struts2 token ajax,How to pass a struts2 token via ajax without a form?

I am trying to use the token interceptor that ships with Struts in order to implement a CSRF check. However instead of using a

I am making an AJAX call from within some JS:

foo.jsp:

var strutsToken = "";

bar.js:

$.ajax({

url: '/endpoint',

data: strutsToken,

dataType: 'jsonp',

cache: true,

success: function() { console.log('success'); },

error: function() { console.log('failure'); }

});

I've confirmed the token value is making it into the JS variable:

> strutsToken

"N3ZLLLR2Y3QGMZP0L3UCYWI5CO5NYZEY"

Unfortunately when that AJAX request is made an invalid-token error is thrown on the server.

Is what I am attempting to do possible and if so, how?
