Hi,
I wanted to know when is the mapRow Method is been called.


Starts Here////

List userList=login.getLogindataList(bean.getUserName().trim(),encpassword);





public class ListRowMapper implements RowMapper
{
public Object mapRow(ResultSet rs, int rowNum) throws SQLException
{
Loginbean data = new Loginbean(rs.getInt(1),rs.getString(2));
return data;
}

ListRowMapper()
{
}


}


//////////////////////// Method //////////////

public List getLogindataList(String username,String password)
{
Object parms[]={username.toUpperCase(),password};
List noOfUsers = _jdbcTemplate.query("Select user_no,user_type from email.admin_user_master where upper(user_id) = ? and password = ?",parms, new ListRowMapper());
return noOfUsers;
}

The JdbcTemplate hides the normal regular plumbing code of jdbc. After the query is run a ResultSet is returned. In the JdbcTemplate, it will loop through the ResultSet and get a row, it will pass that row to the RowMapper class via the mapRow() method, along with which record number it is in the ResultSet.

That is all, it is called right after the query is run.
