If you wanna pass an actual array (ie. an indexed array) then you can do:

 $.post('/url', {'someKeyName': ['value','value']});

You can also build a param string by looping other the data (in my case a multi-select)

$(".choosenItems option").each(function() {
        chosenStr = chosenStr + "&chItems=" + $(this).val();
});

so if you create a queryString of

   ...?name=Fred&name=Joe&name=Sally

then in your servlet you can do

String names[] = request.getParameterValues ("name");
