a little confused about "Default selected"

[trgorce]

Recently I am a little confused about "Default selected".
I installed my java card applet with the Default Selected application privilege. In my opinion, it means that I can send applet commands even if the applet is not selected. But the fact shows I am wrong.
I tried to send applet commands but I received the error that indicates that I should select the applet before doing it. What exactly does it mean?

I also think that after I installed the applet with the default selected application privilege, I can send command even if the applet is not selected.

But it seems that we are wrong.

Hey guy.
There are some mistake you may have.

In install applet period, you could install java card applet with the Default Selected application privilege. It means that when the card need to set one application to become Default Selected, this application could be chosen and other applications which don't have that privilege can't be chosen.

Hi my friend!

You are wrong.

Default Selected means that when the card is powered on, the applet with privilege can receive APDUs you send by default.
