Re: BigDecimalColumnInterpreter
Hi Guys,

I found something really interesting. If i run the utility then i also get
the errors related to readfields.
*Howerver, within the same eclipse project, the separate class which i have
been using in my setup for more than 2-3 weeks is working absolutely fine.
In a short while i could not figure out what's helping this class to run
successfully. I'll try to dig in.
*Here is the error message i received from utility:*
*2012-09-14 12:17:04,127 WARN  [main]
