Java Security

Hello all,

I have a problem loading "pkcs12" format keystore into the Keystore object, following is the code

---code------

InputStream is = new FileInputStream("c:/keystore/my_keystore");
KeyStore ks = KeyStore.getInstance("PKCS12");
System.out.println("KeyStore instance created.....");
ks.load(is,"password".toCharArray());
System.out.println("KeyStore loaded.....");
is.close();

--------------------------------
At runtime i am getting the following Exception

-----Error----------------------

KeyStore instance created.....
java.io.IOException: toDerInputStream rejects tag type 2
Exception in thread "main" java.lang.NullPointerException

--------------------------------

I have no clue on why this exception is thrown even after the keystore name, keystore file path and keystore passward being correct.

Any help in this regard will be appreciated.

I am running out of time, somebody please send me a reply on this topic as early as possible

Thanks in advance
