java - CXF 3.1.6 file upload, attachment datahandler input stream is null -


i'm using cxf , working on file upload i'm receiving file content attachment. upon debug see file payload being present in datahandler object of attachment, when inputstream, content null.

code snippet:

@post @consumes({ mediatype.application_json, mediatype.application_xml,         mediatype.media_type_wildcard }) @produces({ mediatype.application_json, mediatype.application_xml }) @path("/{catalogid}/file") public catalogresponse addfile(@context httpheaders headers,         @pathparam("catalogid") string catalogid, @multipart(value = "requestfile")attachment file,         boolean autolaunch) {     catalogresponse res;     try {         inputstream = file.getdatahandler().getinputstream();         buffer = new bytearrayoutputstream();         int read = 0;         byte[] data = new byte[1024];          [enter image description here][1]while ((read = inputstream.read(data, 0, 1024)) != -1) {                   buffer.write(data, 0, read);                 }         buffer.flush();     }catch (exception ex) {      //handle exception     }

please find data below. see input stream marked 'closed' causing issue, guess.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
