I would like to know an effective and structured way to read the Ticket Dispatch Files that are sent to the Banks. I have already found some libraries that generate these files, but none that read those files.
If there is at least one simple library that already contains the logical structure of CNAB, I could continue.
Being more specific, I need to read the files that follow this Itaú layout ( link ) and of Bradesco ( link )
I'm starting to get to know the powerful java library, but it's hard to understand which objects or transfer objects I should use if there is no easy way to do this and if I do the reading myself.
