Subject: Questions about Java channel access client

Dear all,
We need to develop the facility status web UI using Java for CSNS, the web UI will get data from live PVs, and we are now considering which Java channel access client library to use.  

On the EPICS official website, the following ones are mentioned.

CAJ: Pure Java Channel Access Client (SF)
JCA: Channel Access client for Java using JNI (SF) (original at APS/BCDA)
CA: Another pure Java Channel Access client implementation (Github)
JCAE: Java Channel Access Extensions library (Github)

So my questions are as follows:
1. Are JCA and CAJ already obsolete? I ask because most documentations for them do not seem to be available anymore. Also, they are not moved to github like other active maintained projects.
2. Are CA and JCAE the replacement or improvement of JCA/CAJ?
3. For CA and JCAE, which one will you recommend?


Thanks,
Lin
