Runtime exceptions while trying to DES encryption

Question

Hi,
I am quite new to Java and I am trying the following Encryption/decryption logic using DES Encryption. It works fine on my machine which has JDK 1.4 version and JCE 1.2.2
CODE SAMPLE:-
import java.io.UnsupportedEncodingException;
import java.security.spec.AlgorithmParameterSpec;
import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.IllegalBlockSizeException;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.PBEKeySpec;
import javax.crypto.spec.PBEParameterSpec;
public class DesEncrypter {
Cipher ecipher;
Cipher dcipher;
// 8-byte Salt
byte[] salt = {
(byte)0xA9, (byte)0x9B, (byte)0xC8, (byte)0x32,
(byte)0x56, (byte)0x35, (byte)0xE3, (byte)0x03
// Iteration count
int iterationCount = 19;
DesEncrypter(String passPhrase) {
try {
// Create the key
KeySpec keySpec = new PBEKeySpec(passPhrase.toCharArray(), salt, iterationCount);
SecretKey key = SecretKeyFactory.getInstance(
"PBEWithMD5AndDES").generateSecret(keySpec);
ecipher = Cipher.getInstance(key.getAlgorithm());
dcipher = Cipher.getInstance(key.getAlgorithm());
// Prepare the parameter to the ciphers
AlgorithmParameterSpec paramSpec = new PBEParameterSpec(salt, iterationCount);
// Create the ciphers
ecipher.init(Cipher.ENCRYPT_MODE, key, paramSpec);
dcipher.init(Cipher.DECRYPT_MODE, key, paramSpec);
} catch (java.security.InvalidAlgorithmParameterException e) {
} catch (java.security.spec.InvalidKeySpecException e) {
} catch (javax.crypto.NoSuchPaddingException e) {
} catch (java.security.NoSuchAlgorithmException e) {
} catch (java.security.InvalidKeyException e) {
public String encrypt(String str) {
try {
// Encode the string into bytes using utf-8
byte[] utf8 = str.getBytes("UTF8");
// Encrypt
byte[] enc = ecipher.doFinal(utf8);
// Encode bytes to base64 to get a string
return new sun.misc.BASE64Encoder().encode(enc);
} catch (javax.crypto.BadPaddingException e) {
} catch (IllegalBlockSizeException e) {
} catch (UnsupportedEncodingException e) {
} catch (java.io.IOException e) {
return null;
public String decrypt(String str) {
try {
// Decode base64 to get bytes
byte[] dec = new sun.misc.BASE64Decoder().decodeBuffer(str);
// Decrypt
byte[] utf8 = dcipher.doFinal(dec);
// Decode using utf-8
return new String(utf8, "UTF8");
} catch (javax.crypto.BadPaddingException e) {
} catch (IllegalBlockSizeException e) {
} catch (UnsupportedEncodingException e) {
} catch (java.io.IOException e) {
return null;
public static void main(String args[])
     try {
// Create encrypter/decrypter class
DesEncrypter encrypter = new DesEncrypter("My Pass Phrase!");
String origText="My text";
System.out.println("Original Text="+origText);
// Encrypt
String encrypted = encrypter.encrypt(origText);
System.out.println("Encrypted Text="+encrypted);
// Decrypt
String decrypted = encrypter.decrypt(encrypted);
System.out.println("Decrypted Text="+decrypted);
} catch (Exception e) {
However, when i try it on another machine with JDK 1.3 and JCE 1.2.2 I get the error message
Exception in thread "main" java.lang.NoSuchMethodError
at javax.crypto.SunJCE_b.<clinit>(DashoA6275)
at javax.crypto.SecretKeyFactory.getInstance(DashoA6275)
at DesEncrypter.<init>(DesEncrypter.java:31)
at DesEncrypter.main(DesEncrypter.java:93)
Just for the sake of inference, we have already tried the steps mentioned in

and
http://archives.java.sun.com/cgi-bin/wa?A2=ind0103&L=java-security&F=&S=&P=14826
But the problem is ever persistent. Any help in this regards would be greatly appreciated.

Hello Praveen,
   This is just a Vanilla installation of the Portal and KMC. we are on EP 6 SP14. I try opening the KMContent and I get this big page of exceptions.
I am not able to figure out what and when was the final deployment..
Please suggest me if you have any solution in mind.
