Get error while loading Muscle Applet on "SmartCafe Expert 3.2 72k" Smart Card?

Hi,

1) No. This is the "compile once load anywhere" part of javacard applets, modulo
availability of particular APIs.
Newer card shall accept old cap files, but not the reverse.

2) Not sure what "jtop" means, but i would say no. Only some very particular old
gemalto javacard required a specific off-card verification/transformation step
before the cap file is accepted. But Smartcafe, IIRC, is a G&D card, so no
specific tool should be required.

3) in your trace you're not INSTALLing anything yet, you're merely LOADing,
which is the first step, when the classes are copied inside the card. install is
the second step, in which the applet class is instanciated. The parameters
required for the applet may be in the spec, or can be understood by reading the
code. I don't know them, and that's not the problem yet.

4) 6A80 = bad command data. Your cap file is not accepted at the very first
"LOAD" APDU.
The problem is, this code is very generic and the reason is not easy to guess
- this may be because the card does not support javacard 2.2.2, only jc 2.2.1.
- this may be because the apdu is too long for this card. The buffer size in the
card (=max apdu size) is not always 5+255+1 data bytes.
I don't remember if the class version is still embedded in cap files, but you
could also try older jdk versions if nothing else works (jdk 5 or 6 instead of
jdk7, even if the effect of this is unsure)

Have a try with a precompiled applet, or by using shorter apdus, e.g. <128 bytes
(I don't know how to do that in gpshell).
That would be my own first steps.

Also, why not compare your generated cap file with a precompiled cardedge.cap
file? the cap file format is documented in the jcdk specs.

After that, I would be cautious with gpshell, install is a strangely named
command here. Have a look at the doc, it's better to avoid "combined" commands.
If you have a load command, go with that, and deal with the instanciation
(install) later.

Last but not least, do not use any -nvlimit et al. parameter, this is useless
for testing, this is only a way to limit the available card resources. Since you
don't know exactly what resources are required, it's better to avoid some
additional problems and not use these limiting options.

At least, the keys/auth part is OK :)

Sebastien

Response <-- 6A80
load() returns 0x80206A80 (6A80: Wrong data / Incorrect values in command data.)
I've compiled Muscle Applet source using Apache Ant by JavaCard 2.2.2 and JDK
7u2, so that the .cap file (CardEdge.cap) size is 16.2 KB.
1) Is the applet compilation method different for different smart cards?
(In the build.xml file, there is not any smart card specific information to modify!
I've downloaded Muscle source from
here: https://github.com/martinpaljak/MuscleApplet)
2) Does the applet compilation differ in JCOP and JTOP cards?
(Compilation process with JavaCard 2.2.2 works fine, but with JavaCard 2.2.1,
I get errors!)
3) Could you tell me the complete and correct parameters for "install" command
of GPShell for the specified card?
And...
Response <-- 6A80
load() returns 0x80206A80 (6A80: Wrong data / Incorrect values in command data.)
??
Thanks In Advance.
