File to file basics - spring-batch

Question

Being new to Spring Batch, I wanted to begin with something simple....Reading a csv file and writing the same objects(records) to another one. Simple, isn't it ? But I was unable to find a working sample. After some time of research, I found some things which almost work....The file I want to write to is allways empty. Is it because I use a ressourcelesstransactionmanager ? Do I need to declare some optional property somewhere to flush the thing on my hard drive ?
By the way, I find the documentation on the subject very light and confusing, for a beginner. Maybe it's because one must earn spring Batch...
Here's the evil but very simple code that's driving me crazy.
TIA.

Answer 1

Sorry guys.
My mistake. I was getting confused with delimiters...The lack of properly configured log4j wasn't helping either.
I put the working configuration here.
