Around here we put the LD_LIBRARY_PATH in the envvars file in the apache httpd bin directory. That way it is loaded by the apachectl script - and is more or less immune to the environment getting messed with (usually by someone messing with shell configuration files).
This is rather well documented in the apache httpd documentation as well. It works quite nicely. > Please add the lib directory to your LD_LIBRARY_PATH or do an equivalent of > this (ldconfig)." Opinion: Thank you to all of you who contribute to this project, it is simply wonderfull. I am glad to finally break the chain of java servlet engines using so much .... Sorry, I'll stop there. [Axis2C] is an amazing product and I hope that it carries on for many years. -John. First post to list.
