Hi, Kind of a repost, I never heard anything back from the original post... I cannot get Apache and Tomcat to work together with servlets... static pages are fine, but I get an internal server error when I try to access one of the examples/servlets/ servlets. The error message from mod_jk.log is this: [jk_ajp12_worker.c (503)]: ajp12_handle_response, error reading header line What the heck is this? What did I do wrong? How do I fix it? If more info is needed, let me know what and Ill post it. Thanks! Bryan Summary installation log: On a Redhat 6.2 box: Apache 1.3.20 compiled with OpenSSL 0.9.6b and MM 1.1.3. Tomcat 3.2.2 Compiled and installed compiled and installed mod_jk.so added "include <path to tomcat conf>/mod_jk.conf-auto" to httpd.conf (did not change it) http & https check out fine tomcat checks out fine apache can serve static pages fine from tomcat no servlets work...
