http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6420 Loadbalancer mod_jk from 4.02 not working with TC 3.3 Summary: Loadbalancer mod_jk from 4.02 not working with TC 3.3 Product: Tomcat 4 Version: 4.0.2 Final Platform: Sun OS/Version: Solaris Status: NEW Severity: Critical Priority: Other Component: JK/AJP Connector AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] exchanging mod_jk.so from TC 3.3 version to 4.0.2 connectors package version -> loadbalanced ajp13 workers do not work anymore Hi, I just ran into a problem with the loadbalancing stuff. I built mod_jk.so from the 4.0.2 connector package and replaced my mod_jk.so (TC3.3 Version) with this one in apache/libexec (1.3.19). By just changing a link back and forth between the two versions, I tested our TC3.3 based application against the two versions of mod_jk. If this is not enough and I am missing something, please let me know. Otherwise exactly the same setup All works perfectly with the new mod_jk when I use normal ajp13 workers (one webapp), but fails when I use a loadbalancing worker pointing to another webapp on a different Tomcat instance. Note, We use the loadbalancer just for switching tomcats. Only one instance of the two loadbalanced Tomcats is active most of the time. (by changing the lbvalue) Here the relevant parts of my mod_jk.log.
