Am calling a java method from ESQl , am able to call the method but it gives the following exception after processing some statements

My Error :
:Java Exception calling CallStaticVoidMethodA.

:java.lang.NoClassDefFoundError:org/apache/commons/codec/binary/Base64.

My ESQl code :
DECLARE pkey CHARACTER 'xyxzh'
DECLARE inputmsg CHARACTER 'inputmsg'
CALL encrypt(inputmsg,pkey);

CREATE PROCEDURE encrypt(INOUT plainText CHARACTER,IN pkey CHARACTER )
LANGUAGE JAVA
EXTERNAL NAME "acces.AES.encrypt";

My java code :
pckge acces
class AES
public static void encrypt(String[] plainText, String key)
{
byte[] plainTextbytes;
try {

plainTextbytes = plainText[0].getBytes(characterEncoding);
byte[] keyBytes = getKeyBytes(key);
plainText[0] =Base64.encodeBase64String(encrypt(plainTextbytes,keyBytes, keyBytes));
}
}

public static byte[] encrypt(byte[] plainText, byte[] key, byte[]initialVector) {

Cipher cipher = Cipher.getInstance(cipherTransformation);
SecretKeySpec secretKeySpec = new SecretKeySpec(key,aesEncryptionAlgorithm);
IvParameterSpec ivParameterSpec = new IvParameterSpec(initialVector);
cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivParameterSpec);
plainText = cipher.doFinal(plainText);
return plainText;
}

I get an error noclassdeffounderror when it is returning the plainText...
I have included the common-codecs jar in my library, pasted in MQSI/jre17/lib and also in classpath..
what is the reason for this error ? how do i resolve it ?
