Fail with java sample codes on PostNewTarget

November 20, 2015 - 4:30am #1

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: 

run:

Hello,

We believe this is related to the JSON schema being incorrect.

For this case, the `image` and `application_metadata` are not sent as String JSON objects? Can you send the body of the request in raw form as you are sending for further evaluation?

If you prefer to keep that private, please upload to a file share service and PM me the link.

Thanks

Hello,

This is puzzling. We tried running this in our environment and it works fine.

The result code is basically a catch-all and really doesn't provide any feedback as to the actual issue.

https://library.vuforia.com/articles/Solution/How-To-Interperete-VWS-API-Result-Codes

I will continue to investigate.

Thanks.

Yes, I get the same failure. I have to modify the source code with image path and server access keys. Also, I tried with the test metadata given in the samples too, it throws same error

@brainbreaker - What happens if you use our unmodified sample code? Do you get the same failure?

I'm trying to isolate if this is an issue with your code, your network connection, or our service. At this time I have no evidence that it is the latter.

Thanks

@medabit Sorry, Here's the new link to the code: http://pastebin.com/wDSgrYbq

And yes, I am using the PostNewTarget.java from official samples only.

 

Thanks!

Hello,

Your link does not work - the post was removed.

That's OK because we have sample Java code available for download for the VWS APIs:

https://developer.vuforia.com/downloads/samples

Thanks

Are you able to upload the same image successfully using the Target Manager?
