javascript - Why won't my images load up from my java servlet? -

i'm connecting ip cam via python , running script in java servlet. loading each image in java , converting byte array base64 encoding. lastly ask data via ajax through json object. don't receive errors images don't appear either.

javascript:

$().ready(calltoserver);         function calltoserver(){             $.ajax({                 type:"get",                 url:"droneservlet.do",                 async:true,                 data: null,                 datatype:"json",                 success: drawimage,//function success                 error: badrequest//function error             });             settimeout(calltoserver,5000);         }         function toarray(str){             var i;             var bytes=[];             for(i=0;i<str.length;i++)             {                 bytes.push(str.charat(i));             }             return bytes;         }         function badrequest(){             console.log("failed");         }         function drawimage(json)         {             var img = json.imgdata[0].imagetodisplay;             var bistr=toarray(img);             var data = bistr.join('');             //var base64 = window.btoa(data);             document.getelementbyid("dynamic").src = "data:image/jpeg;base64," + data;         } 

java snippet:

    byte[] imgdata = pythonrunner.grabphotobytes();//loads single image , convert byte[]     jsonobject jsonresponse = new jsonobject();     jsonarray jsonarray = new jsonarray();     jsonobject img = new jsonobject();     string encodedimg = base64.encodebase64string(imgdata);     img.put("imagetodisplay", encodedimg);     jsonarray.add(img);     jsonresponse.put("imgdata", jsonarray);     out.println( jsonresponse.tojsonstring()  ); // send weatherdata collection in json format 

sending image base64 worst thing here, image , save on server local system using imageio class, , of course name(maybe random).

first have saved data following, on server system
/root/image_folks/trejon_house7222015-0342.jpeg name random or anything.

response image name json response client simple string, , client ask /get-image cgi/servlet image(like /get-image?id=trejon_house7222015-0342).

now have simple servlet loads server local file , response client, don't forget specify mime type
