"Unable to open config file" Error when starting tomcat

Question

hi all,
Here is the output from two of the log files when I start tomcat4 on my linux box. I have configured the mod_jk on the tomcat side.
From the output of the second log file, it seems that the ajp13 worker I defined was started successfully. What I don't understand is the following:
1) In catalina.out, where des the line 'Unable to open config file' come from? Which config file?
2) Tomcat4 is supposed to generate a mod_jk.conf automatically, but I don't see any file generated in 'conf/auto/'.
Content of 'catalina.out'
Unable to open config file
Starting service Tomcat-Standalone
Apache Tomcat/4.0.4

Answer 1

I have all those files too.
I think the 'config file' mentioned in the error log is the mod_jk.conf.
On Jason Hunter's tomcat4 guide, it says don't use the tomcat4 RPM to installed. What is the difference bettween the RPM version and the tar.gz version? The only difference I can think of is that in the RPM version, the conf directory is in the 'etc/tomcat4/conf'. Could it be the reason that tomcat4 cannot read the config file? But it has no problem reading the server.xml though.
