Hello Folks.
I am trying to get my head around on how java applet loading works for
sysmo-isim-sja2.
At first I used the following, updated example to compile a
HelloSTK2.cap: https://github.com/mrlnc/HelloSTK2.git
This works fine and it also loads fine on sysmo-usim-sjs2 using shadysim.py
Now I want to load the exact same file to a sysmo-isim-sja2.
I tried with shadysim_isim.py from
https://github.com/herlesupreeth/sim-tools:
---------------8<---------------
$ python shadysim_isim.py --pcsc 2 -l
/home/owner/work/simcard_applet_loading/HelloSTK2.cap -i
/home/owner/work/simcard_applet_loading/HelloSTK2.cap
--enable-sim-toolkit --module-aid d07002ca44900101 --instance-aid
d07002CA44900101 --nonvolatile-memory-required 0100

--max-menu-entries 05 --kic 56B6B26346DEF2A74BC8DFAF3BEA71D6 --kid

And I also tried with gp.jar from https://github.com/mrlnc/HelloSTK2.git
---------------8<---------------
$ java -jar ./gp.jar --key-enc 56B6B26346DEF2A74BC8DFAF3BEA71D6

CAP loaded
Error: INSTALL [for install and make selectable] failed: 0x6A80 (Wrong
data/incorrect values in data)
---------------8<---------------
As it seems gp.jar seems to work better than shadysim_isim.py.
Unfortunately I have no experience in java card programming yet, so its
difficult for me to tell where the error could be.
(When I run gp.jar once more it tells me "Error: STRICT WARNING: Package
with AID D07002CA44 is already present on card", I can also delete the
applet again, so apparently its kind of loaded...)
Is there anyone here who managed to load an applet to a sysmo-isim-sja2
and how?
best regards.
Philipp
