javascript - Fine Uploader error with internet explorer 10 -

i using fine uploader 3.7.0 in project chrome , firefox , works fine, internet explorer 10 files uploaded correctly user "upload failed" error message, demo tests:

<script> $(document).ready(function() {      var errorhandler = function(event, id, filename, reason) {             qq.log("id: " + id + ", filename: " + filename + ", reason: " + reason);         };      var myuploader = new qq.fineuploader({         element: $('#basicuploadbutton')[0],         multiple: false,         callbacks: {             onerror: errorhandler         },         request: {             endpoint: '/fineupload/receiver'         }     }); }); </script> <div class="fineuploader">     <span>please upload files automated process.</span>     <div id="basicuploadbutton" class="upload-btn"></div> </div> <br /> <div><a href="#" onclick="window.close()">close window</a></div>  

i debugged servlet , see sending this:

writer.print("{\"success\": true, \"uuid\": \"" + requestparser.getuuid() + "\", \"originalfilename\": \"" + requestparser.getfilename() + "\"}"); 

so think json supposed correct.

any ideas why can failing ie10? tried compatibility modes , didn't work.

updated: console log:

[fineuploader 3.7.0] error when attempting parse xhr response text (syntaxerror: invalid character)   id: blog.jpg, filename: upload failure reason unknown, reason: [object xmlhttprequest] 

thanks!

the problem due json response creating in java.

looking @ network tab in ie10 developer tools (thanks ray advice) get:

{"error": "java.io.filenotfoundexception: c:\data\uploads\fd9b5240-5661-4f07-a216-7a76b2250b00_c:\folder\blog.jpg (the filename, directory name, or volume label syntax incorrect)"} 

i using

writer.print("{\"success\": true, \"uuid\": \"" + requestparser.getuuid() + "\", \"originalfilename\": \"" + requestparser.getfilename() + "\"}"); 

instead of

jsonobject json = new org.json.jsonobject(); json.put("success", true); json.put("uuid", requestparser.getuuid()); json.put("originalfilename", requestparser.getfilename()); writer.print(json.tostring()); 

works fine every browser.

anyway, needed avoid file name ie10 manages (c:\folder\blog.jpg) had use

json.put("originalfilename", getcorrectfilename(requestparser.getfilename())); 

with getcorrectfilename(string s) removing "c:\folder\" part.
