Exception "algorithm ARC4 is not available from Provider Cryptix "

Question

hi all
i am developing the application in which i am using two encryption/decryption algorithms one is "RC4" and second is "AES(256 bit key)".
1.first i am taking the credit card number from database which is in
the encrypted format using 'RC4".
2.After taking the Credit card number from database i am decrypting them using RC4.
3. After decrypting them i am encrypting them using "AES(256 bit key") and putting the paymentid and encrypted credit card number in HashMap.
For that i have written following classes
RC4EncMemory.java ( which is taking encrypted credit card number from database ,decrypting them using "RC4" and then encrypting them using "AES")

In the above programs i am getting the output as follows
output:-

after encryption of data
In while
paymantid >>> 3338169

decrypted original >>> null
In while
paymantid >>> 3338290
SecurityException in decrypt method: java.security.NoSuchAlgorithmException: algorithm ARC4 is not available from provider Cryptix
decrypted original >>> null
my program is able to decrypt the only first credit card numbers using RC4 and then encrypt it using AES(as shown in bold above) but it is not able decrypt the rest of the credit card number from the database using "RC4" and it is throwing above exception regarding the "RC4" algorithm .
can anybody tell me what is reason behind this exception? my guess is the we cann't use the two providers simultaneously.
please anybody help me

Answer 1

Hi Nith,
Previously I have changed the document dispostal time out to 1 year but the error still occurs.
Now I change the document inline size from 64 KB to 27 MB (estimated max document size) and see how the LCES behaves.
I suspect if document size is larger than document inline size then LCES will write to some temp file. After that, user does not process the task for a long time, e.g. 3 days. And during the 3 days, the unix system/ websphere auto clear the temp file. After 3 days when user accesses the task again, LCES will complain "document is not in sending server side any more" ....
I refer to : http://blogs.adobe.com/livecycle/2008/10/livecycle_tuning_knob_default.html
For the Document sweep interval, I think, it relates Watch Folder, not this error so I don't change it.
Regards,
Anh
