Batch Uploader

Hi,

I'm using SmartGWT EE version. My business requirement needs me to update records in a table of HSQL database (inbuilt-provided in SmartGWTEE) with the values uploaded through a CVS file.This is very similar to BatchUploader sample provided in showcase. As I'm very new to this I found it difficult to integrate BatchUploader in my project(which is similar to BuiltInDS sample). Could you please give me a reference/pointers to complete source code of BatchUploader or anything that suits my requirement.

Thanks,
Satish.
