Matt,
If you don't find anything suggestive in the logs, try running with a
debugger and put a breakpoint
on the first statement in the contextInitialized method in your
AppListener to try to track down
why it's dying (i.e., what's causing SEVERE: Error listenerStart).
Then start steppting through.
You should be able to determine what the application listenters are
(there may be more than one) by
going to WEB-INF\web.xml and looking for the declarations <listener-
class>path.to.class</listener-class>.

Thanks - it was the first - I just had the files in the WEB-INF
directory - not in the lib
Is there some method for finding errors / logs? Right now, I'm trying
to get an application running, and I'm just guessing. For example, my
catalina.log file says
INFO: The listener "org.alfresco.web.app.ContextListener" is already
configured for this context. The duplicate definition has been
ignored.
Jul 24, 2008 3:46:11 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Jul 24, 2008 3:46:11 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/alfresco] startup failed due to previous errors
Where can I go to find out what's causing this?

This isn't a JDBC error as much as it's a taglib error. You are
trying
to use JSTL taglibs in your web application and tomcat can't find the
libraries that contain the taglib. Things to check:
1. standard.jar and jstl.jar are in the webapp's WEB-INF/lib
directory
-- at least for jstl 1.1. I believe jstl 1.2 consolidated things
into
one jar file.
2. The webapp's docBase is not the same as the <Host ...> element's
appBase attribute in server.xml. This has already bitten one
person on
the list today.

Sorry - I've been slogging through this...
Anyway, I'm trying to get an application working, but all of their
documentation talks about is tomcat5.5 and I've got tomcat6
I have gotten the latest Connector/J binary from MySQL and
installed in
into <tomcat>/lib but I would like to test it. So, I went to
http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html
and followed the instructions to set up a DBTest - but I get this

Here's the code that I'm running - are the taglibs incorrect?
