Just curious...Why are you using a symlink?
>>> [EMAIL PROTECTED] 10/14/04 9:59 AM >>>
Hello! I'm having an interesting problem wherein about 5-10% of the
time, for
no apparent reason whatsover, the MySQL driver just can not be found. I
have
a symlink to it in TOMCAT_DIR/common/lib. I just replaced the symlink
with a
copy of the actual library to see if that would make a difference, but
it
doesn't make sense that it would work 90-95% of the time and then fail
the
rest of the time if that were the problem.
The traceback I get is as follows:
// NOTE: replaced org.apache. with ''.
