Serialize your map into JSON and then put it as string in your configuration. There is no way to put a whole object into it, because the whole configuration will be written as a XML file.

GSON is quite good at it: http://code.google.com/p/google-gson/ Here is the tutorial about how to serialize collections: http://sites.google.com/site/gson/gson-user-guide#TOC-Collections-Examples
