This topic is a little off CXF Forum but I thought I would try anyways to see if someone has come across this.
I am working on a JAXRS method to upload a file with AngularJS client. I followed the sample found here for the AngularJS code https://uncorkedstudios.com/blog/multipartformdata-file-upload-with-angularjs. On the server side, the method is found but I run into NullPointerException for the header. I will post the stack trace at the end here. My CXF JAXRS interface : @Path("/images") public interface LinkableImages { @POST @Path("/upload") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.MULTIPART_FORM_DATA) public List<Link> uploadFile(@Multipart(value = "userId", type = "application/json")Long userId, @Multipart(value = "folder", type = "application/json") String foldername, @Multipart(value="file") Attachment attachment) throws Exception; } My html file upload controller with AngularJS: <div data-ng-controller = "uploadCtrl"> <input type="file" file-model="myFile"/> <button data-ng-click="uploadFile()">upload me</button> </div> The AngularJS code for the HTML file input: app.service('fileUpload', ['$http', function ($http) { this.uploadFileToUrl = function(file, uploadUrl){ console.log("file about to be uploaded is "+ file); var fd = new FormData(); fd.append('file', file); fd.append('userId', 3); fd.append('folder', '') $http.post(uploadUrl, fd, { transformRequest: angular.identity, headers: {'Content-Type': 'undefined'} }) .success(function(){ console.log("done post"); }) .error(function(data){ console.log("failed to post "+data); }); } } }]); app.controller('uploadCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){ $scope.uploadFile = function(){ var file = $scope.myFile; console.log('file is ' + JSON.stringify(file) + ' file is '+ file); var uploadUrl = "http://localhost:8080/note/soa/linkableImages/images/upload";; fileUpload.uploadFileToUrl(file, uploadUrl); }; }]); This is the stack trace in the server log: [2015-04-16 10:30:29,427] DEBUG MultipartFilter 114 doFilterInternal - Request [/note/soa/linkableImages/images/upload] is not a multipart request [2015-04-16 10:30:29,428] INFO CsrfHeaderFilter 31 doFilterInternal - setting csrf token in the cookie [2015-04-16 10:30:29,446] DEBUG ServletController 219 invokeDestination - Service http request on thread: Thread[http-nio-8080-exec-64,5,main] [2015-04-16 10:30:29,448] DEBUG AbstractHTTPDestination 224 invoke - Create a new message for processing [2015-04-16 10:30:29,487] DEBUG Headers 380 copyFromRequest - Request Headers: {Accept=[application/json, text/plain, */*], accept-encoding=[gzip, deflate], accept-language=[en-us], connection=[keep-alive], Content-Length=[1113], content-type=[undefined], cookie=[JSESSIONID=9D0598F4A5473149F59C385AC83AF11A; XSRF-TOKEN=d1b24eff-67e3-42f0-8707-7b4d1cbb9f24], dnt=[1], host=[localhost:8080], origin=[http://localhost:8080], referer=[http://localhost:8080/note/user/note], user-agent=[Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/600.2.5 (KHTML, like Gecko) Version/8.0.2 Safari/600.2.5], x-xsrf-token=[d1b24eff-67e3-42f0-8707-7b4d1cbb9f24]} [2015-04-16 10:30:29,512] DEBUG LogUtils 452 doLog - Could not determine bean name for instance of class org.apache.cxf.bus.managers.PhaseManagerImpl.
