You probably want a List of Maps. Is this coming from a ResultSet from jdbc? In Java-ish pseudo-code, you'd do something like this:
- List<Map<String,Object>> list = new ArrayList<Map<String,Object>>(); - For each row in the result set -- Map<String,Object> row = new HashMap(); -- For each column in the result set metadata --- row.put(column name, row value) -- list.add(row) and then return the list to Flex. -- Maciek Sakrejda Truviso, Inc. http://www.truviso.com -----Original Message----- From: netdeep <deep...@chartertn.net> Reply-to: flexcoders@yahoogroups.com To: flexcoders@yahoogroups.com Subject: [flexcoders] building a dataprovider in Java Date: Wed, 15 Apr 2009 13:03:03 -0000 I posted a few weeks back about how to create a chart dataprovider in Java to pass to Flex and the response I got back was to use Maps. I got sidetracked with other aspects of the code and now that I'm trying to code it, I am really drawing a blank. How would you create the following dataprovider in Java without using a custom object (i.e., the next data structure may have more or less elements than this one and I would need to use generic names for each data pair)? public var expenses:ArrayCollection = new ArrayCollection([ {Month:"Jan", Profit:2000, Expenses:1500}, {Month:"Feb", Profit:1000, Expenses:200}, {Month:"Mar", Profit:1500, Expenses:500} ]);
