Thanks for the tips.
Actually, I added another context (context) to the tomcat_home
\conf\server.xml, which specifies the database parameters and I'm good to go.
Didn't help that I was also working with the wrong server.xml file.

Please respond to
Tomcat Users List
If you want to create a default database for all web-apps ( i don´t
known if you want the same database´s user also ), you should add a JNDI
datasource in GlobalNamingResources, try to use tomcat´s manager. Remeber,
you must put your JDBC driver in common/lib also, because tomcat need it to
create the datasource, but in your case, maybe you did try a simple
connection and forgot to put JDBC driver in shared/lib or WEB-INF/lib.

Assunto: Multiple webapps talking to same DB
Version of Tomcat - 4.1.24
OS - WinXP (development workstation)
DB - MySQL 4.0.13
I currently have a single webapp (test1) that can connect to the database
and
perform DB operations just fine. This uses JSP, Servlets and JDBC.
What I want to do is have other webapps connect to the same database. Here
is
what I did:
1. I copied my existing webapp, tomcat_home\webapps\test1 and created
tomcat_home\webapps\test2.
2. I restarted tomcat and when invoking the test2 webapp, I get the
following
error: java.sql.SQLException: Cannot load JDBC driver class 'null'
This error happens when I call the getConnection() method on the
DataSource
object.
I believe I don't have the correct configuration in the server.xml for the
webapp, test2. I tried several different ways to try and get this to work,
but
those have
failed so far.
So, when making a straight copy of one webapp like I did above, what would
need
to change in the server.xml (in the MySQL section) to get this to work?
Or, would the culprit be some other configuration?
Thanks for any help on this,
Kevin
