read an xls file using hashmap

If I want to read the data from oracle table using hashmap then i can read it like this......... 

String sql = "select * from DPY_VW_REP_DELIVERY_DTLS where weighed_date between ? and ?";
Object[] queryParams = new Object[] {dateFrom, dateTo};
List rsList = this.getJdbcTemplate().queryForList(sql, queryParams);
Iterator it = rsList.iterator();
while(it.hasNext())
{
    try
    {
        LinkedHashMap map = (LinkedHashMap) it.next();
        String[] strData = new String[14];
        strData[0] = map.get("WEIGHED_DATE_AS_CHAR").toString();
        strData[1] = map.get("WEIGHED_DAY_SLNO").toString();
        strData[2] = map.get("PARTY_NAME").toString();
        strData[3] = map.get("PARTY_ADDRESS1").toString();
        strData[4] = map.get("PARTY_ADDRESS2").toString();
        strData[5] = map.get("VEHICLE_NO").toString();
    }
}

but if I want to read an xls file containing same data using hashmap how can i do it....

Not sure what you mean by 'using hashmap'. JdbcTemplate.queryForList returns results mapped to a List of HashMaps.

It maybe easier to read excel files using Apache POI or similar tools. Alternatively, if using a spreadsheet as a database, you can use JDBC-ODBC bridge. Then you can execute your SQL query. Here is an example for this approach.
