I would recommend not using the admin console to define datasources.
There have been messages on this list for a while indicating the admin
console webapp doesn't always persist the config to the disk. Instead,
configure it in the context.xml file if at all possible.

Hi,
Need some help in using Oracle Database connection pool in jakarta-tomcat-5.0.28
Problem Description:
I created a JNDI(Name is jdbc/TestOracle ) for Oracle using Tomcat Admin console Example --TomcatServer->Service->Host->Context(TestProject)->Resources->DataSources using oracle.jdbc.driver.OracleDriver driver
In my web application I created a connection using above JNDI name.
private static final String JNDI_POOL="jdbc/TestOracle ";
Context oracleObjCtx = new InitialContext();
DataSource ds=null;
try {
ds = (DataSource) oracleObjCtx.lookup(JNDI_POOL);
} catch (Exception ne) {
oracleObjCtx = (Context)oracleObjCtx.lookup("java:comp/env");
ds = (DataSource) oracleObjCtx.lookup(JNDI_POOL);
}
conn = (Connection)ds.getConnection();
Above code is working fine in Window environment and it 's throwing exception in Linux while creating a DataSource
Error Message is
Name jdbc is not bound in this Context
