Februar 2002 08:23 An: Tomcat Developers List Betreff: AW: Native Connector problems 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. I do not have the mod_jk.log here at home. Will send it in a couple of hours when I am in the office. What else would be required for debugging? 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) Thanks, Hans > -----Ursprungliche Nachricht----- > Von: Mike Anderson [mailto:[EMAIL PROTECTED]] > Gesendet: Mittwoch, 13.
