It looks like that you're passing List<String> to the datatable instead of List<DTO>. Or, at least, trying to invoke getCell() on a String object while it isn't available.Check http://balusc.xs4all.nl/srv/dev-jep-dat.html how to use datatables.

I'm not going to debug it for you, but the 1st thing I see is that you're not respecting the naming conventions of Java. First fix it and then we'll see further.Useful reference: http://java.sun.com/docs/codeconv/html/CodeConventions.doc8.html
