Message:

custom class Loader

Posted by Soumya Dutta on April 14, 2001 at 7:17 AM

Hi ,
I would also like to the answer to your question. I already have my classfile encrypted in some form and after decrypting, I have got the byte array which has the byte codes of the class file, but i am not able to make a Class object out of it. Please help.
Thanks in advance,
- Dutta.
