I need to send APDU like /send b07000000411222233 to my JCOP31 V2.2 card. In above APDU, I am not giving any value of P1 P2 as this indicates some extra parameters. but if I want to use these P1P2, what should I do?

I am experiencing a strange issue. For the same APDU command, when I run my applet on Java Card 2.1.1, it returns 0x9000, but returns 0x6D00 on Java Card 2.2.2. As we all know, JavaCard 2.2.2 is compatible with JavaCard2.1.1, so why does this happen?
Hope experts here figure me out.
