Keystore java.io.IOException

Question

Hi all, when i try to generate a secretkey and store it in a keystore, but i get an io exception for some reason.
it says:
Exception in thread "main" java.security.KeyStoreException: java.io.IOException:
Error initialising store of key store.
i really don't know what i'm doing wrong, a little bit of help would be usefull
this is a piece of my code:
private static String FILENAME = "keystore.ks";
private void registerUserKey(char[] password) throws Exception{
          // Generate secret key for HMACRIPEMD160
          KeyGenerator kg = KeyGenerator.getInstance("HMACRIPEMD160");
          SecretKey sk = kg.generateKey();
          // Create a keystore and place the key in it
          // I use an UBER keystore, which is provided by Bouncycastle.
          KeyStore keyStore = KeyStore.getInstance("UBER");
          keyStore.load(null, null);
          String alias = "exampleKey";
          keyStore.setKeyEntry(alias, sk, password, null);
          FileOutputStream fos = new FileOutputStream(FILENAME);
          keyStore.store(fos, password);
          fos.close();
     }

Answer 1

my days of wandering forums of all kind have finally paid off.
seems like adding the specific classpath option solves my problems
so now i run and compile my files with this line
java -Xbootclasspath:c:\jdk1.2.2\jre\lib\ext\jce-jdk12-118.jar;c:\jdk1.2.2\jr
e\lib\rt.jar; myfilename
and it works fine.
if there is anybody who can tell me why it doesn't work when i change my classpath (and class), that would be hugely appreciated.
But at least now i can run my applications
