Newbie Simple app issue most likely related to user coding error

Question

I'm fairly new to the Cyberflex infrastructure and most likely the issue is with my CODE. Basically, I wrote a simple java cardlet without much error checking to try to retrieve a stored object on the card such as a userId. What I think I'm missing or don't understand is how to capture the incoming APDU and respond to it within the process method.
Error:
I keep getting a [6C 01] status word return code? Is this a valid Status Word?
Environment Setup:
Compiler: jdk1.3.1
Axalto SDK: 4.4
Card: Cyberflex e-gate 32k (not personalized and it has no pin assigned to it)
OS: Windows 2K
Any help will be greatly appreciated.
Thank you in advance,
Alfredo
Here is the code:

Answer 1

An oversight on my part that was discovered by a second set of eyes.
1. Invalid expected return size was specified.
final static short MAX_USER_ID_SIZE = ( short )10;
needed to be changed to
final static short MAX_USER_ID_SIZE = ( short )0xA;
2. The calling apdu needed to be modified to
B0 02 00 00 0A
Well I hope this helps others as well
