Problem inputting a SecretKey object into a KeyStore

Question

i am having some problem storing my secretkey object in a key store, i keep getting the error shown below
cannot resolve symbol - class SecretKeyEntry.
the whole class is shown below. i have tried to import the SecretKeyEntry class but i still get an error. can anybody help.
import java.io.*;
import javax.crypto.*;
import javax.crypto.spec.*;
import java.security.*;
import java.security.KeyStore.*;
//import java.security.KeyStore.SecretKeyEntry;
import java.security.spec.*;
import java.util.*;
public class Encrypt {
public static void main(String args[]) {
File desFile = new File("Saving a text document as an image file.doc");
// Create data to encrypt
Map map = new TreeMap(System.getProperties());
int number = map.size();
try {
// Create Key
KeyGenerator kg = KeyGenerator.getInstance("DES");
SecretKey secretKey = kg.generateKey();
// key store code start
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
char[] password = {'f','r','a','n','k'};
System.out.println("my password" + password.toString());
ks.load(null, password);
// save my secret key
KeyStore.SecretKeyEntry skEntry = new KeyStore.SecretKeyEntry(mySecretKey);
ks.setEntry("secretKeyAlias", skEntry, password);
//keystore code end
// Create Cipher
Cipher desCipher =
Cipher.getInstance("DES/ECB/PKCS5Padding");
desCipher.init(Cipher.ENCRYPT_MODE, secretKey);
// Create stream
FileOutputStream fos = new FileOutputStream(desFile);
BufferedOutputStream bos = new BufferedOutputStream(fos);
CipherOutputStream cos = new CipherOutputStream(bos,
desCipher);
ObjectOutputStream oos = new ObjectOutputStream(cos);
// Write objects
oos.writeObject(map);
oos.writeInt(number);
oos.flush();
oos.close();
} catch (NoSuchPaddingException e) {
System.err.println("Padding problem: " + e);
} catch (NoSuchAlgorithmException e) {
System.err.println("Invalid algorithm: " + e);
} catch (InvalidKeyException e) {

} catch (IOException e) {
System.err.println("I/O Problem: " + e);
} catch (Exception e) {
System.err.println("All other exceptions" + e);
} finally {
if (desFile.exists()) {
//desFile.delete();
}

You need to change your setEntry() line to this:ks.setEntry("secretKeyAlias", skEntry, new KeyStore.PasswordProtection(password));You also need to insure that you're running under 1.5 - this API didn't exist before that. If you're picking up a 1.4 JVM/libs, it would explain your compilation error.
