Found" (Note: lmn is not added a JKMount in my Httpd.conf) My MOD_JK.log file shows it added all the JKMounts. My ACCESS_LOG file shows: [23/Mar/2004:08:44:05 -0700] "GET /abc HTTP/1.1" 400 0 [23/Mar/2004:08:50:24 -0700] "GET /lmn HTTP/1.1" 404 301 My ERROR_LOG file shows: [Tue Mar 23 08:41:46 2004] [notice] Apache/2.0.47 (Unix) mod_jk/1.2.2 configured -- resuming normal operations Any related information on above is appreciated.
