Java Programming

Hi
I have a encrypt, decrypt program, which does not work in IBM JDK

the code is as below, it gives PBEWithMD5AndDES does not exist kind of error when running with IBM JDK

{
	Cipher ecipher;
	Cipher dcipher;

	// 8-byte Salt
	byte[] salt = { (byte) 0xA9, (byte) 0x9B, (byte) 0xC8, (byte) 0x32,

	// Iteration count
	int iterationCount = 19;

	public MapsPasswordUtil(String passPhrase)
	{

			SecretKey key = SecretKeyFactory.getInstance("PBEWithMD5AndDES")

			AlgorithmParameterSpec paramSpec = new PBEParameterSpec(salt,

			ecipher.init(Cipher.ENCRYPT_MODE, key, paramSpec);

	}

	public String encrypt(String str)
	{
