prepared statement not returning keys; driver used(mysql-connector-java-3.1.14-bin.jar)

getGeneratedKeys() method not returning resultset containing keys
after executing prepared statements in a batch

The code snippet is given below

String insertQuery = "INSERT INTO PRICE_LIST(ID,
SKU_CODE)VALUES(?,?)";

connection = springDataSource.getConnection();
preparedStatement = connection.prepareStatement(insertQuery);
for (int listPriceCount = 0; listPriceCount < listPrices.length;
listPriceCount++) {

preparedStatement.setInt(1, listPrices[listPriceCount]
.getID());
preparedStatement.setInt)2, listPrices[listPriceCount]
.getName());

preparedStatement.addBatch();
}

preparedStatement.executeBatch();

keySet = preparedStatement.getGeneratedKeys();

for (int listPriceCount = 0; keySet.next(); listPriceCount++) {
int key = keySet.getInt(1);
listPrices[listPriceCount].setId(key);
logger.debug("generated key: " + key);
}
