Re: [digester] NullPointerException
Posted by Simone Tripodi <si...@apache.org>.
Patrick,
just replace
71 digester.addObjectCreate("collection", XMLReader.class);
with
digester.push(this);
Otherwise
30 ArrayList<ArrayList<String>> docs;
with
30 ArrayList<ArrayList<String>> docs = new ArrayList<ArrayList<String>>();
and remove line 64
I suggest you the first option
Simo
