Jetz API on nokia 6131 secure element

Question

Hi,
i've developed an applet that uses the Jetz Api in order to write on nokia 6131 mifare.
When i try to upload the applet i receive this error:
"Reference data not found".
I succeed in uploading another applet that doesn't use JetZ Api.
Can you help me?

Answer 1

Thank you for your quick reply.
*/identify*
What do you mean with /identify? Sorry for the question, but I am new to Java Card.
The command itself results in an error
