I did provide the correct answers, or rather, repeat them.

This may be true, but it *wasn't* the question. Local/Remote isn't
mentioned in the question anywhere.

Just for my own amusement, here is the original question in full:
>>>>> starts here >>>>>
1) Which is faster JNDI Based Connection pool / ordinary JDBC based
connection / close ?
2) In JNDI / context based Connection pool for the code given below
InitialContext ic = new InitialContext();
DataSource ODS
=(javax.sql.DataSource)ic.lookup("java:comp/env/jdbc/MYSCEMA");
Connection conn = ODS.getConnection()
// Insert /Update /Delete/...
conn.close() --> What does this code do ? (return connection to pool
or close the connection )
Googled /yahooed but non correct answers ....
<<<<< ends here <<<<<
Prizes for anyone who can spot the references to India or Ithaca within.
I think the real question is this: what is the result of this
calculation: ( any large prime number ) divided by zero?
The point I was so laboriously making, is that it's easy to post
irrelevant nonsense scraped from the depths of the internet. But it's
not helpful, so please stop it.
