=== 8.1.1.3 Functional Limitations ===

The definition of the supported subset of Java Card RMI for the Java Card Platform, Version 2.2.2, implies functional limitations during the execution of Java Card API remote methods: 

 

  *CAD client application remote objects cannot be passed as arguments to remote methods.    

  *Card remote objects cannot be passed as arguments to remote methods.    

  *Applets on the card cannot invoke remote methods on the CAD client.    

  *Method argument data and return values, along with the Java Card RMI protocol overhead, must fit within the size constraints of an APDU command and APDU response, respectively.
