Scott,
I feel your pain -- I just finished sorting out that whole thing
myself. One thing I'd definitely recommend doing is installing the
admin tool for tomcat 5 and using it to change something trivial in
your server.xml file. When it gets done making the change it strips
out all the comments as a side effect and makes the file *much*
cleaner and, in my opinion, more readable. As for your question:
if the resource is to be used for multiple applications, you could put
it in the server.xml... if not (and I'm going to presume that's the
case for you -- let me know if not) then you're much better off using
your application-specific WEB-INF\web.xml and META-INF\context.xml
files like so:
your application docbase\META-INF\context.xml would look something like:
Context path=/Foo
docBase=C:/Foo
debug=1 reloadable=true
Resource
auth=Container
name=jdbc/aNameForYourDBresource
type=javax.sql.DataSource
password=Foo
driverClassName=oracle.jdbc.driver.OracleDriver
maxIdle=3
maxWait=5000
username=Foo
url=jdbc:oracle:thin:@Foo:1521:Foo
maxActive=15/
WatchedResourceWEB-INF/web.xml/WatchedResource
WatchedResourceMETA-INF/context.xml/WatchedResource
/Context
and your your application docbaseWEB-INF\web.xml would then
reference the resource defined in the context above (the res-ref-name
should match the resource name)
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app

It's helpful to think of the individual application context.xml files
being 'included' as context entries in the server.xml file (almost
like an @include, except implicit).
Hope that helps! Let me know if I can clarify anything.
Cheers,
Patrick Thomas
(PS - remember to install the jakarta commons and pooling jars
mentioned in the dbcp documentation.)

Hi.
Take a look at this for where to put Context elements:

Hello,
I am following the information here to add DBCP to my application.

I am reading to add the Context path=/DBTest ... from the above docs. The
instructions say to .
Configure the JNDI DataSource in Tomcat by adding a declaration for your
resource to $CATALINA_HOME/conf/server.xml.
Add this in between the /Context tag of the examples context and the
/Host tag closing the localhost definition.
So cool, I opened up the server.xml, but do not see any existing context or
host tags in it. Here is my server.xml file. Does anyone know where I put
the Context for the DBCP stuff? Thanks,
