Mine differs slightly, though I see you're obviously on a diff. version of
Tomcat than I am.
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
// Look up our data source
DataSource ds = (DataSource)
envCtx.lookup("jdbc/myoracle");
// Allocate and use a connection from the pool
Connection connection = ds.getConnection();

Hello:
I am in a bind.
I am getting:
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context at
org.apache.naming.NamingContext.lookup(NamingContext.java:770)
at org.apache.naming.NamingContext.lookup(NamingContext.java:153)

util.LoadDropdownListener.contextInitialized(LoadDropdownListener.java:78)
when I add:
<Resource name="jdbc/GFDataSource" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
connectionCachingEnabled="true"
maxActive="30"
maxIdle="2"
maxWait="1000"
username="GLP_S"
password="gideupstg"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@server:3333:SID"/>
to either server.xml (under <Server>), config/context.xml (under <Context>), or
in META-INF/context.xml.
Here's what these files look like when I place <Resource> in them:

Here is the offending code:
Context context = new InitialContext();
DataSource pds = null;
pds = (DataSource)context.lookup("jdbc/GFDataSource");
Connection conn = pds.getConnection();
context.close();
I have tried java:comp/env/jdbc/GFDataSource as well. I am using
ojdbc14dms.jar and dms.jar.
