I followed this how-to to set up mod_jk on my server, but run into some issues - http://www.howtoforge.com/apache2_tomcat5_mod_jk_p2 My platform OpenSuse 10.2 Apache 2.2 Tomcat 6.0.16 Jakarta-Tomcat Connector 1.2.26 ISPConfig 2.2.23 Problems 1) This line added to server.xml is creating a classnotfound exception when starting up tomcat. I see the error in my catalina.out log; and this exception causes Tomcat to not start. When the line in server.xml is commented out, I'm able to start Tomcat, and the auto config file is generated. How do I retrieve/install the missing class? I've already tried re-downloading and re-unpacking Tomcat and the connector; but the error is still there. Line in server.xml Error in catalina.out 2) After finishing all configurations and restarting apache, the following error is thrown by Apache. I'm no longer able to access www.example.com, though I was able to before. [I've substituted my domain name with www.example.com.] This error is seen when Apache starts/stops. Once I remove the include in httpd.conf for mod_jk.conf (and the corresponding JkOptions, etc.), I'm able to access www.example.com again. This is the content of my auto generated mod_jk.conf file. I've checked that the paths are correct. Any ideas where I went wrong? Is this issue related to the 1st problem about the StoreConfigLifecycleListener class?
