Flat file to Bean conversion in java?

I have a CSV file and a Fixed length file, I want to read records from them and convert them in object of bean classes, currently I am using flatworm API to do the same, but I have to process nearly 40,000 records from files. What I want to do is that I want to convert the file into list of bean class objects at once which I am not able to achieve with flatworm. Flatworm is taking one record and then returning me one bean object w.r.t the record read from the flat file. Is there any other API with which I can convert the flat file's content to list of bean class objects , or this can be achieved in Flatworm API itself ? Following diagram shows what I want to achieve
