try number two:

i have ajax request looks this:

$.ajax({     url: "/someplace",     datatype: "json",     async: true,     cache: false,     data: {         number0: 0,         key: littlekey     },     success: function(data, status)     {         alert(data);     } }); 

and works expected.

and can specify type : "get" in other options.

maybe try having .jsp print data no matter what, , print data receiving.
