[flexcoders] building a dataprovider in Java

[netdeep]

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}
     ]);
