There does not appear to be a findAll method. How to find all the documents in the collection testCollection ?

How-To
You have to use the DBCollection.find() method, which:

Select all documents in collection and get a cursor to the selected documents.

So, what you have to do, is:

view plaincopy to clipboardprint?

1. DBCursor cursor = coll.find();  
2. while (cursor.hasNext()) {  
3.    DBObject obj = cursor.next();  
4.    //do your thing  
5. }
