check the logs earlier, if you havent moved the mysql-xxx.jar into
TC_HOME/lib, then tomcat can't create the connection pool, and the JDBC
name will not exist

The error hasn't actually changed from the one I posted originally. Is there
any way of changing Tomcat's logging to display more information? I know
there is a reference to a Ejb3Configuration.buildEntityManagerFactory but i
am not actually using EJB3's. I am just using the
EntityManagers/EntityManagerFactory that uses config from persistence.xml, a
file in which you can tell it what datasource to make your persistence unit
to use. I tell it to use "jdbc/workout_logger".
I guess I can try writing a simple Servlet that tries to get the context
using the example in Tomcat's docs. I just thought that in the end, all ways
call the same InitialContext.lookup method.

- I have copied the same stacktrace that I am getting. It's almost as if the
config changes haven't done anything. Just to make sure that it's loading
the files, I tried to start tomcat with a "broken" xml and it fails to
start, so I know that it's loading the right config files.

I check and my db user "user" has full access to the DB it's trying to
use.
Is it possible that I am missing a library or something in the classpath
of
tomcat? I already have the mysql connector library ( I had my DB
connections
working fine without datasources before, but I am trying to switch to
using
datasources).
Thanks again

hey, sorry about that. The actual string I have in my app is
"workout_logger"
I just tried to replace my strings for "my_jdbc_name" for the posting.
I
guess I forgot to rename the in the error.
other than that, do you see anything else wrong?

here is the name you specify

as you can see, somewhere you have configured the string
workout_logger,
and that one doesn't exist

Hi!
I have been reading how to setup datasources for Tomcat 6.0.18 in
http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html
and nothing I have done has allowed my web application to view the
datasource i have created.
Here are some snippets of my web.xml, and my server.xml
In the web.xml
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/my_jdbc_name</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
In server.xml
I have tried to place the following snip it anywhere I saw in the
docs
it
could belong to (ei, in the GlobalNamingResources, inside the Host
tag,
or
inside the Context tag in all possible locations (under
META-INF/context.xml, under
$CATALINA_BASE/conf/[engine]/[host]/[path].xml)
and I haven't been successful.
<Resource name="jdbc/my_jdbc_name" auth="Container"
type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="user" password="password"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/database_name?autoReconnect=true"/>
I am using Entity Managers to get my connections opened, here is the
snip
it
of my persistence.xml
<persistence-unit name="my_pu_name"
transaction-type="RESOURCE_LOCAL">
<non-jta-data-source>jdbc/my_jdbc_name</non-jta-data-source>
</persistence-unit>
Here is what I get in my tomcat logs:

Does anybody know what I am doing wrong? Is there any way to check
which
resources Tomcat makes avaiable? I am having a really hard time
understanding what I am doing wrong.
