Fail with java sample codes on PostNewTarget

Vuforia veritabanımıza resim upload etmek için hazır java sınıflarınızı kullanmak istedik fakat çözemediğimiz bir sorun var.

DeleteTarget, GetAllTargets, GetTarget fonksiyonlarını çalıştırıyoruz ama  PostNewTarget ve UpdateTarget fonksiyonlarını çalıştırdığımızda aşağıdaki gibi bir hata alıyoruz.

We try to upload images to cloud database with java samples from vuforia developer web site. 

With same samples we can run DeleteTarget, GetAllTargets, GetTarget  functions but can not run PostNewTarget and UpdateTarget functions.

We get following error:
