Java Card

Hello everybody.I have just tested some existing applets from the Java Card Toolkit 2.1.1 and I have also created and tested successfully my own applet.

I am thinking to develop a friendly G.U.I in general Java(probably can be an applet or an application) using the Visual Cafe for Java from the Symantec in order to integrate the command Dos line for taking control of the Java Card Toolkit commands into the GUI Java applet.
(e.g.//READ the record
0x00 0xB2 .........//It is assumed that this is contained in the file read_record.scr file
//and from the dos command line you can just write:
//c:\>apdutool read_record.scr )

For example, I will just create a button to send the above APDU to the jcwde.(e.g READ a specific record or add A NEW RECORD,Delete this Record,Store this RECORD)

I was wondering if it is possible to integrate the DOS command line with a Java applet(not a Java Card applet but GUI applet in general Java) and everything can be hidden from the user.

Or can I integrate the DOs line only with a Java application, and how?(probably with the System library...?)

I will appreciate any thoughts and assisstance for this idea.

Thank you.
