Last thursday I asked for some help with the AJP connection error.
I am struggling with it and didn't get any respons, so if someone has some
idea's, please let me know (have a look at the message below).
Originaly error message:
--
When executing a servlet and the Jserv is in automatic mode (ApJServManual
=off) it writes the following error in the mod_jserv.log file:
[14/12/2000 16:07:11:361] (EMERGENCY) ajp12: can not connect to host
127.0.0.1:8
007
[14/12/2000 16:07:11:361] (EMERGENCY) ajp12: connection fail
[14/12/2000 16:07:11:361] (ERROR) an error returned handling request via
