$.ajax unexpected token error on tomcat server (GWT)

we are currently working on a GWT Project and ran into an unexpected token error called by .parseJSON in this function after compiling and running the project on a tomcat server. In dev mode on eclipse this worked fine:

$.ajax({
  url: "index/sequences/seq.json",
  datatype: "json",
  }).success(function(data) {
var data = jQuery.parseJSON(data);
  });

This is the json; validated by jsonlint

{"cont":[{"values":"left arm up,turn left,sit","name":"greet&go"},{"values":"turn left,turn right,walk back","name":"strange moves"},{"values":"kick right,turn right, right arm up","name":"right moves"},{"values":"kick right,walk,sit","name":"sequnece 4"},{"values":"sit,stand,kick left","name":"up&down"},{"values":"stand,turn right,sit","name":"testin"},{"values":"turn left,kick right","name":"kickit!"},{"values":"turn right,look up,left arm out,walk","name":"greet the audience"}]}

After some debugging i realized, that the parseJSON is called two times; first time with no errors, right data and all, second time with empty data, what calls the error.

Any help welcome! THX!

datatype should be dataType, and if you are supplying the dataType parameter (or passing the appropriate Content-Type: application/json header), you don't need to parse the json.

$.ajax({
  url: "index/sequences/seq.json",
  dataType: "json"
}).success(function(data) {
  console.log(data);
});
