Whats wrong with this code

Hi All,

Below is the code for a Model class that gets called from my controller servlet. The problem is that the List<List<String>> object does not get populated with the column details. I just get a List of lists where each list is not containing the row data and is just blank. The for loop at the end just prints the blank data. Please help:

Using tomcat 5.5 and JDK 5.

You're reusing the same List instance each time and wiping it clean.
You need to create a new instance each time otherwise everyone will end up with a reference to the same List<String>, which will be empty.
