It looks like you want to convert it to Json, using google gson http://code.google.com/p/google-gson/ its very easy

"Provide simple toJson() and fromJson() methods to convert Java objects to JSON and vice-versa"

Here is what I mean :

Gson gson = new Gson();
gson.toJson(map); //where map is your map object
