nested logic tag

[Kathy Zhou]

I need your help on how to use nested logic tag:

I have a ArrayList list1. each element of the list1 is a ArrayList too. In
Java code, it will be like:

for(int i=0; i<list1.size();i++){
        ArrayList sublist=(ArrayList)list1.get(i);
   for(int k=0; i<sublist.size();k++){
        System.out.println(sublist.get(k));
   }
}

Now if I set list1as an attribute of a bean, how could I use logic tag to
show the data in the sublist? Can I use nested logic tag? It seems not
working.

Thanks for your help,

Kathy
