Hi All,
You may recall I posted that I solved this problem some time ago...I
was trying to reference my JNDI pool in the init() method directly
and I was getting "Cannot create JDBC driver of class ''" errors. I
moved that out into the classes themselves and it was going so well.
But I have spotted that problem again in my logged. It may have been
there all along as my application continues to work, but I do not
like erroneous messages coming out in my logging - it makes me
nervous!
Check out the following logging taken just after I start TC 5.0.18.
My servlet that called this stuff does not have a load-on-startup but
it still decides to initalise TWICE. The odd thing about this from my
POV is that the first INIT is fine .. you can see that a
PoolableConnection gets created and the NavigationManager can get on
with its job. Now look at the second INIT which decides to not find a
PoolableConnection because of something to do with a null JDBC
driver.
Now I'm no rocket scientist but this strikes me as bizarre. And I
would just like to mention that there is nothing wrong at all with my
JNDI reference in the server.xml. I promise you that.
So on this assumption that it is not the server.xml (because my
application works and all my other pools work) why on earth am I
getting
1. 2 initialisations for a non load-on-startup servlet 2. Cannot
create JDBC driver of class '' when clearly the first init had no
problem!

Thanks! ADC
The most likely is that you have two webapps (one created from your
Context element - remember to put Context elements in a separate file
rather than in server.xml - and the other one because you have your
folder in webapps and its name doesn't match your context path).
