Thank you for your reply.
I tried your test applet. Unfortunately, that also did not work for me.
You can see the pyAPDU tool error and the
JCIDE window of what i tried below:
What are the
specifications of Java Card that you are using to install this 'test applet'?
Thanks,
Priyanka

I am quite new to Java Applet development. JAVACOS
JCIDE and pyADU are the only tools I have used until now.
I don't have JCOP tool. Can I download it from somewhere or I should buy from NXP?

I tried to install the CAP file that you sent me using pyAPDU tool.
That is also not getting installed.
P.S. I am using the latest version of JAVACOS JCKit 5.x

Hello,
I could install the CAP file that you sent with snooper download tool.
But, how can I verify if it is successfully installed or not?
Because when I am trying to select applet in pyAPDU tool after installing the applet, it still gives below error
Code: Select all
Select Applet error: global name 'util' is not defined
Thanks

Thanks a lot for your tremendous help. I can install and select the applet on snooper(the tool that you suggested).
But I still don't know how to generate a CAP file for my
.java file without JCOP tool.
Because the CAP file generated by
JCIDE is not getting installed on my Java Card.

Thank you so much for your help. I can now
upload, install and select the CAP file you sent me.
I have one question. Is there any other free
CAP converter tool like snooper which can convert my java file into CAP file in the format of your
test.cap zip file that you sent me?
