I want to create EFs with some data which is defined by myself and store them in the java card. Then I would like to use an applet to select and read these data. Is there any way to do this? How can I implement? Thanks a lot

You have to implement a proprietary version of CREATE FILE and the ISO versions of READ BINARY and UPDATE BINARY by yourself according to your needs.
FYI: ISO applet
viewtopic.php?f=17&t=31 is really a good example for you to learn more on this part.

Many thanks for your help. I will try to study ISO applet first.
