Is Oracle driver (classes111.zip) visible to Tomcat.
I had to modify (in Linux) catalina.sh script to add driver's path to
the internal
CLASSPATH used by catalina.

Hello
Im having problems creating a DataSource in a StandAlone Tomcat 4.0.1
with Windows XP. The InitialContext find the DataSource but it cames
null
This is the Code:
%
InitialContext ctxinit = new InitialContext();
%
%= ctxinit.lookup(java:/comp/env/jdbc/testDB) % NULL
You get EnabledDataSource instance above so you have to cast.
May it's be better like this:
% DataSource ds = (DataSource)
ctxinit.lookup(java:/comp/env/jdbc/testDB) %
%= ds %
Also all examples doing this way:
Context ctx = new InitialContext();
Context envCtx = (Context)ctx.lookup(java:comp/env);
ds = (DataSource)envCtx.lookup(jdbc/testDB);
Try that just in case.
So your case must work!!
Though I don't advise you to use EnabledDataSource (Tyrex stuff) for
production - it doesn't provide
connection pool.
Use commons/dbcp.
I tested it - it works fine (besides Tomcat 4.0.4-b1 - nothing work
there).
In the web application deployment descriptor (web.xml) i have this code:
resource-ref
descriptionResource reference to a factory for java.sql.Connection
instances that may be used for talking to a particular database that is
configured in the server.xml file./description
res-ref-namejdbc/testDB/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
In the server.xml file:
Context path=/test docBase=test/ debug=1 privileged=true
reloadable=true useNaming=true
Resource name=jdbc/testDB auth=Container
type=javax.sql.DataSource description=Default Database for
Applications /

When i use debug level 1 in the context the logs seems normal:
