Hahah, similar reasoning wth my symlink question...shouldn't matter,
but...

Hi,
It might not, but it's always a question, because it's part of the KISS
principle. The simpler the environment, the easier it is for the OP to
test and for others to reproduce the OP's test results. The less moving
pieces, the less chance for error.

Interesting question...how does that impact classloading?

Hi,
Does it happen without the connectors/Apache in front?

Subject: Re: MySQL driver randomly not found?
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 ''.
