Where can I find the JCOP tutorial?
The " Load" APDU command of my card is a little different from that of the JCOP.
So if I use JCOP to load applets to my card, there will be error.
So I wonder if I can modify the default parameters of APDU command in JCOP.
Or is there a JCOP tutorial ?
I can't find help in Eclipse help content. It always tells me :

What do you mean by
The " Load" APDU command of my card is a little different from that of the JCOP. ? Is your card GP compliant?

Thanks for your reply!Let me explain the difference.
The default Load command in JCOP shell is : 80 E0 P1 P2 Lc Data 00,
Here Lc is set to FF by default,so the length of whole Load command must exceeds FF.
While in my card reference , Load command is : 80 E1 P1 P2 Lc Data 01. And it is said that the length of APDU command should not exceed FF.
So if I load applets onto my card by JCOP, there will be 2 errors:
1.invalid length ;
2.last byte of the command should be 01 but not 00.

The LOAD command instruction is 0xE8 and not 0xE0/0xE1.
Lc is one byte, so how can you exceed FF?
Optionally the LOAD response can include a receipt (delegated management). If your card mandates a response length of 1 byte (Le=01) it means that no receipt is expected --> receipt length 00. JCOPs LOAD command has Le=0x00 set by default --> response length undefined. This is in accordance with Java Card API, which follows the ISO 7816-4 APDU structure.
Let's look at the help of the JCOP tools upload command:usage: upload [-p|--progress][-c|--components][-r|--random][-l|--package package-name][-s|--sd SD-AID][-m|--params parameters][-b|--block_length length][-a|--auto][-d|--load-debug] CAP-file
...
-c|--components
Load CAP-file component wise.
-r|--random
Load with random APDU length.
...
-b|--block_length length
Max. block (APDU) length sent to the card during package upload.
length Max. block (APDU) length.
So you can set the block length --> Lc as you wish.
