On how to define the layout you can use:

- XML, you can rely on Commons Configuration
- ~ delimeted, rely on standard Java class FileInputReader
  and StringTokenizer

take a look at Apache Commons BeanUtils

http://commons.apache.org/proper/commons-beanutils/

as stated in the user guide

http://commons.apache.org/proper/commons-beanutils/javadocs/v1.9.3/apidocs/org/apache/commons/beanutils/package-summary.html#standard

you can access your accessor method via

PropertyUtils.getSimpleProperty(anIstanceOfPerson,"firstName")
