How to enque and deque from CE7.2 with arfc2 JCo?

Hello, experts.

I'm testing enque and deque using ARFC2 of CE7.2.

ARFC2, JCo 3.0, looks like working differently from previous version

by logging off the connection user so I can't hold session data at ECC, like lock entry.

Is there any way to acheive this problem?

Thanks your time in advance.
