Upload file using Ajax and Apache CXF

I'm not so familiar with Ajax and client side application (I'm mainly a server side developer). I need to add to a simple HTML page, a button that uploads a file and sens it to a Apache-CXF service.

I don't succeed to make this "hand shake" between client and server. I get:

java.lang.RuntimeException: org.apache.cxf.interceptor.Fault: Couldn't determine the boundary from the message!

This is the definition of the service in Java:

@CrossOriginResourceSharing(allowAllOrigins = true)
public class NLPRestService {

    public void uploadFile(@Multipart(value="file", type="text/plain" ) InputStream file) {
        //Here will be the code that handles the file content - I'll know what do with it once I'll succeed to get here

This is the HTML file:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
<html xmlns="http://www.w3.org/1999/xhtml">
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <script type="text/javascript" src="js/jquery/jquery-2.1.1.min.js"></script>
        <script type="text/javascript" src="js/jquery/jquery.ui.widget.js"></script>
        <script type="text/javascript" src="js/parseText.js"></script>
        <script type="text/javascript" src="js/uploadPosRules.js"></script>
        <script src="bootstrap/js/bootstrap.min.js"></script>
        <link href="bootstrap/css/bootstrap.css" type="text/css" rel="stylesheet" />
        <div style="padding: 20px;">
            <form id="uploadPosRulesform" >
                <div style="width: 700px;">
                    Upload new POS Rules File <input id="fileupload" type="file" name="file" /> 
                    <input  id="submit" value="upload POS RULE file" type="button"  onclick="uploadFiles()" />
            <!-- Here comes another form that do another thing - irrelevant  -->
            <form id="form">

And finally the JavaScript code that does the AJAX call:

function uploadFiles() {
    event.stopPropagation(); // Stop stuff happening
    event.preventDefault(); // Totally stop stuff happening


    // Create a formdata object and add the files
        url : '../services/nlpService/uploadPosRulesFile',
        type : 'POST',
        data: { file: $('#fileupload').val()},
        cache : false,

        dataType : 'text/plain',

        processData : false, // Don't process the files
        contentType: 'multipart/form-data',
        //contentType : false, // Set content type to false as jQuery will tell the server its a query string request
        success : function(data, textStatus, jqXHR) {
            if (typeof data.error === 'undefined') {

            } else {
                // Handle errors here
                console.log('ERRORS: ' + data.error);
        error : function(jqXHR, textStatus, errorThrown) {
            // Handle errors here
            console.log('ERRORS: ', jqXHR, textStatus, errorThrown);
            $('#alert').css('display', 'block');


It might be really basic issue (because I'm really not fully understand it...) - I'll appreciate your help!

Thanks a lot


contentType: false,

Try the above. This will force jQuery to generate the contentType headers and it will include the boundary information. If you sniff the http message that you are sending to the server you will see that now you are sending something like this

Content-Type: multipart/form-data; boundary=???
