discuss namespace in java code

[Ma, Sheng-Chen (Aven)]

Hi all:
I noticed that our trafodion namespace is org.trafodion.sql or 
org.trafodion.dtm.
Since trafodion been one of apache project ,in my view is we should use 
org.apache.trafodion.xxx, but there is a huge change, so I send this email to 
discuss this. If it's ok to change, I will do this job.

Thanks
Aven
