Subject Re: [digester] Help needed
Date Mon, 29 Nov 2004 08:42:19 GMT
Hi Ray,
My advice is to create 2 utility classes one to manage the process of 
the ArrayList and the Map.

class MyArrayList extends ArrayList {
private String name;
public void setName(String name){;}
public String getName() {return name}

class MyHashMap extends HashMap {

public void putIt (MyArrayList obj) {
    super.put(obj.getName(), obj);
and .... (see below) ( the name and parameters of the rules could be 
innaccurate ;) )
