connection pool coding

In any case, this has Weblogic 8.1 specific connection pooling stuff:

http://edocs.bea.com/wls/docs81/jdbc/programming.html

>>JDBC API to communicate with the driver.

could you give me a sample api code for that

Standard JDBC is simple:

Class.forName ( driverClassName ) ;
Connection con = DriverManager.getConnection () ;
Statement s = con.createStatement () ;
ResultSet rs = s.executeQuery ( "your SQL query" ) ;

while ( rs.next () )
{
  // get the data using rs.getString ( "column name" ) ;
}

tht code i know already.

if any specific connection pool coding apart from that

If the driver handles connection-pooling - no.

>>Class.forName ( driverClassName ) ;

what i could specify in driver class name if my database is db2

I think its "COM.ibm.db2.jdbc.app.DB2Driver"
