Problem loading Java Applet to smartcard
Hi!
The load command response is a 0x6A88.
Does the smartcard verifiy the contents of the cap file before the last block is loaded?
Here is the dump:

INS=0xE4 is DELETE and not LOAD.
# 3
SW1-SW2 = 0x6A80 is 'Incorrect values in data field'.
# 4
Okay I assume you've read the first (wrong) dump with E4?The text message is wrong you're right.But what about the load command?Is the cap file wrong?Thanks.
# 5
Some reasons I can think of:
- DAP mandatory
- package AID is already present on-card
- card does not accept CAP file version (e.g. Card is compliant to JC 2.1.1 but CAP file indicates JC 2.2.1 package version)
- the structure of the CAP file component is not JC compliant
- card does not accept debug and/or custom components
- the size is too big
The INSTALL[for load] command is accepted, so we can rule out DAP and AID issues.
Your LOAD command indicates JC 2.1.1 . If you don't have a ancient JC version this should not be a problem neither.
JC compliancy:
It seems that the packa_name_info is missing in the Header component. Furthermore the order for Import and Applet component is not ?correct?.
Size:
Check if your card has sufficient free EEPROM available (Method component is already ~8.6kB).

Hi lexdabear!
Is a little bit strange!
I thougth the smartcard checks the first TLV value (COMPONENT_Header tag 01) and complains about a wrong version or something. But then I used very short LOAD APDUs and I always get an error after the second load command.
Here is the trace:

Looking back at your previous post the package AID in the INSTALL[for load] command does not match the package AID in the header component.
Debugging the LOAD process can become quite cumbersome. Try to load this cap file with JCOP tools on the simulator and compare the APDUs. If you don't have the tools available you can send me the cap file and I will post the trace.

HI!Okay I've send you an email.Thanks in advance.

I took the raw CardEdge.cap file apart into the components defined in JC VM. Then I zipped it back to CardEdge.cap, containing each component:StaticField.cap
RefLocation.cap
Method.cap
Import.cap
Header.cap
Directory.cap
ConstantPool.cap
Class.cap
Applet.cap
Problems I found:
- According to JC VM spec. all components but Applet, Export and Debug are mandatory. In our case not only the optional Debug and Export components are missing, but also the mandatory Descriptor component. JCOP Tools shows me thisjcshell: Cannot read <C:/javacard/CardEdge.cap>: Incomplete CAP file, missing mandatory component: Descriptor.cap
- The package AID in the INSTALL[for load] command does not match the package AID in the header component --> 0x6A80 after the first LOAD command
