Mod_jk setup problems
Hi, I am running Tomcat5.5.9 and JDK1.5.0_04 with a Apache 1.3 webserver on FreeBSD 5.3. I can't seem to get anything to successfully pass though the mod_jk connector to the webapp. My mod_jk.conf , workers.properties are as follows. $ less mod_jk.conf # JkWorkersFile /usr/local/etc/apache/workers.properties JkLogFile /var/log/jk.log JkLogLevel debug ServerName localhost # Sample JkMounts.

Since they don't overlap, Apache will not know anything about static files (html, css, etc.) that live in $CATALINA_HOME/webapps. You can use Directory and Alias directives in Apache to set up access and map the directory into a URI space that Apache knows about. With later versions of mod_jk, you can use JkAutoAlias to map directories for you. From the documentation at http://jakarta.apache.org/tomcat/connectors-doc/config/apache.html JkAutoAlias /opt/tomcat/webapps Then you can use JkMount to map certain requests (*.jsp, /*/servlet/*). JkMount /jsp-examples/*.jsp worker1 The value of JkAutoAlias appears to be prepended to the JkMount directive to find the physical location. I've not used JkAutoAlias, but this appears to be a nice alternative to Directory and Alias directives in httpd.conf. In short: 1. Add JkShmFile to httpd.conf 2. Remove lbfactor from workers.properties 3. Change the spelling of recycle 4. Use JkAutoAlias or Directory / Alias directives to put the appropriate directories within Apache's document and URI space.

I have noticed that 8080 is not responding any more if I just try to hit TC directly so I think, correct me if I'm wrong... this won't work even if setup correctly, until I fix that.

Re: Mod_jk setup problems
Glad I was able to help a little bit. In my experience (Linux,Solaris,Win/2K), 8080 should always work if you have the Connector configured. If you can't get to http://localhost:8080/jsp-examples/ running, then there is something else amiss. In your httpd.conf file, I still didn't see something like the following: JkShmFile /var/log/memory.shm This wasn't necessary in 1.2.6 and may not be necessary in 1.2.14, but according to the documentation it's used on UNIX platforms. In workers.properties lbfactor is used to set the relative weight of a worker when you're doing load balancing. Since you're not doing load balancing, letting it default to 1 should be fine. You have two JkMounts for docstore. I'm thinking that only: JkMount /docstore/* worker1 is necessary. If the entire web application (including static files) lives in $CATALINA_HOME/webapps, then the Apache process will need access to those directories and files. Finally, a long time ago the order of startup was important. I think it was Tomcat first, then Apache. It's been a while, and right now I'm on the Windows side of this machine so I can't check. The order of startup issue went away with Apache 2.0.x, but it may still be an issue with your environment (Apache 1.3.x). I would be interested in seeing your error logs from mod_jk as well as seeing what catalina.out has in it when you try to get to a web application via port 8080. Hope this gives you some avenues to explore. /mde/ __ Do You Yahoo!? Tired of spam? Yahoo!
