jsonItemWriter

What is passed to the jsonItemWriter? Reason I ask is, suppose I want to use the beanioreader use an itemprocessor to reformat that bean into another bean and have the jsonitemwriter write out the results. What am I returning from the itemprocessor?

org.jberet.support.io.JsonItemWriter, in fact, any ItemWriter, takes java.util.List<Object> as input. So in case of JsonItemWriter, any type that can be properly converted to JSON format by Jackson, which is the library used by jberet-support underneath. The data type class is either pretty simple to convert, or contain some JAXB or Jackson annotations to help the mapping. An example class:
