Java Database Connectivity (JDBC)

hi all

actually my code is..am using mysql..

Iterator itr = alist.iterator();

*while(itr.hasNext()){*

Exdo exdo = itr.next();

pstmt.setInt(1,exdo.getNo());
pstmt.setString(2,exdo.getName());

pstmt.executeUpdate();
*}*


this set of code is very slow when the alist size is high.. how do i change it to batch insert..
