does that path and file exist?
The 'httpd.conf' file for appache 2.2 was calling for the mod_jk.conf file
The call is a the end of the file and once deleted from the httpd.conf file Mac os x 10.5 web services resumed.
I think the file file was installled in Filemaker Server Advanced 9 but is not required in Filemaker Server Advanced 10.
Unistalling filemaker did not remove the call for the file, as it did not adjust the httpd.conf file.
Once this was done manually all processes went back to normal .... so far
Thanks for your help
