ClassNotFoundException org/springframework/batch/item/file/mapping/FieldSet

[hailspring]

I am trying to load my simple-job-launcher-context.xml and getting following error:

org/springframework/batch/item/file/mapping/FieldSet is in transform package though. I am using 2.1.2 - and never got this issue before, any guess?

Dont worry about this... there was a conflict in different versions!

Hello,

I have the same issue now. I am trying to use AggregateItemFieldSetMapper class. In this class there is an import line :
import org.springframework.batch.item.file.mapping.FieldS et;
And I get the exception because my FieldSet is in the transform package. So what should I do?

Thanks,
Asal

Hello,
FieldSet has been removed from new spring batch 2.1.8. Instead use LineAggregator. It will solve purpose. See the Example of spring batch samples. they have used LineAggregator.

Thanks,
Sanjaya
