I believe you are asking how to use the Connection Pool resource you successfully created in the admin console inside of a JSP or Java Class.
Hopefully you are already familiar with JDBC. Below is some very simple sample code. The datasource stringname will be the jndi name you provided in the admin console (ie. jdbc/mysql, jdbc/oracle, jdbc/whatever) appened to java:comp/env. Once you have the DataSource context, you create a connection. Then its just typical JDBC.
InitialContext ctx = null;
String dsName1 = "java:comp/env/jdbc/YOURDB";
DataSource ds1 = null;
Connection conn1 = null;
try {
ctx = new InitialContext();
ds1 = (DataSource)ctx.lookup(dsName1);
Connection conn1 = ds1.getConnection();
// use conn1 to do some database work --
// Create a statement, execute query ...
conn1.close();
conn1 = null;
} catch(Exception e) {
e.printStackTrace(System.out);
finally {
if (conn1 != null) {
try {
conn1.close();
} catch (Exception e) {
// ignore
}
