Hi Ashish,

till now, I was not aware of JSR 172. I have some doubts whether 
the combination of JSR 63 and JSR 101 is a good starting point 
for CLDC configurations, and I am not a big fan of transparent 
RPC (or JINI). Actually, I cannot imagine how transparent 
serialization will work without reflection. I tried to Join JSR 
173 (streaming XML), and I hope this JSR will produce an XML API 
better suitable for J2ME than JSR 63.

Personally, I would be more interested in a CLDC based profile 
that puts a subset of the Servlet API on top of CLDC; I think 
there would be many applications in small devices that do not 
have a screen but are attached to a network (routers, ...?) (so 
if France Telecom is going to initiate a corresponding JSR, 
please don't forget to invite me ;-).

Best,
Stefan
