David,

Just tried your latest one for pooled datasource. It works for
executeQuery if using the connection with following call
c = ds.getConnection("SYSDBA", "masterkey");

However, if
ds.setUser("sysdba");
ds.setPassword("masterkey");
c = ds.getConnection();

It does not work if exucuteQuery using the above getConnection()
method.

Thank you for your efforts and help.
